Asample of lake water at 25°c is analyzed and the following parameters are found: total alkalinity = 6.2 x 10-4 m phenolphthalein alkalinity = 1.0 x 10pm ph = 7.6 hardness = 30.0 mg/l [mg²+] = 1.0 x 10-4 m extract all possible single-ion concentrations that you can by combining one or more of these data. also determine whether or not the water is at equi- librium with respect to the carbonate-bicarbonate system and whether or not it is saturated with calcium carbonate.

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.

The goal of this experiment was to answer the question "what is the effect of a gas' temperature on its volume? " you formulated the hypothesis below. hypothesis: if a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. to test this hypothesis, you changed the of the gas between 0 and 100°c (273 and 373 k) and calculated the resulting of the gas.
