Which of the following best explains what happens when you add ice to a glass of water?(2 points) The water becomes warmer because it gains heat energy from the air.

Heat energy moves from the ice cubes to the water.

Heat energy moves from the water to the ice cubes.

The ice cubes make the water colder by releasing coolness into the water.

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
