Substance X has a melting point of -20 C and a boiling point of 60 C. Solve the questions based on the previous and the following information:
cSolid: 0.600 J/g(C)
cLiquid: 1.50 J/g(C)
cGas: 0.300 J/g(C)
Hfusion: 234 J/g
Hevaporation: 1230 J/g
Molar mass: 185 g/mol
a) What is the change in energy for 10.0g X to go from liquid -20 C to solid -20 C
b) what is the change in energy for 10.0 g X to go from 0.00 C to 20.0 C
c) X is heated up from -30 C to 40 Cusing 1800.0 J of energy. How many moles of X is heated up d) Ice at 0.00 C is put into 20.0 g of X at -15 C, causing subtance X to heat up to -5 C. If ice has a specific heat of 2.09 J/g(C), what mass of ice was used
e) you add 10 g X at -125 C with 40 g X at 0 C, what is the final temperature and what % is in which state of matter?
f) You add 6540 J of energy to 5 g X at 50 C, what is the final temperature and what % is in which state of matter?
