Question

Which of the following equations is not balanced?

N2 + 3H2 → 2NH3

A. N2 + 3H2 → 2NH3

B. MgI2 + Br2 → MgBr2 + I2

C. KClO3 → KCl + O2

D.HCl + NaOH → NaCl + H2O

Answer 1

Answer: C) KClO3 → KCl + O2

Step-by-step explanation:

the equation has an unequal amount of oxygen.

you can confirm because all the other equations are balanced so the answer is c

Answer 2

`KClO_(3)\rightarrow KCl+O_(2)`

(C) is correct option

Step-by-step explanation:

Balanced equation :

In balanced equation, The number of atoms of each element in product side equal to the number of atoms of each element in reactant side.

The equation is not balanced in option C.

`KClO_(3)\rightarrow KCl+O_(2)`

In this equation, The number of oxygen element in product side is not equal to the number of oxygen element in reactant side.

All equations are balanced.
