Step-by-step explanation:
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
C , the little 5 at the top represents how many times 7 is multiplied.
Example A: a/2
A fraction shows division as well! I’m not sure about the rest though....
E = 2.718281828...
rounded to 3 decimal places
2.718
