Answer:
A. One unpaired electron
B. 5 unpaired electrons
Explanation:
In A ,Fe is in +3 oxidation state and Electronic configuration- [Ar]3d5
And NO2 is a strong field ligand hence it causes pairing in t2g orbitals and results one unpaired electron in dZX orbital.
In B, also Fe is in +3 oxidation state but F is weak field ligand hence causes no pairing of Electrons hence it results 5 unpaired electrons with electronic configuration t2g^3 eg^2
They multiply the number moles by Avogadro's number
Answer:
Explanation:
It's water vapor. There is enough heat present to get the water to boil but not enough to break it into its chemical components (oxygen and hydrogen), so the answer is D.
Answer:
D - water changes from a
Explanation:
You're correct!
We are asked what happens when the pressure changes from 0 atm to 10 atm at 0C.
If we look at the graph at 0C on the x axis and at 0 atm on the y axis, we can see we are in the yellow area of the graph, so the water starts at a gas.
If we keep the temperature the same, but change the pressure to 10 atm (much higher on the y axis) we are in the blue area, so the water is now a liquid. Therefore, D is correct
