Question

How does phosporus reacts with calcium?​

Answer 1

Answer:

Calcium + Phosphorous to produce Calcium Phosphide is an ionic synthesis reaction. Calcium has a charge of Ca+2 . ... 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 Ca3P2 .
