mole to mole stoichiometry

Front

What is the purpose of stoichiometry in chemistry?

Back

To predict the quantities of reactants and products involved in chemical reactions.

Front

In the reaction 2H2 + O2 → 2H2O, how many moles of water can be produced from 6.5 moles of H2?

Back

6.5 moles of water.

Front

What is mole to mole stoichiometry?

Back

A method used in chemistry to calculate the amount of reactants and products in a chemical reaction based on the balanced chemical equation.

Front

What is a balanced chemical equation?

Back

A chemical equation that has the same number of atoms of each element on both sides, ensuring the law of conservation of mass is followed.

Front

What is the relationship between moles and mass?

Back

Moles can be converted to mass using the formula: mass = moles × molar mass.

Front

What is the molar mass of water (H2O)?

Back

18 g/mol.

Front

How do you calculate the number of moles from mass?

Back

Moles = mass / molar mass.

Front

What is the law of conservation of mass?

Back

Mass is neither created nor destroyed in a chemical reaction.

Front

If 4 moles of H2 react with O2, how many moles of H2O are produced?

Back

4 moles of H2O.

Front

What is the stoichiometric coefficient in a balanced equation?

Back

The number in front of a compound that indicates the ratio of moles in a reaction.
