WebSep 27, 2016 · 1 Answer. Sorted by: 4. 2 Z n ( N O X 3) X 2 can be interpreted differently, depending on the context. The '2' outside of the parenthesis could either refer to two molecules or two moles of substance. In either case, the chemical formula tells you the same thing: that there are two units of N O X 3 X − for every unit Z n X 2 +. WebThere's 2 on the left and 1 on the right, so we need to change the coefficient of NH3 to 2. Now we have. N2 + H2 -> 2NH3. Total the atoms up again: On the left there is 2 N and 2 H still. On the right there is 2 N and 6 H now. So now all we need to do is make the left side have 6 H in total.
