Repeat step 2 and 3 for the following equations:

A. 3N^2 +N^2 going to 2NH^3
B. CH^4+20^2 going to CO^2 + 2H^2O

A.

Step 2: Balance the atoms individually:
3N: 3 on reactant side, 6 on product side
H: 6 on reactant side, 6 on product side
Step 3: Write the balanced equation:
3N^2 + 6H^3 -> 2NH^3

B.
Step 2: Balance the atoms individually:
C: 1 on reactant side, 1 on product side
H: 4 on reactant side, 4 on product side
O: 2 on reactant side, 2 on product side
Step 3: Write the balanced equation:
CH^4 + 20^2 -> CO^2 + 2H^2O
