How to Balance Lithium + Nitrogen gas → Lithium nitride

How to Balance: Li + N2 → Li3N

Type of Chemical Reaction: This is a combination reaction.

Word Equation: Lithium + Nitrogen gas → Lithium nitride

Balancing Strategies: In this combination reaction (also called synthesis) the Li and N2 are combining to form Li3N, Lithium Nitride.

Start by balancing the Nitrogen atoms first since the Li atom is a single element.

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.
