Stoichiometry Intro Exit Ticket

Front

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 conservation of mass.

Front

What is a mole in chemistry?

Back

A mole is a unit of measurement used to express amounts of a chemical substance, defined as exactly 6.022 x 10^23 particles (atoms, molecules, etc.).

Front

How do you convert grams to moles?

Back

To convert grams to moles, use the formula: Moles = Mass (g) / Molar Mass (g/mol).

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, reflecting the conservation of mass.

Front

What is the purpose of coefficients in a balanced equation?

Back

Coefficients indicate the relative amounts of reactants and products involved in a chemical reaction.

Front

How do you find the molar mass of a compound?

Back

To find the molar mass, sum the atomic masses of all the atoms in the compound's formula.

Front

What is a mole ratio?

Back

A mole ratio is a conversion factor derived from the coefficients of a balanced chemical equation, used to relate the amounts of reactants and products.

Front

What is the first step in solving a stoichiometry problem?

Back

The first step is to write a balanced chemical equation for the reaction.

Front

How do you determine the limiting reactant in a reaction?

Back

The limiting reactant is the reactant that is completely consumed first, limiting the amount of product formed.

Front

What is the significance of the subscripts in a chemical formula?

Back

Subscripts indicate the number of atoms of each element in a molecule of the compound.
