Answer 1

Answer:

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
