Stoichiometry

Front

What is Stoichiometry?

Back

The branch of chemistry that deals with the calculation of reactants and products in chemical reactions.

Front

What is a Limiting Reagent?

Back

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

Front

How do you determine the Limiting Reagent in a reaction?

Back

By calculating the amount of product each reactant can produce and identifying the one that produces the least.

Front

What is the Mole Ratio?

Back

The ratio of moles of one substance to the moles of another substance in a balanced chemical equation.

Front

In the reaction 2H₂ + O₂ → 2H₂O, how many moles of water are produced from 4 moles of hydrogen?

Back

4 moles of water.

Front

What is the purpose of a balanced chemical equation?

Back

To ensure that the number of atoms for each element is conserved in a chemical reaction.

Front

What is the formula to calculate moles?

Back

Moles = Mass (g) / Molar Mass (g/mol).

Front

If you have 10 moles of A and 5 moles of B in the reaction A + 2B → C, which is the limiting reagent?

Back

B is the limiting reagent.

Front

What is the significance of the excess reagent?

Back

The reactant that remains after the limiting reagent is completely consumed.

Front

How do you convert grams to moles?

Back

Use the formula: Moles = Mass (g) / Molar Mass (g/mol).
