what is the oxidation number for n in the compound nh3? (recall that h usually has an oxidation number of +1.) -3 -1 0 +3

what is the oxidation number for n in the compound nh3? (recall that h usually has an oxidation number of +1.) -3 -1 0 +3

Answer

Answer:

A. -3

Explanation:

Step1: Set up the equation

Let the oxidation number of N be (x). In (NH_3), there are 3 H atoms each with an oxidation number of +1. The sum of oxidation - numbers in a neutral compound is 0. So the equation is (x + 3\times(+1)=0).

Step2: Solve the equation

[ \begin{align*} x+3&=0\ x&=- 3 \end{align*} ]
