Answer #1

The unbalanced chemical reaction is

Sn(s) + P(s) ------ > Sn3P4(s)

There are 3 Sn atoms on product side in Sn3P4(s), but only 1 Sn atom on reactant side. Hence we need to multiply the Sn(s) on reactant side by 3 to balance Sn atom.

Also there are 4 P atoms on product side in Sn3P4(s), but only 1 P atom on reactant side. Hence we need to multiply the P(s) on reactant side by 4 to balance P atom.

Now the final balanced reaction is

3 Sn(s) + 4 P(s) ------- > Sn3P4(s) (answer)
