Answer: 8.0 moles
Explanation:
0.6661 moles×12 H≈8.0 moles
Solid liquid and gas
when it changes from a:
solid
to a
liquid: melting, fusion
gas: sublimation
liquid
to a
solid:freezing
gas:vaporization
gas
to a
solid:condensation, deposition
liquid: condensation, liquefacation
A) 10.0g of Iron is
of Iron.
One mole of dihydrogen is required to form one mole of iron, hence you'll need
of dihydrogen.
B) Likewise : 2.50g of Iron is
of Iron, hence we'll need
of Fe2O3.
I heard of this before I think I know the answers.
1st one, I'm thinking D. Because Turning Liquid into a Solid means like it would take energy out since its freezing.
2nd one, I would choose A
B and C why would they slow down if they were still in a solid. they attracted one another, but they stood still(Didn't move). D is explaining how Liquid turns into a Solid, so this is definitely incorrect. So I would choose A.
I really do hope this helps you out. (Idk about the 1st, but 2nd I think its the answer)
93.21 miles hope this is correct and hoped I helped you
