Please calculate the amount of energy it will take to change 20.0 grams of Water from -3oC all the way to vapor (100oC) at sea level. Show all your work for credit.
1. heat of fusion of water = 334 J/g
2. heat of vaporization of water = 2257 J/g
3. specific heat of ice = 2.09 J/g·°C
4. specific heat of water = 4.18 J/g·°C

In chemistry, the type of an atom (what element it is) is determined by: a) the number of protons it contains in its nucleus.b) the number of neutrons it contains in its nucleus.c) the number of protons it has in a cloud around the nucleus.d) the number of neutrons it has in a cloud around the nucleus.e) the number of electrons it exchanges with its neighbors.
