Question

Section A
What ar ions? What are its two types?
Find the ratio by mass of the elements present in the molecule of hydrogen sulphide H,8).
Given that, atomic mass S = 32, H = 1.​

Answer 1

Answer:

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

The 2 types of ions are anions and cations. Anions are negatively charged ions. Cations are positively charged ions.

H2S molecular weight= 34

% mass of elements= (atomicity x atomic weight) / (total molecular weight)  x 100

Mass % of hydrogen= (2x1)/34  x100

                                 = 5.88%

Mass % of sulphur= (32x1)/34  x100

                             = 94.12%

Ratio of H and S:

H:S = 5.88: 92.12
