To complete the following chemical equation, what coefficients must be added? cu(oh)2 + h3po4 yields cu3 (po4)2 + h2o

3, 2, 1, 6

Explanation:

The unbalanced combustion reaction is shown below as:-

On the left hand side,  

There are 1 copper atom and 1 phosphorus atom

On the right hand side,  

There are 3 copper atoms and 2 phosphorus atoms

Thus,  

Left side, must be multiplied by 3 and by 2 so to balance copper phosphorus atoms.

Left side, 12 H, so must be multiplied by 6.

Thus, the balanced reaction is:-
