Yes you are correct good job!
Explanation:
1=2 atoms
2=4-n where n is the number of bonds to that carbon
3=10
4=2
Answer:
"Ar 3d3 4s2" is the electronic configuration for Vanadium.
The balanced chemical equation is:
2Fe+3H2O=Fe2O3+3H2
We are given the amount of water to be used in the reaction. This will be the starting point for the calculations.
3 mol H2O ( 1 mol Fe2O3 / 3 mol H2O ) = 1 mol Fe2O3
Therefore, the correct answer is option B.
