Front

What is a limiting reactant?

Back

The limiting reactant is the substance that is completely consumed in a chemical reaction, limiting the amount of product that can be formed.

Front

How do you identify the limiting reactant in a reaction?

Back

To identify the limiting reactant, compare the mole ratio of the reactants used in the balanced equation to the moles available. The reactant that produces the least amount of product is the limiting reactant.

Front

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, based on stoichiometric calculations.

Front

What is the formula for calculating the theoretical yield?

Back

Theoretical Yield = (moles of limiting reactant) x (molar mass of product) / (mole ratio from balanced equation).

Front

What is stoichiometry?

Back

Stoichiometry is the calculation of reactants and products in chemical reactions based on the conservation of mass.

Front

What is the balanced equation for the reaction of hydrogen and oxygen to form water?

Back

2 H₂ + O₂ → 2 H₂O.

Front

In the reaction 4NH₃ + 6NO → 5N₂ + 6H₂O, how many moles of N₂ can be produced from 10 moles of NH₃?

Back

8 moles of N₂ can be produced from 10 moles of NH₃.

Front

What is the molar mass of SO₂?

Back

The molar mass of SO₂ (sulfur dioxide) is approximately 64.07 g/mol.

Front

If 16.2 g of SO₂ reacts with 13.7 g of PCl₅, how do you calculate the theoretical yield of SOCl₂?

Back

Convert grams of SO₂ and PCl₅ to moles, determine the limiting reactant, and then use stoichiometry to find the theoretical yield of SOCl₂.

Front

What is the significance of a balanced chemical equation?

Back

A balanced chemical equation ensures that the number of atoms for each element is conserved, reflecting the law of conservation of mass.
