Electrolytes are substances that dissociates into ions when dissolved into water. These substances are known to conduct electricity because of the mobility of the positive and negative ions. The electrolytes are divided into acids, bases, or salts.
There are 9 H atoms in one molecule, so hydrogen is present in the greatest proportion by number of particles;
The ratio by particles is C:H:O:N = 8:9:2:1.

C
Explanation:
For an organism scientific names the first part is the genus and the second is the species
The changes in matter/energy can be classified as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
<h3>What are physical, chemical and nuclear changes?</h3>
Matter and energy undergo physical, chemical and nuclear changes.
Physical changes are changes in which no new product is formed.
Chemical changes are changes in which no new product is formed.
Nuclear changes are changes in which no new product is formed.
Examples of each of the given changes is as follows:
- Physical changes - Crystallizing salt from seawater
- Chemical changes - ripening fruit
- Nuclear changes - production of elements in the stars
Therefore, matter/energy undergo changes.
