Question

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

Answer 1

3, 2, 1, and 6

Step-by-step explanation:

Answer 2

The numerical coefficients are needed in order to complete the chemical reaction by balancing. Balancing is done by equating the number of atoms/elements on both sides of the chemical reaction. In this item, the balanced chemical reaction is,

3Ca(OH)2 + 2H3PO3 --> Ca3(PO3)2 + 6H2O

The numerical coefficients are 3, 2, 1, and 6.
