which compounds are reactants in the process of cellular respiration

A. C6H12O6 and O2

B. C6H12O6 and CO2

C.H2O and CO2

D. H2O and O2

Answer:

1) The rate of the overall reaction = Δ[N₂O]/Δt = 0.015 mol/L.s.

2) The rate of change for NO = - Δ[NO]/Δt = 3 Δ[N₂O]/Δt  = 0.045 mol/L.s.

Explanation:

3NO(g) → N₂O(g) + NO₂(g).

The rate of the reaction = -1/3 Δ[NO]/Δt = Δ[N₂O]/Δt = Δ[NO₂]/Δt.

Given that: Δ[N₂O]/Δt = 0.015 mol/L.s.

1) The rate of the overall reaction is?

The rate of the overall reaction = Δ[N₂O]/Δt = 0.015 mol/L.s.

2) The rate of change for NO is?

The rate of change for NO = - Δ[NO]/Δt.

∵ -1/3 Δ[NO]/Δt = Δ[N₂O]/Δt.

∴ The rate of change for NO = - Δ[NO]/Δt = 3 Δ[N₂O]/Δt = 3(0.015 mol/L.s) = 0.045 mol/L.s.

The overall reaction rate is 0.015 mol/L·s, and the rate of change for NO is -0.045 mol/L·s. This is based on the stoichiometric coefficients in the balanced equation 3 NO(g) → N₂O(g) + NO₂(g). For every mole of N₂O formed, 3 moles of NO are consumed.

To find the rate of the overall reaction and the rate of change for NO in the reaction 3 NO(g) → N₂O(g) + NO₂(g), we start with the given information that 0.015 mol/L of N₂O is being formed each second. This implies the rate of formation of N₂O is 0.015 mol/L·s.

The rate of the reaction can be expressed using the stoichiometric coefficients from the balanced equation. Since 3 moles of NO are consumed for every 1 mole of N₂O formed, the rate of the reaction in terms of N₂O formation is:

Rate of reaction = (1/1) × 0.015 mol/L·s = 0.015 mol/L·s

Next, for the rate of change of NO, we consider the stoichiometry of the reaction. For each mole of N₂O formed, 3 moles of NO are consumed. Thus, the rate of change for NO is:

Rate of change for NO = -3 × (rate of formation of N₂O)

This gives us:

Rate of change for NO = -3 × 0.015 mol/L·s = -0.045 mol/L·s

Answer:

B) Equilibrium is pushed towards the left in the equation

PbCl2 -> Pb+2 + 2Cl-

Explanation:

We have a saturated solution of PbCl2. It means the maximum amount of PbCl2 is dissolved in the solution. If we add sodium Chloride - NaCl, the solubility will be reduced.

NaCl will dissolve into the solution forming Na+ and Cl- ions. Cl- ions are common for the PbCl2 and NaCl. The effect of increasing Cl- ions due to the NaCl will reduce the solubility of PbCl2.

It means if we add Cl- ions or Pb+2 ions independent from the component apportioning them, the solubility will be reduced for the PbCl2, and the equilibrium will be pushed towards the left in the equation

PbCl2 -> Pb+2   + 2Cl-

Finally, we can conclude that the answer is B) Equilibrium is pushed towards the left in the equation:

PbCl2 -> Pb+2   + 2Cl-

Adding sodium chloride to a saturated solution of lead chloride reduce the solubility of PbVI2 because equilibrium is pushed towards the left in the equation PbCl2 → Pb+2 + 2Cl-. Therefore, option B is correct.

Under normal environmental circumstances, the inorganic compound lead(II) chloride is a white solid. It does not dissolve well in water. One of the most crucial lead-based reagents is lead(II) chloride. Additionally, it can be found naturally as the mineral cotunnite.

Lead nitrate is reacted with sodium chloride or hydrochloric acid to produce lead(II) chloride. It can also be produced by mixing hydrochloric acid with lead(IV) oxide. Lead and chlorine can also be reacted to create it.

Due to the additional Cl-, the reaction quotient for PbCl2 exceeds the equilibrium constant. As a result, this causes precipitation and lowers the reaction's present solubility, shifting the reaction to the left in the direction of equilibrium. Overall, adding sodium chloride causes the reaction's solubility to decrease.

Thus, option B is correct.

The correct answer is B.

Fructose O_O

Fructose is the sweetest of the naturally-occurring sugars.

Fructose is the sweetest of all natural sugars, found in fruits, vegetables, honey, and high fructose corn syrup. It is used by plants to attract insects and animals, facilitating pollination and seed dispersal. Sucrose and lactose are other natural sugars with differing sweetness levels and roles.

The question pertains to the identification of the sweetest of all natural sugars. The answer is fructose, which is a monosaccharide that surpasses other sugars in sweetness. Naturally occurring in fruits, vegetables, honey, and high fructose corn syrup, fructose plays a significant role in the diet and the ecosystem.

Sugars like sucrose and lactose are also prevalent in our diets, coming from sources such as sugar cane, sugar beets, and dairy, respectively. Sucrose, commonly known as table sugar, and lactose, known as milk sugar, have their unique roles and sweetness profiles. However, fructose is distinguished by its exceptional sweetness and is employed by plants as a strategy to attract insects for pollination and animals for seed dispersal, creating a beneficial relationship between fauna and flora.

Understanding the types of naturally occurring sugars and their sources can contribute significantly to our knowledge of diet, nutrition, and ecosystem interdependencies.

The best test would be doing a double-blind test between the person who is receiving the medicine so that they don't know if they received a placebo or not and the person giving the medicine does not know if the participant is receiving a placebo or not.

However, a placebo test can simply be done. This is where the patient received a medicine that does not have any medicinal effects and see if the person sleeps better. If they say they did, they have fallen under the placebo effect.

The increase in reaction rate caused by raising the temperature or pressure is explained by collision theory, which states that reactions occur due to collisions with enough energy and proper orientation. Higher temperatures mean more energetic collisions, and increasing pressure leads to a higher frequency of collisions, both contributing to a faster reaction rate.

The increase in reaction rate due to raising the temperature or raising the pressure of a system can be explained by d) collision theory. Collision theory posits that chemical reactions occur when reactants collide with sufficient energy and correct orientation. An increase in temperature leads to a greater number of collisions because particles move faster and have more energy, which can be converted into activation energy in a collision. Furthermore, the collisions are more forceful, making it more likely for the reactants to overcome the activation energy barrier and form products, hence increasing the rate of reaction.

Similarly, increasing the pressure in a system typically means more particles are forced into a smaller volume, thus increasing the frequency of collisions. This is especially true for reactions involving gases, where an increase in pressure often corresponds to an increase in concentration, further facilitating more frequent collisions and potentially a faster reaction rate.

Other than to say that I see why you are having trouble, I think you could use either.

Having said that, the blue is far more pronounced going from 7 to 9. Seven is more of a dirty blue at 7. It is sky blue at 9. I would pick that.

When you look up it's pH it is given as 7.6 which is about as slightly basic as you can get. At that point it starts to turn blue.

Methyl Red is really weird stuff.

It is red under pH = 4.4 which definitely acidic and yellow above 6.2. It is orange in between.

I would still go with Bromothymol blue, but I'm betting that either could be used.

I hope this is a discussion question, because if you want my honest opinion, it's too close to call.

Answer:

Bromthymol Blue

Step-by-step explanation:

You want to choose an indicator that changes colour at the right pH.

In this case, let's say slightly basic means pH ≈ 8.  

Methyl Red

From the pictures, it looks like pH 6 and pH 8 would have similar colours, and it would be difficult to distinguish them. The solution could be slightly acidic or slightly basic.

Bromthymol Blue

A solution with pH 8 would have a definite blue-green colour, which indicates that the solution is basic with no ambiguity.

I vote for Bromthymol Blue.

The answer is a.  Melting the solid.

Using stoichiometry and the balanced chemical equation provided, the first row of the table is completed with 3 moles of SiO₂, 9 moles of C, 3 moles of SiC, and 6 moles of CO.

The student's question involves completing a table for a chemical reaction with known mole ratios. The balanced equation is SiO₂(s) + 3C(s) ightarrow SiC(s) + 2CO(g). To complete the table for the first row where 9 moles of carbon (C) are provided, we apply stoichiometry based on the balanced equation:

For every 3 moles of C used, 1 mole of SiO₂ is required, so 9 moles of C would need 9/3 = 3 moles of SiO₂.

For every 3 moles of C, 1 mole of SiC is produced, so 9 moles of C will yield 9/3 = 3 moles of SiC.

Each mole of SiO₂ reacts to form 2 moles of CO, so for 3 moles of SiO₂, we will get 3 × 2 = 6 moles of CO.

When a soft drink starts to warm to room temperature, the air at the top of the can or bottle starts to sink into the water creating more bubbles and/or fizz. The space at the top of the can or bottle starts to shrink up.

Answer:

As the refrigerant begins to warm up to room temperature, the air inside the bottle that is between the refrigerant and the bottle cap begins to slowly come down. As you might already imagine, air in contact with the liquid can generate bubbles, and this is what happens when the air in the bottle starts to drop as the soda heats up.

Explanation:

You have seen that at room temperature it is common for soda to overflow bubbles. This is because the air inside the soda bottle begins to come down and when it comes in contact with the liquid causes a lot of bubbles and can even make the soda overflow.

In covalent bonding, both atoms are trying to attract electrons--the same electrons. Thus, the electrons are shared tightly between the atoms.

The force of attraction that each atom exerts on the shared electrons is what holds the two atoms together.

Answer: Option (a) is the correct answer.

Explanation:

A covalent bond is defined as the bond which is formed due to sharing of electrons.

For example, a carbon atom has 4 valence electrons and a hydrogen atom has 1 valence electron.

So, when a carbon atom chemically combines with a hydrogen atom then sharing of electrons take place between the two and it results in the formation of a methane molecule.

        [tex]C + 2H_{2} \rightarrow CH_{4}[/tex]

Whereas a bond in which transfer of electrons take place from one atom to another is known as an ionic bond.

For example, [tex]2Na + Cl_{2} \rightarrow 2NaCl[/tex]

Thus, we can conclude that in a covalent bond electrons that are shared between atoms holds atoms together.

6. Heat of combustion

M_r:     46.1

        C₂H₅OH + 3O₂ ⟶ 2CO₂ + 3H₂O; ΔH = -1.37 × 10³ kJ

m/g:     17.2

n =17.2/46.1 = 0.3731 mol

q = nΔH = 0.3731 × (-1.37 × 10³) = -511 kJ = -5.11 × 10² kJ

The reaction releases 5.11 × 10² kJ of heat.

The answer is c because some plants can die from too much water

Answer: C. amount of rainfall

Explanation:

The amount of rainfall is an abiotic factor (non-living) which is necessary for the growth of plants. The water from the rainfall is necessary for the large scale natural irrigation of an agricultural land, forest, meadow or grassland. The water enters into the soil and through the roots the water is absorbed by the plants.

If a region receives very low annual rainfall then the region may experience desertification. The soil will become compact and dry which cannot support the growth of plants.

If a region receives adequate rainfall then the soil will hold water it will remain fertile to support the diversity of plants.

4x^3  = 1.4 x 10^-5

         = 0.015 M

molar solubility = 0.015 M

But;

[Ag+]= 2x

Hence; silver ion concentration is

= 2 x 0.015 M

= 0.030 M

Final answer:

The silver ion concentration in a saturated solution of silver(I) sulfate with a Ksp of 1.4 × 10–5 is approximately 1.52 × 10–2 M.

Explanation:

To calculate the silver ion concentration in a saturated solution of silver(I) sulfate, first we must understand that the dissolution of silver sulfate, Ag2SO4, in water can be represented by the equation:

Ag2SO4(s) ⇌ 2Ag+(aq) + SO42-(aq)

Applying the solubility product constant (Ksp), the equilibrium constant expression for this dissolution can be written as:

Ksp = [Ag+]2[SO42-]

Given that the Ksp for silver(I) sulfate is 1.4 × 10–5, and assuming that the concentrations of silver and sulfate ions are equal to their stoichiometric coefficients, we can set up the equation:

1.4 × 10–5 = x2[SO42-]

Where x is the molar concentration of Ag+. Since there are two moles of Ag+ for every mole of Ag2SO4 that dissolves, we can express the sulfate ion concentration as [SO42-] = x, which simplifies the equation to:

1.4 × 10–5 = (2x)2x

Now we can solve for x:

1.4 × 10–5 = 4x3

x3 = 3.5 × 10–6

x ≈ 1.52 × 10–2 M

So the concentration of silver ions, [Ag+], in a saturated solution of silver(I) sulfate is approximately 1.52 × 10–2 M.

the answer is c- thunderstorms

Magnetism is a force that certain objects called 'magnetic' objects can exert on each other without physically touching. It can push or pull things and is described by the arrangement of magnetic fields.

Magnetism is a force that certain kinds of objects, which are called 'magnetic' objects, can exert on each other without physically touching. A magnetic object is surrounded by a magnetic 'field' that gets weaker as one moves further away from the object. This force can push or pull other objects. For example, when you bring two magnets close to each other, they can either attract or repel each other based on the arrangement of their magnetic fields.
