Step-by-step explanation:
Answer: 12.4 cm
Step-by-step explanation:
Since we are given the volums, we can work our way backwards to solve for radius, and then for diameter.
Now that we have r, we multiply it by 2 to get diameter.
2×6.2=12.4
A isn’t correct because there is 2 O’s on the left side and 3 on the right
B is incorrect because there is an S on the right but not on the left
C is incorrect because there are 2 Ca on the left side and 1 on the right
D is balanced as there are 2Na ok each side, 2Cl on each side,2H, and 1 SO4 on each side
I am not sure, but here goes. 2 + 2 + 5 4 + 5 = 9 or double 2 is 22 + 5 = 27.
This is probably wrong.
