Question

The polyatomic nitrate ion (NO3−) is present in both the products and the reactants of the chemical equation shown below.

Answer 1

Answer:

There is one nitrate ion in the products, and two in the reactants of this equation.

Explanation:

1: We know a nitrate ion has the formula $NO_{3}^{-$ , so we just need to count how many of them are on each side of the equation.

2: To find how many are in the reactants of the equation, you look at the left hand side (before the arrow). You can see the section $(NO_{3} )_{2}$ , which shows that there are two nitrate ions in the reactant side (as seen by the little 2).

3: To find how many are on the products side, you do the same thing - this time there is only one $NO_{3}^{-$ in the lithium nitrate.

So, there is one nitrate ion in the products, and two in the reactants of this equation.
