(C) 98 g H 2 SO 4 = 1 mol H 2 SO 4 So, if there are 500 mL (which is 0.5 L), then 1 mol in 0.5 L would be equivalent to 2 mol ...

(C) A 2.0 molal solution of sucrose (C 12 H 22 O 11 ) would have the lowest boiling point because that solution would contain ...

(A) The graph of the solubility of a substance that has no change in its solubility as the temperature is increased would be a ...

(C) The graph that shows the amount of solute in solution as it is added up through its saturation point is C. The point at whi ...

(D) Graph D shows the ice getting warmer until it starts to melt. This is where the temperature stays the same until it is all ...

(C) The molar mass of Ca(OH) 2 is Ca = 40, 2 O = 32, and 2 H = 2, which added together equals 74 g/mol. If this is dissolved t ...

(B) The molar mass of C 12 H 22 O 11 is 12 C = 144, 22 H = 22, and 11 O = 176, which added together equals 342 g/mol. Because ...

8. Chemical Reactions and Thermochemistry 1. (A) A large negative heat of formation indicates that the reaction will give off a ...

(C) Because the aluminum replaces the hydrogen to form aluminum sulfate, this is classified as a single-replacement reaction. ...

(B) For a metal to replace another metallic ion in a solution, it must be higher in the activity series of elements than the me ...

(B) For a double displacement to go to completion, a product or products must either deposit as a precipitate or leave the reac ...

(D) The only salt that hydrolyzes to a strong acid and a weak base is Cu(NO 3 ) 2. This would give an acid solution. All the ot ...

(A) Salts of strong bases and weak acids react with water to give a basic solution. An example would be Na 2 CO 3 , because it ...

(A) Enthalpy is defined as the heat content of a system. ...

(B) The ΔH^0 with the superscript zero indicates that the process was carried out under standard conditions, which are 298 K an ...

(B) The property of being able to add enthalpies comes from Hess’s Law of Heat Summation and is based on the First Law of Therm ...

(D) Because the heat of the reaction is negative, it indicates that energy (heat) is given off when this reaction occurs. It is ...

(T, F) While it is true that a negative heat of formation is associated with an exothermic reaction, the First Law of Thermodyn ...

(T, T, CE) When a combination reaction results in a gas that is allowed to be released, a precipitate that drops to the bottom ...

(T, T, CE) Both statements are true and Hess’s Law is the basis for arriving at a heat of reaction by algebraically adding two ...
