Mg + P4--> Mg3P2

Magnesium will react with phosphorus to form magnesium phosphide

Respuesta :

6Mg + P4 --> 2Mg3P2

I first balanced the Phosphorous on the right side to match the left. So by multiplying the right side equation by two we then received 4 Phosphorous. But that left us with 2 x 3 Magnesium on the right side. So to balance we added 6 to the left.
