1. 1What is the concentration of a solution that was made by adding 10.00 g of KF in 2.0 L in water?

   1. A5.0
   2. B.13
   3. C.086
2. 2What is the pH of an aqueous that has a hydroxide ion concentration of 1.00 * 10^-5

   1. A5
   2. B14
   3. C9
3. 3COBr2 (g) = CO (g) + Br2
   According to Le Chatelier's principle, what would happen if more carbon monoxide were added to the system?

   1. ABr2 would react with CO to produce COBr2 to minimize the increase in CO
   2. BBr2 would react with CO to produce COBr2 to increase the production of CO
   3. CCOBr2 would decompose to produce CO and Br2 to increase the production of CO
4. 4What products are formed when sulfuric acid, H2SO4 and magnesium hydroxide, Mg(OH)2 react in an acid base reaction?

   1. AMagnesium sulfate hydrogen
   2. BMagnesium , sulfur, and water
   3. CMagnesium, sulfate, and water
5. 5which stress will increase the production of NO(g) in this equilibrium reaction?
   4NH3+5O2+$NO+6H2O

   1. AIncrease the pressure of the reaction
   2. BConstantly remove water
   3. CRemove ammonia from the reaction mixture
6. 6What happens when a chemical reaction reaches equilibrium?

   1. AThe amount of reactants and products remain constant because the reaction stops
   2. BThe rate of the forward reaction is the same as the rate of the reverse reaction
   3. CThe reaction reverses so some of the products are converted back into reaction
7. 7What is the pH of a solution with a hydrogen ion concentration of 1.0 * 10^ -6 mol/L?

   1. A1
   2. B12
