what is the oxidation number for n in the compound nh₃? (recall that h usually has an oxidation number of +1.)\n-3\n-1\n0\n+3

Answer

Explanation:

Step1: Set up oxidation - number equation

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

Step2: Solve the equation for (x)

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

Answer:

A. -3
