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
Answer:
40
Step-by-step explanation:
The volume of a prism is the base area * height. We know the base area is 15 and the volume is 600, so the height must be 600/15 = 40.
Its a repeating decimal 0.22222222222222222222222
