What is stoichiometry?

Back

Stoichiometry is the branch of chemistry that deals with the calculation of reactants and products in chemical reactions based on the balanced equations.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, ensuring the law of conservation of mass is followed.

Front

What are coefficients in a chemical equation?

Back

Coefficients are the numbers placed in front of the compounds in a chemical equation that indicate the relative amounts of each substance involved in the reaction.

Front

How do you determine the mole ratio from a balanced equation?

Back

The mole ratio is determined by the coefficients of the balanced equation, which indicate the proportion of moles of each reactant and product.

Front

What is the molar mass of a substance?

Back

The molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).

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 formed.

Front

How do you calculate the mass of a product formed in a reaction?

Back

To calculate the mass of a product, use the mole ratio from the balanced equation and the molar mass of the product.

Front

What is the significance of the number 22.4 in stoichiometry?

Back

22.4 liters is the volume occupied by one mole of an ideal gas at standard temperature and pressure (STP).

Front

What is the difference between a reactant and a product?

Back

Reactants are the starting materials in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance (in grams) by its molar mass (in g/mol).
