A solution is created by dissolving 0.0362 g of Mg(OH)2 in 400.0 mL solution. Determine the pH of this solution.

Use the information below to predict the characteristics of an equilibrium reaction 2A (aq) + 2Z (aq) ⇌ 2AZ (aq)        ΔG0 = -11.5 kJ/mol The value of the equilibrium constant for the reaction will be 1. 1.04 x 102 2. 9.64 x 10-3 3. 4.38 x 104 Which indicates that 4. The reaction is spontaneous in the forward direction 5. The reaction is spontaneous in the reverse direction And therefore 6. The concentration of reactants will be higher than concentration of products at equilibrium 7. The concentration of products will be higher than the concentration of reactants at equilibrium

Predict what happens when 0.400 g of K2SO4 is added to 0.500 L of a 0.500 M AgNO3 The Ksp of Ag2SO4 is 1.2 x 10-5.

A 0.075 M solution of an unknown weak acid has a pH of 2.38. Determine the percent ionization of that acid.

Determine if the following statements are correct regarding the graph of rate data above? The half-life, t1/2, is independent of the initial concentration [1] Doubling the concentration of A would not change the rate of the reaction. [2] The rate constant, k, would have units of M-1 s-1 [3]

Consider a saturated solution of MCl3 with a molar solubility of 0.12 M. What do you expect to see when you add 0.1 M NaCl to the solution (assume that there is no change in volume) The reaction will shift left The reaction will shift right The reaction will not be affected As a result of which The molar solubility will increase The molar solubility will decrease The molar solubility will remain unchanged
