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
What do the instructions say?
10(.5 + 6)=8
If you need me to explain, let me know.
Answer:
A) 2(9x - 2)
Step-by-step explanation:
The greatest common factor of 18x and -4 is 2.
B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.
C is wrong because 18x cannot be divided by 4 to produce a whole number.
D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.
