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.

An aerosol is a colloidal suspended in a .
An aerosol is a colloidal suspension in a gas, consisting of small particles or droplets that do not settle due to their small size. Examples include fog and smoke, where the dispersing medium is air. Understanding aerosols is important for their role in atmospheric processes and distinguishing them from other mixtures like solutions and suspensions.
Explanation:
An aerosol is a colloidal suspension in a gas. This means that an aerosol comprises tiny particles or droplets that are suspended within a gas. Unlike a suspension, where the particles can separate out over time due to their size (generally larger than 1 µm), the particles in a colloidal system, like an aerosol, do not settle because they are much smaller and range in size from about 2 to 500 nm. Aerosols can be composed of both solid and liquid particles dispersed in a gas, and these particles are stable enough not to settle quickly under the influence of gravity.
Examples of aerosols include fog, which consists of liquid water droplets dispersed in air, and smoke, which contains solid carbon particles also suspended in air. In both cases, the medium dispersing these particles is a gas (air), highlighting the defining characteristic of aerosols as a type of colloid. The significance of aerosols extends beyond simple examples, as they play integral roles in atmospheric processes, affecting weather, climate, and air quality, by influencing the scattering and absorption of radiation and serving as nuclei for cloud formation.
The ability of colloids, including aerosols, to scatter light, known as the Tyndall effect, further distinguishes them from solutions which are homogeneous mixtures and therefore do not exhibit this phenomenon. It's important to understand the distinction between aerosols and other types of mixtures, such as solutions and suspensions, to appreciate the unique physical and chemical behaviors of colloidal systems.

___solutions are good conductors of electricity.
lonic
Covalent
Heterogeneous
Gaseous
The answer is ionic
Answer: Option (a) is the correct answer.
Explanation:
A bond where transfer of electrons take place from one atom to another is known as an ionic bond.
An ionic solution is defined as a solution in which an ionic compound is dissociated into ions.
For example, NaCl is an ionic compound and when it is dissolved in water it dissociates as [tex]Na^{+}[/tex] and [tex]Cl^{-}[/tex] ions.
As it is known that electric current is the flow of charges. Hence, a solution that contains ions will be a good conductor of electricity.
Whereas in general, a covalent solution does not contain any ions.
Thus, we can conclude that ionic solutions are good conductors of electricity.
a shampoo bottle contains 553mL of air at 65C what is its volume when it cools to 22C
Answer:
V₂ = 0.483L = 483mL
Explanation:
Given parameters:
Inital volume of air in shampoo bottle V₁ = 553mL
Original temperature of the bottle T₁ = 65°C
Final temperature T₂= 22°C
Final volume of the gas in the bottle V₂=?
We first take the given units into standard units:
K = T°C + 273
For T₁ we have the temperature to be = 65 + 273 = 338K
T₂ = 22 + 273 = 295K
For the volume we convert to Litres or dm³
1000mL = 1L
V₁ = 553 x 10⁻³L = 0.553L
Now apply one of the gas laws to solve this problem.
From Charles law, we know that the volume of fixed mass of gas is directly proportional to its absolute temperature if the pressure is constant.
Charles's law is expressed as:
[tex]\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }[/tex]
The unkown in the equation is V₂ we the express it as the subject of the formula :
V₂ = [tex]\frac{V_{1} T_{2} }{T_{1} }[/tex]
Putting the parameters in the equation gives:
V₂ = [tex]\frac{0.553 x 295}{338}[/tex]
V₂ = 0.483L = 483mL

ml of oxygen for the complete combustion.
The hydrocarbon is
[MOE 2060]
a. C2H4
b. C2H2
с. С3Н8
d. C2H6
Answer:
a. C₂H₄Explanation:
At constant pressure and temperature, the mole ratio of the gases is equal to their volume ratio (a consequence of Avogadro's law).
Hence, the complete combustion reaction that has a ratio of 100 ml of gaseous hydrocarbon to 300 ml of oxygen, is that whose mole ratio is 1 mol hydrocarbon : 3 mol of oxygen.
Then, you must write the balanced chemical equations for the complete combustion of the four hydrocarbons in the list of choices, and conclude which has such mole ratio (1 mol hydrocarbon : 3 mol oxygen).
A complete combustion reaction of a hydrocarbon is the reaction with oxygen that produces CO₂ and H₂O, along with the release of heat and light.
a. C₂H₄:
C₂H₄ (g) + 3O₂ (g) → 2CO₂(g) + 2H₂O (g)Precisely, for this reaction the mole ratio is 1 mol C₂H₄: 2 mol O₂, hence, this is the right choice.
The following analysis just shows that the other options are not right.
b. C₂H₂:
2C₂H₂ (g) + 5O₂ (g) → 4CO₂(g) + 2H₂O (g)The mole ratio for this reaction is 2 mol C₂H₂ :5 mol O₂.
с. С₃Н₈
C₃H₈ (g) + 5O₂ (g) → 3CO₂(g) + 4H₂O (g)The mole ratio is 1 mol C₃H₈ : 5 mol O₂
d. C₂H₆
2C₂H₆ (g) +7 O₂ (g) → 4CO₂(g) + 6H₂O (g)The mole ratio is 2 mol C₂H₆ : 7 mol O₂

How many grams of AL are needed to completely react with 135g FE2O3
About 45.6 gAL are need to completely react with 135g FE2O3
To determine the mass of Al needed to react with 135 grams of Fe₂O₃, convert the mass of Fe₂O₃ to moles, use the stoichiometric ratio to find moles of Al needed, and then convert those moles to grams of Al to three significant figures.
The question is asking how many grams of aluminum (Al) are needed to completely react with 135 grams of iron(III) oxide (Fe2O3). This is a stoichiometry problem that requires using the balanced chemical equation:
Fe₂O₃(s) + 2Al(s) →2Fe(s) + Al₂O₃(s)
We start by converting the mass of Fe₂O₃ to moles using its molar mass:
1.0g Fe₂O₃ / 159.7 g/mol = moles of Fe₂O₃
Then we use the mole ratio from the balanced equation to convert from moles of Fe₂O₃ to moles of Al. The molar mass of Al is 27.0 g/mol. Finally, we convert moles of Al to grams using its molar mass to find the mass of Al needed for the reaction.
With the provided mass of 135g of Fe₂O₃, and the reaction stoichiometry, we can determine the mass of Al required which will be expressed to three significant figures.
