Answer: 8855 Joules energy is released when 115 g of 
changes from a liquid to a solid at its freezing point.
Explanation:
Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.
Amount of heat released to freeze 1 gram of = 77 J/g
Mass of given = 115 gram
Heat released when 1 g of is freezed = 77 J
Thus Heat released when 115 g of is freezed =
Thus 8855 Joules energy is released when 115 g of changes from a liquid to a solid at its freezing point.
Answer:
In a closed system the vapor pressure and the measured pressure of a gas increases.
Explanation:
as the pressure of the liquid increases the measured pressures also increases with a given temperature.
"Atoms have an equal proton and neutron charge."
Answer:
Dalton's says atoms of different elements differ in size and mass, whereas the modern theory says they differ in average mass. Dalton's says atoms are individual particles, whereas the modern theory says atoms are divisible into subatomic particles like protons, neutrons, and electrons..
