If you want to melt ice into liquid water, does the ice absorbs heat or release heat? Is this endothermic or exothermic?
2 answers:
Answer:
absorbs heat, which makes it endothermic.
Explanation:
Basically melting ice is it in windows or Mac reaction makes the ice absorbs heat energy which causes a change to occur
Answer:
Endothermic
Explanation:
This would be an endothermic reaction, due to the fact that the water would be signifigantly warmer then the ice cube, which causes it to melt.

B
Explanation:

C + H2O -> H2 + CO
n(C) = 15.9/12 = 1.325 (mol)
=> n(H2) = 1.325 mol
We have:
PV = nRT
=> V = (nRT)/P
(R = 22.4/273 = 0.082)
V = (1.325 x 0.082 x 360)/1 = 39.114 (L)
