Question

Which of the following equations is not balanced?

N 2 + 3H 2 → 2NH 3
MgI 2 + Br 2 → MgBr 2 + I 2
KClO 3 → KCl + O 2
HCl + NaOH → NaCl + H 2 O

Chemistry&Physics is not my best subject.. Help? Thanks<3

Answer 1

3rd equation is not balanced
2KClO3→2KCl+3O2
this equation is right (balanced)

Answer 2

1st is balanced
2nd is balanced
3rd is not balanced
4th is balanced

therefore the answer is 3rd one-
KClO 3 → KCl + O 2
