Question

balance the following equation:

___ni(clo_{3})_{2} \to ___nicl_{2} + ___o_{2}

when the equation is properly balanced, the correct coefficients are, respectively

Explanation:

Step1: Balance chlorine atoms

In \(Ni(ClO_3)_2\), there are 2 chlorine atoms. In \(NiCl_2\), there are 2 chlorine atoms. So, the coefficient for \(NiCl_2\) is 1 when the coefficient for \(Ni(ClO_3)_2\) is 1.

Step2: Balance oxygen atoms

In \(Ni(ClO_3)_2\), there are \(3\times2 = 6\) oxygen atoms. Let the coefficient of \(O_2\) be \(x\). Then \(2x=6\), so \(x = 3\).

Answer:

1, 1, 3
