How to Balance Lithium + Oxygen gas → Lithium oxide

How to Balance: Li + O2 → Li2O

Type of Chemical Reaction: This is a combination reaction.

Word Equation: Lithium + Oxygen gas → Lithium oxide

Balancing Strategies: In this combination reaction we have the lithium coming together with the oxygen gas to form within oxide.

To balance the equation you first need to get the oxygen atoms to be equal on both sides of the equation.

About Balancing Chemical Equations

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.
Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
