Front

Define stoichiometry.

Back

Stoichiometry is 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 that measures the amount of substance, defined as exactly 6.022 x 10^23 particles (atoms, molecules, etc.).

Front

Explain the concept of a mole ratio.

Back

A mole ratio is a ratio that relates the amounts in moles of any two compounds involved in a chemical reaction.

Front

What is the purpose of balancing a chemical equation?

Back

Balancing a chemical equation ensures that the same number of each type of atom appears on both sides of the equation, reflecting the conservation of mass.

Front

How do you determine the coefficients in a balanced chemical equation?

Back

Coefficients are determined by adjusting the numbers in front of the compounds to ensure that the number of atoms for each element is equal on both sides.
