Question

Blank Na2CO3 + blank Ag3P --> blank Na3P + blank Ag2CO3

Answer 1

Answer: __3__Na2CO3 + __2__Ag3P → __2__Na3P + __3__Ag2CO3

Explanation:

In balancing equations you need to make sure the number of atoms before the reaction should be equal to the number of atoms after the reaction.

Before the reaction: We had 6Na, 9CO, 6Ag and 2p

After the reaction: We have 6Na, 9CO, 6Ag and 2p

And now we are sure that atoms before the reaction are equal to atoms after the reaction
