Determine the molar solubility of pbso4 in pure water. ksp (pbso4) = 1.82 x 10-8. a. 1.82 x 10-8 m b. 1.35 x 10-4 m

Arock can be broken down into different kinds of substances by physical processes. no chemical reactions are needed to separate different parts of a rock into pure substances. this is because a rock is a(n)

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.
