The change is thermal energy to chemical energy. Sugar contains a lot of chemical potential energy which is why living things use it as a source of energy. The process of photo synthesis takes light from the sun to convert carbon dioxide and water into sugar and oxygen. That process is basically turning the thermal energy from the light into chemical energy in the sugar.

A formula unit of the nitrate salt of Q is Q(NO3)2.
<h3>What is IUPAC nomenclature?</h3>
The IUPAC nomenclature was put together by the international Union of Pure and applied chemistry in order to have a uniform way of naming compounds.
We shall now find the names of the compounds;
1) Na* and HPO4²- ; sodium hydrogen tetraoxophoshate V
2) Potassium cation and cyanide anion ; Potassium cyanide
3) Calcium cation and hypochlorite anion; Calcium oxochlorate I
Knowing that the valency of NO3^- is one and that the compound formed between Q and CO3²- has the formula QCO3 we can conclude that a formula unit of its nitrate salt is Q(NO3)2.
