The amount of chemical energy a substance has is influenced by its structure and the bond the substance has.
Some bond is release energy when broken, other bond need some energy to break. The structure will also influence the chemical energy.
One of substance with high chemical energy is adenosine triphosphate which was used as energy source in a living organism. The phosphate bond in this molecule worth about 30.5 kJ/moles
For this reaction, the reactants are nitrogen dioxide, oxygen and water while the product would be nitric acid. The chemical equation would be written as:
NO2(g) + O2(g) + H2O(l) --> HNO3(aq)
This can be a complete equation when the elements are balanced in each side.
4NO2(g) + O2(g) + 2<span>H2O(l) --> 4HNO3(aq)</span>
Answer:
You're answer is B.
Explanation:
Covalent Bonds share a negative and positive ion.
Sodium/natrium is a metal from first column group so it should have one 1+ charge. Phosphate ion has 3- charge. That is why there 3 natrium ion for 1 phosphate ion when this molecule is dissolved in water. The ion formula would be:
(Na)
(PO
) ==> 3 Na
+ PO
