How many moles of hydrogen are in 3.0 moles of C6H12O6?
Anastaziya [24]

Answer:

36 mol H

1 mol C₆H₁₂O₆ contains 12 mol H atoms;      Multiply by 3

3 mol C₆H₁₂O₆ contains 36 mol H atoms

If you are talking about moles of hydrogen molecules (H₂), you divide 36 by 2 and get 18 mol H₂.

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)
