Proof of the experiment and what happened during the experiment.
<em>Nitric acid, </em><em>is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water.</em>
There are THREE different elements and a total of FIVE atoms in nitric acid.
<em>The formula for nitric acid is</em><em> </em><em><u>HNO3.</u></em><em> This means there is one atom of hydrogen, one atom of nitrogen, and three atoms of oxygen in one molecule of nitric acid.</em>
<em>So, Thus, your answer will be </em><u><em>FIVE</em></u><em> if you're counting the molecules but if you are counting the elements then it is </em><u><em>THREE.</em></u>
