Question

2. What is the difference between 2H and H,?
3. How is chemically pure water obtained from the water we use for cooking and drinking?​

Answer 1

Explanation:

2 ) H2 is Molecular hydrogen. ... A subscript also denotes how many of a particular atom is in a molecule, thus H2 has two hydrogens. 2H, on the other hand, denotes two moles of elemental hydrogen.

3 ) Distilled water is produced by a process of distillation. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces very pure water.
