To balance the reaction below, what would be the coefficients needed?

_Ca(0H)2+_H3(P04) ->_Ca3(P04)2+_H(0H)

A. 1,1,2,3
B. 1,2,1,5
C. 3,2,1,3
D. 3,2,1,6

1 answer

The balanced reaction would be:

3Ca(OH)2 + 2H3PO4 -> Ca3(PO4)2 + 6H2O

Therefore, the coefficients needed are 3, 2, 1, 6.

The correct answer is D. 3, 2, 1, 6.
