How do I do 2 and 4 I don’t understand how to solve it

1 answer:

7 0

For question two, you figure out the amount of sodium atoms on the left and right side and the amount of oxygen atoms on the left and right side

So for two it would be 4, 1, 2

For question four, you figure out the amount of atoms on each side

So for four it would be 1, 2, 1, 2
