Select all that apply:   It has a very high boiling point when compared to other compounds of similar molecular weight.     It is less dense than water in the solid state.     It has a low level of cohesion.     It can dissolve polar substances, ionic substances, and even some nonpolar gases.

When 30.87 grams of fictional compound X is added to water to make 438.9 grams of solution, the temperature increases from 26.23 °C to 62.34 °C. What is the heat of solution for compound X given that the molar mass of compound X is 130.58 g/mol? Assume the specific heat capacity of the solution is 4.18 J/g°C.     -280.2 kJ/mol     280.2 kJ/mol     -66.24 kJ/mol     4.649 kJ/mol     66.24 kJ/mol

If you drop a 150 gram piece of metal that has a temperature of 125 Celsius into 1000 grams of water at 20 Celsius, what best describes what would occur? More heat will be lost by the metal than gained by the water. The temperature of the water will be greater than the amount of heat lost by the metal. The temperature change of the metal will equal the temperature change of the water. The heat lost by the metal will equal the heat gained by the water.

Calculate the amount of heat needed to raise the temperature of 55.0 g of liquid water from 25°C to 99°C. The specific heat of liquid water is 1.00 cal/g °C

Specific heat is defined as ___- The amount of energy needed to raise the temperature of 1 g of a substance by 1° K - The amount of energy needed to raise the temperature of 1 g by substance of 1° C - The amount of energy needed to raise the temperature of water by 1° C - The amount of energy needed to raise the temperature of a substance by 1° C
