Balancing Li + N2 → Li3N

Balancing Main     |   Big List of Equations     |   Breslyn.org

How to Balance:

Li + N2 → Li3N

Word equation: Lithium + Nitrogen gas → Lithium nitride

Type of Chemical Reaction: For this reaction we have a combination reaction.

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.

For a complete explanation, watch:

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.
