Balancing Chemical Equations

Front

What role do coefficients play in balancing chemical equations?

Back

They represent the number of molecules of each substance.

Front

What should be true for all elements in a balanced chemical equation?

Back

They should be equal and as simplified as possible.

Front

What does balancing a chemical equation involve?

Back

Adding coefficients to ensure the number of atoms of each element is equal on both sides.

Front

What is meant by ‘balancing’ in the context of chemical equations?

Back

Ensuring the number of atoms for each element is the same on both sides of the equation.

Front

What is typically the first element balanced in a chemical equation?

Back

The element with the least atoms.

Front

What is a chemical equation?

Back

A representation of a chemical reaction using symbols and formulas.

Front

What are reactants in a chemical equation?

Back

Substances that undergo a chemical change in a reaction.

Front

What are products in a chemical equation?

Back

Substances that are formed as a result of a chemical reaction.

Front

What does it mean for a chemical equation to be balanced?

Back

The number of atoms of each element is the same on both sides of the equation.

Front

Why is it important to balance chemical equations?

Back

To obey the law of conservation of mass, which states that matter cannot be created or destroyed.
