Answer:d
Step-by-step explanation:
Answer:
There was 62.23% change in radius as the ion formed.
Step-by-step explanation:
Given
Radius of Aluminium
atom = 143 pm
Radius of Aluminium
atom = 54 pm
Change is the radius = Radius of Aluminium
atom - Radius of Aluminium
atom = 143 -54 = 89
Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium
atom and multiply by 100 we get
% Change is the radius = 
Hence there was 62.23% change in radius as the ion formed.
Answer:
37.68
Step-by-step explanation:
The formula to be used is 1\3πr^2h
so going by the question π=3.14,r=2,h= 9
when u substitute each value into the formula u get you answer to be 37.68
-8m-2(-6+2m) = -84
-8m+12-4m = -84
-8m-4m = -84-12
-12m = -96
12m = 96
m = 96/12 = 8
