Question

Complete them with correct formulas
Then balance them

Answer 1

1. 2Ca + N
`_(2)` → 2CaN

2. 4Li + O
`_(2)` → 2Li
`_(2)`O

3. 2KCl + BaF
`_2` → 2KF + BaCl
`_2`

4. CH
`_4` + 2O
`_2` → CO
`_2` + 2H
`_2`O

Be sure to balance the number of atoms on both sides of each equation only by adding coefficients to the compounds!!!! Those without a coefficient are meant to have a coefficient of 1.
