Chemistry hw due in 2 hours... HELP!!!

Answer 1

36kcal

Step-by-step explanation:

There are three things that occur in the process not converting ice to steam. They are;

I) fusion of ice

ii) heating of water to 100°C

iii) vaporization of water at 100°C to yield steam

Hence, total heat required to convert ice to steam=

Latent heat of fusion of ice + heat required to raise the temperature of water to 100°C + Latent heat of vaporization of water

Thus;

H= mLfus + mcθ + mLvap

H= m(Lfus + cθ + Lvap)

H= 50(80 + 1(100) + 540)

H= 36000cal

H= 36kcal
