Consider the dissociation of strong versus weak acids: HCl(aq) H2O(l)H3O (aq) Cl(aq)HF(aq) H2O(l)H3O (aq) F(aq) The first reaction is not reversible, but the second one is. So, only the conjugate of the weak acid, F, can react with H3O . Now consider the solubility of insoluble salts: AgCl(s)Ag (aq) Cl(aq)AgF(s)Ag (aq) F(aq) The addition of acid has no effect on silver chloride. But for the second reaction, H3O will react with F, decreasing its concentration and driving the equilibrium to the right. Thus, salts that contain the conjugate of a weak acid become more soluble as the acidity of the solution increases. Another metal phosphate is cobalt(III) phosphate. It will behave similar to calcium phosphate in an acid solution, and will form an equilibrium between reactants and products. What is the net ionic equation including phases for CoPO4(s) dissolving in H3O (aq) ? Express your answer as a net ionic equation.

An artist makes dice by carving them out of rock. Due to random events, not all cubes have the same size. The size is measured by the dimension, X, which can be either length, width or height as we assume they are all equal. The dimension is normally distributed with $\mu$ = 2.00 cm and $\sigma$ = 0.10 cm. a) Determine the probability that a die will have dimensions above 2.30 cm The artist decides that the 90% of the dice that are closest to 2.00 cm in dimension, will be sold. The ones that are either too small or too large are discarded. b) Determine the range of dimension of dice that are sold The artist paints the six surfaces of the dice. In order to evaluate how much paint is required for each die, he investigates the total surface area of a die. The total surface area can be calculated from the formula A = 6 \cdot X$^2$. c) Determine the mean and standard deviation for the total surface area of the dice. The probability of rolling either of the 6 outcomes (1-6) is equal and each roll is independent of the others. The artist rolls six dice. d) Calculate the probability that the artist rolls one of each outcome with the six dice
