ions are atoms or groups of atoms with positive or negative
charges. the charges of some ions are given in the table.
use these values to find the total charge of 8 phosphate,
7 chloride and 2 aluminum atoms.

Total charge= -25

Step-by-step explanation:

Given :

Charges of some ions

Aluminium    +3

Phosphate     -3

Chloride         -1

Silver               +1

To find total charge on 8 phosphate,7 chloride and 2 Aluminium atoms

Aluminium    +3 × 2 =+6

Phosphate     -3 × 8 = -24

Chloride         -1 × 7 = -7

total charge=

+6-24-7 =+6 -31

= -25

a = 11 : 4

b = 38

c = 1 for every 6

i believe the answer is d.

hope it you! : d
