100.000g of water at 80.0oc was mixed with an equal amount of cool water in a calorimeter. the final temperature of the water in the calorimeter is 50.0oc. what is the heat (q) in kilojoules for the hot water? (specific heat for water is 4.18j/goc).

Which of the following statements are incorrect?

1) a. water molecule breaks up into hydrogen and oxygen on passing electricity. does this involve breaking intermolecular or intramolecular forces of attraction. explain b. on boiling water changes to water vapor. does this involve breaking intermolecular or intramolecular forces of attraction. explain methanol evaporates faster than water. contrast the intermolecular forces and the vapor pressures of methanol and water?

When a chemist collects hydrogen gas over water, she ends up with a mixture of hydrogen and water vapor in her collecting bottle if the pressure in the collecting bottle is 97.1 kilopascals and the vapor pressure of the water is 3 2 kilopascals, what is the partial pressure of the hydrogen?
