Assuming constant conditions, how many milliliters of chlorine has react to yield 1.55 L of dichlorine trioxide

Which best describes why nh4+ can form an ionic bond with cl-?

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

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