What is the chemical equation for calcium + phosphorus …

13/5/2014· Calcium + Phosphorous to produce Calcium Phosphide is an ionic synthesis reaction. Calcium has a charge of Ca^(+2).Phosphorous has a charge of P^-3. To bond these two ions together, their charges must be equal and opposite. Therefore we need 3 Ca^(+2) ions to balance with 2 P^-3 in order to balance their charges at 6 for the molecule Ca_3P_2. 3Ca + 2P -> Ca_3P_2 I hope this was …
