Discuss about the chemical composition of various types of lava rocks and magma. How is their chemical make-up related to their era and geographic origin?

Answer:

1.546 L.

Explanation:

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

(P₁V₁T₂) = (P₂V₂T₁)

P₁ = 600.0 mmHg/760 = 0.789 atm, V₁ = 4.31 L, T₁ = 400 K.

P₂= 1.1 atm, V₂ = ??? L, T₂ = 200 K.

∴ V₂ =  (P₁V₁T₂)/(P₂T₁) = (0.789 atm)(4.31 L)(200 K)/(1.1 atm)(400 K) = 1.546 L.

1. Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.

2.There are two basic types.

Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form.

Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass.

3. Erosion is the wearing away of the land by forces such as water, wind, and ice. Erosion has helped to form many interesting features of the Earth's surface including mountain peaks, valleys, and coastlines. There are many different forces in nature that cause erosion.

4. • Frost and Salt Wedging. One of the more common forms of mechanical weathering is frost wedging. ...

• Unloading and Exfoliation. ...

• Water and Wind Abrasion. ...

5. Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". This occurs in a type of glacier called a "valley glacier".

6. Rusting, a well known example of corrosion, is the breakdown of the metal iron. The reactants of this chemical reaction are iron, water, and oxygen, and the product is hydrated iron oxide, better known as rust. Rust, unlike iron, is crumbly, orange, and pretty much useless for building things.

7. rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.

8. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly ...

9. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface. Rock formed in this way is called extrusive igneous rock.

10. When water becomes saturated with dissolved minerals, particles can crystallize out of the water and form minerals. Chemical rocks form when minerals crystallize directly from water.

11. Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster.

12. Gypsum and halite

13. the repeating pattern of a mineral's particles forms a solid called a crystal. A crystal has flat sides, called faces, that meet at sharp edges and corners. a mineral has a definite chemical composition or range of compositions.

I hope this is what you’re looking for if not I’m very sorry :/

The formation of rocks, types of weathering, and characteristics of minerals are explained in detail. For instance, metamorphic rocks are formed by heat and pressure, igneous rocks are divided into intrusive and extrusive, and mechanical weathering includes processes such as frost wedging and thermal expansion.

1. Metamorphic rock needs heat and pressure to form.

2. The two types of igneous rock are intrusive (plutonic) and extrusive (volcanic).

3. Water, wind, and ice are three things that erode rocks.

4. Three examples of mechanical weathering include frost wedging, thermal expansion, and abrasion.

5. Plucking is when a glacier picks up rocks in the lower side.

6. Rust is an iron oxide (a type of corrosion) that forms in the presence of oxygen and moisture.

7. Acid rain is precipitation that contains higher than normal amounts of sulfuric or nitric acids. It's typically from pollutant gases in the atmosphere.

8. Magma cools slowly below the Earth’s surface.

9. Lava cools quickly on the Earth’s surface.

10. When minerals crystallize from water solutions, the narrow channels form veins.

11. When the hot water cools crystals form.

12. Halite, a mineral form of salt, is often left behind by evaporation.

13. The repeating pattern in a mineral is called its crystal lattice.

Answer:

Explanation:

Parameter given:

Volume of gas in the container = 22.4L

Pressure on the gas = 1.0atm

Temperature of the gas = 0.0°C

Problem 1

Coverting 0.0°C to Kelvin:

In order to convert 0.0°C to Kelvin, we apply the formula:

              K = T(°C) + 273

Where T is the temperature in °C and K is the unknown temperature in Kelvin:

               K = 0.0 + 273 = 273K

Problem 2

The combined gas law is also known as the general gas law. It is expressed as:

                   [tex]\frac{P_{1}V_{1}  }{T_{1} }  = \frac{P_{2}V_{2}  }{T_{2} }[/tex]

The expression combines both Boyle's law and Charle's Law.

Problem 3

Parameters given:

Volume of gas in the container V₁ = 22.4L

Pressure on the gas P₁ = 1.0atm

Temperature = 273K

P₂ = 1.50atm

Unknown: The final volume, V₂ = ?

Solution

From the given problem, we know that the temperature is constant. We apply Boyle's law. Boyle's law states that "The volume of a fixed mass of gas varies inversely a the pressure changes if the temperature is constant".

It is expressed as P₁V₁ = P₂V₂

The unknown parameter is V₂, we make it the subject of the expression:

                    V₂ =[tex]\frac{P_{1}V_{1}  }{P_{2} }[/tex]

                     V₂ = [tex]\frac{1  x 22.4}{1.5}[/tex]

                     V₂ = 15L

Problem 4

The unknown here is the new volume V₂ at constant pressure.

Given parameters:

Volume of gas in the container V₁ = 22.4L

Pressure on the gas P is constant

Intial Temperature T₁ = 273K

Final Temperature T₂ = 100°C , converting to K gives, K = 100 + 273 = 373K

From the given parameters, the unknown and the conditions guiding the equation, we apply Charle's law. Charle's law states that "The volume of a fixed mass of gas is directly proportional to its absolute temperature provided pressure is constant".

                 it is expressed as: [tex]\frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }[/tex]

We then express the unknown V₂ as the subject of the formula:

                       V₂ = [tex]\frac{V_{1} T_{2} }{T_{1} }[/tex]

                       V₂ = [tex]\frac{22.4 x 373}{273}[/tex]

                        V₂ = 30.6L

Answer:

2400 mL

Explanation:

[tex]Ca + 2HCl \implies CaCl_2 + H_2[/tex]

According to this equation, the stoichiometric ratio between [tex]Ca[/tex] and [tex]HCl[/tex] for the complete reaction is 1:2.

We know that the number of moles of [tex]Ca[/tex] can be calculated using the mole formula. (number of moles = mass / molar mass)

Moles of Calcium = [tex]\frac{60}{40}[/tex] = 1.5 mol

So the moles of [tex]HCl[/tex] = [tex]1.5 \times 2[/tex] = 3.0 mol

Volume of HCl solution = Moles of HCl/ concentration of HCl

Volume of HCl solution = [tex]\frac{3}{1.25}[/tex] = 2400 mL

Explanation:

Answer:

Light is used by plants in a complex system that uses the light and several other resources to produce food. The more food= the more the plant grows, but too much food can be unhealthy for the plant. Some plants require more energy and others require less, this is because of the environment that they are in.

Explanation:

Plants' growth is significantly impacted by the quantity and quality of light they receive, a process called photomorphogenesis. Not all plants require identical light conditions, which is referred to as photoperiodism. Moreover, the ability of plants to use a variety of light wavelengths for photosynthesis allows them to adapt to different light conditions.

The amount of light can significantly impact the growth of plants. Different kinds of lights can foster varying developmental responses in the plants. This is known as Photomorphogenesis, growth and development of plants in response to light. Light influences many functions in a plant beyond photosynthesis, like the timing of flowering, the determination of whether the plant will produce fruit or seeds, and the plant's size.

Also, not all plants require the same amount of light for growth, nodding towards the concept of Photoperiodism. Some plants may flourish best under less-intensive light or might need different types of light to germinate or flower. For instance, fluorescent (cool white) light, high in blue wavelengths, encourages leafy growth. On the other hand, Incandescent lamps promote flowering in some plants due to high richness in red light.

Photosynthetic organisms, like plants, have a mixture of pigments that absorb energy from a wide range of wavelengths. This ability is especially useful for plants growing in competition for light, underwater, or on the rainforest floor because they have limited access to sunlight.

Answer:

Hello! Your answer is Plants.

Answer:

504 J.

Explanation:

Q = m.c.ΔT,

where, Q is the amount of heat absorbed by ice (Q = ??? J).

m is the mass of the ice (m = 12.0 g).

c is the specific heat of the ice (c of steam = 2.1 J/g.°C).

ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = 0.0°C - (-20.0°C) = 20.0°C).

∴ Q = m.c.ΔT = (12.0 g)(2.1 J/g.°C)(20.0°C) = 504 J.

Ionic bonds are made by a transfer of electrons. Covalent bonds are made by sharing electrons.

Explanation:

For ionic bonds, use the group number to help you determine how many electrons an element can give or receive (Group 1 gives 1 electrons, group 2 gives 2 electrons, group 3A gives 3, group 5A receives 3, group 6A receives 2, and group 7A receives 1).

Covalent bonds have to be worked out using the total number of valence electrons and the octet rule.

Answer: If the indicator was a universal indicator, when it hits an acid, it'll turn red, when it hits a base, it'll turn blue.

Explanation:

If you are trying to observe a cell wall, you should look at a plant cell. There are only two different types of cells, which are plant and animal cells. The plant cell is the only one which contains a cell wall. Animal cells actually only have a cell membrane.

Cell walls, commonly found in plant or bacterial cells, have distinct structures based on the type of organism. Plant cell walls consist of cellulose, providing rigidity and structure, while bacterial cell walls contain peptidoglycan for protection and shape. Unlike these, animal cells do not have a cell wall.

If you wanted to look at a cell wall, the most common types you would observe would be those of plants or bacteria, as they are widely studied in biology. Plant cell walls are primarily made up of cellulose, giving them rigid structure for support, whereas bacterial cell walls are mainly composed of peptidoglycan, which provides protection against environmental stressors.

When observing a plant cell wall under a microscope, what you are seeing is a rigid layer outside the cell membrane that provides structure and support. For bacteria, the cell wall is a protective layer outside the cell membrane, which protects the bacterium and gives it shape.

In contrast, animal cells do not have a cell wall, but a cell membrane instead, which provides a flexible structure. It's essential to remember that cell walls vary significantly in composition and structure among different groups of organisms.

Answer:

Two half lives.

Explanation:

It is known that the decay of isotopes and radioactive material obeys first order kinetics.

Also, it is clear that in first order decay the half-life time is independent of the initial concentration.

That means for a sample 100% to decay to 50 % it will take one half-life, and to decay the remaining 50% to 25% it will take another half-life.

So, for a sample has 25% parent and 75% daughter it will have two half-lives.

The statement is true. The study of the quantitative relationship between the amount of reactants used and the amounts of products formed by a chemical reaction is indeed called stoichiometry. This concept underlies the understanding of the classification of the reaction.

Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions. Coefficients from the balanced chemical equation provide the relative numbers of these chemical species, thus allowing a quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction.

For example, when calculating the amount of product generated from a given amount of reactant, any other reactants required are assumed to be available in stoichiometric amounts (or greater). These coefficients are used to derive stoichiometric factors that subsequently may be used for computations relating reactant and product masses, molar amounts, and other quantitative properties.

Explanation:

Answer:

NaNO₃.

Explanation:

It is 90 g per 100 g water.

It is 110 g per 100 g water.

It is about 20 g per 100 g water.

It is about 40 g per 100 g water.

So, the most soluble salt at 50°C is NaNO₃.

The salt most soluble at 50°C is NaNO3 (sodium nitrate).

To determine the most soluble salt at 50°C, we need to consider the solubility data for each salt at this temperature. Generally, the solubility of salts increases with temperature, but the extent of this increase varies depending on the specific salt.

 The solubility of these salts at 50°C, in grams per 100 grams of water, is approximately as follows:

 - KNO3 (potassium nitrate): about 170 g/100 g H2O

- NaNO3 (sodium nitrate): about 220 g/100 g H2O

- KClO3 (potassium chlorate): about 24 g/100 g H2O

- NaCl (sodium chloride): about 360 g/100 g H2O

From these values, it is clear that NaNO3 has the highest solubility at 50°C, with a solubility of about 220 g/100 g H2O. This is higher than KNO3, KClO3, and even NaCl, which is known for its high solubility in water. Therefore, NaNO3 is the most soluble salt at 50°C among the options provided.

n is the no. of moles of the gas in mol.

R  is the general gas constant,

T is the temperature of the gas in K.

(V₁T₂) = (V₂T₁)

V₁ = 3.5 L, T₁ = 25°C + 273 = 298 K,

V₂ = ??? L, T₂ = 40°C + 273 = 313 K,

(V₁T₂) = (V₂T₁)

∴ V₂ = (V₁T₂)/(T₁) = (3.5 L)(313 K)/(298 K) = 3.676 L.

Concentration of the acid = 1.05M

Explanation:

Given parameters:

Volume of acid = 14.0mL = 0.014L

Volume of base = 28.23mL = 0.02823L

Concentration of the base = 0.521M

Unkown:

Concentration of acid = ?

The reaction equation is given below:

          CH₃COOH + NaOH → CH₃COONa + H₂O

To obtain the unknown concentration of the acid used in the reaction, we simply work from the known parameters of the given base.

Procedure:

       Number of moles of base = concentration of base x volume

      Number of moles of base = 0.521 x 0.02823 = 0.0147mol

      1mole of the base neutralize on mole of acid,

    Therefore, 0.0147mol of the acid would be neutralized by the base.

To find the concentration of the acetic acid,

Concentration of acid = [tex]\frac{Number of moles of acid}{Volume of acid}[/tex]

Concentration of acid = [tex]\frac{0.0147}{0.014}[/tex]

Concentration of the acid = 1.05M
