Balance the equation and identify the type of reaction for? p4 (s) + ? ca (s) →? ca3p2 (s).

There are different kinds of reactions. To name some, these are the synthesis reaction, decomposition reaction, single-replacement reaction, double-replacement reaction, combustion reaction, redox reaction, etc. For this type of reaction involving two reactants to yield only one product, this is a synthesis reaction.

P₄ (s) + 6 Ca (s) - - > 2 Ca₃P₂ (s)
