Question

To complete the following chemical equation, what coefficients must be added? _____ Cu(OH)2 + _____ H3PO4 yields _____ Cu3 (PO4)2 + _____ H2O

Answer 1

Answer:

3, 2, 1, 6

Explanation:

The unbalanced combustion reaction is shown below as:-

$Cu(OH)_2+H_3PO_4\rightarrow Cu_3(PO_4)_2+H_2O$

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, $Cu(OH)_2$ must be multiplied by 3 and $H_3PO_4$ by 2 so to balance copper phosphorus atoms.

$3Cu(OH)_2+2H_3PO_4\rightarrow Cu_3(PO_4)_2+H_2O$

Left side, 12 H, so $H_2O$ must be multiplied by 6.

Thus, the balanced reaction is:-

$3Cu(OH)_2+2H_3PO_4\rightarrow Cu_3(PO_4)_2+6H_2O$
