Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means ensuring that the number of atoms for each element is the same on both sides of the equation.

Front

What is the significance of the coefficients in a balanced equation?

Back

Coefficients indicate the relative number of moles of each substance involved in the reaction.

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance by its molar mass.
