Answer:
Reactants: Na = 2, O = 2, H = 2, Cu = 1, Cl = 2;
Products: Na = 2, Cl = 2, Cu = 1, O = 2, H = 2
Explanation:
NaOH + CuCL2 —> NaCl + Cu(OH)2
The balanced equation can be achieved by doing the following:
There are 2 oxygen and 2 hydrogen atom on the right side. This is balanced by putting 2 in front of NaOH as shown below:
2NaOH + CuCL2 —> NaCl + Cu(OH)2
This makes Na to be unbalanced. Now to balance Na, put 2 in front of NaCl as illustrated below
2NaOH + CuCL2 —> 2NaCl + Cu(OH)2
Now the equation is balanced.
Reactants: Na = 2, O = 2, H = 2, Cu = 1, Cl = 2
Products: Na = 2, Cl = 2, Cu = 1, O = 2, H = 2
