Question

Can someone help me balance these chemical equations?

1. CuF2 + Mg ---------> MgF2 + Cu3
2. Na + H2O ----------> NaOH + H2
3. KBr + Cl2 ------------> KCl + Br2

Answer 1

1) 3CuF2 + 3Mg -> 3MgF2 + Cu3

2)2Na + 2H2O ->2NaOH + H2

3) 2KBr + Cl2 ->2KCl + Br2

Answer 2

Step-by-step explanation:

(1) CuF2+Mg-------->MgF2+Cu

(2) 2Na+2H2O --------> 2NaOH+H2

(3) 2KBr+Cl2-------->2KCl+Br2
