Identify the following as True or False? 1. The limiting reactant is the reactant that is completely consumed in a chemical reaction.
2. The reactant in excess is any reactant that occurs in a quantity greater than that is required to completely react with the limiting reactant.
3. The amount of product can be calculated based on the amount of limiting reactant.

Answers

Answer 1

Answer:

Answer :

(1) The limiting reactant is the reactant that is completely consumed in a chemical reaction. → True

(2) The reactant in excess is any reactant that occurs in a quantity greater than that is required to completely react with the limiting reactant. → True

(3) The amount of product can be calculated based on the amount of limiting reactant. → True

Explanation :

Excess reagent : It is defined as the reactants not completely used up in the reaction. The given moles are more than the required moles.

Limiting reagent : It is defined as the reactants completely used up in the reaction. The given moles are less than the required moles.

Theoretical yield : It is calculated from the amount of the limiting reagent present in the reaction.

Actual yield : It is experimentally determined.

All the given statements are true.

Answer 2

Answer:

Final answer:

The limiting reactant is the reactant that is completely consumed in a chemical reaction. The reactant in excess is any reactant that occurs in a quantity greater than that required to completely react with the limiting reactant. The amount of product can be calculated based on the amount of limiting reactant.

Explanation:

1. True. The limiting reactant is the reactant that is completely consumed in a chemical reaction. It determines the amount of product that can be formed.

2. True. The reactant in excess is any reactant that occurs in a quantity greater than that required to completely react with the limiting reactant.

3. True. The amount of product can be calculated based on the amount of limiting reactant using stoichiometry.

In the reaction Mg (s) + 2HCl (aq) H2 (g) + MgCl2 (aq), how many grams of hydrogen gas will be produced from 125.0 milliliters of a 6.0 M HCl in an excess of Mg?

Answers

The balanced reaction is:

Mg (s) + 2HCl (aq) = H2 (g) + MgCl2 (aq)

We are given the amount of reactants to be reacted. This will be the starting point of the calculations.

.125 L HCl solution (6.0 mol HCl / L solution) ( 1 mol H2 / 2 mol HCl ) ( 2.02 g H2 / 1 mol H2 ) = 0.76 g H2

Which law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant?

Answers

Answer: Avogadro's Law states that volume is directly proportional to the oles of the gas.

Explanation: Expression fro ideal gas equation:

$PV=nRT$

This law has arrived from the combination of four laws:

1) Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto (1)/(V)$ (At constant temperature and number of moles)

2) Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles)

3) Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

$P\propto T$ (At constant volume and number of moles)

4) Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

$V\propto n$ (At constant temperature and pressure)

Hence, the correct answer is Avogadro's Law.

Which of the following objects has the highest average kinetic energy? and whyAn ice cube, A pool of cool water, A cup of warm water, A cup of boiling water

Answers

Answer:

A cup of boiling water.

Explanation:

Due to their mobility, particles in a substance contain kinetic energy. The average kinetic energy of the particles increases with temperature.

Since hot water has the highest temperature of the available possibilities in this situation, it has the highest average kinetic energy. Compared to particles in icy water, warm water, or room temperature water, those in hot water are moving more quickly and possess more energy.

For instance, when hot water is compared to frozen water, the particles in the hot water are moving more quickly due to the higher temperature. The lower temperature of ice water causes the particles to move more slowly. A difference in average kinetic energy results from this difference in velocity.
