Question

To complete the following chemical equation, what coefficients must be added? _____ Ca(OH)2 + _____ H3PO3 yields _____ Ca3 (PO3)2 + _____ H2O

Answer 1

this is a neutralization reaction where calcium hydroxide and phosphoric acid are reactants whereas calcium phosphate and water are the products. any chemical reaction must be balanced for it to be considered correct. to balance this reaction we should put coefficients as follows 3Ca(OH)2+2H3PO3→Ca3(PO3)2+6H2O. this reaction is balanced since we 3
