Calculate the heat (in joules) absorbed by the system for each of the following examples (the system is given in italics). Specify the sign of the heat. a. 100g of liquid water is heated from 0°C to 1000°C at 1 bar
b. 100g of liquid water is frozen to ice at 0°C at 0.01 bar
c. 100g of liquid water is evaporated to steam at 1000°C at 1 bar

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
