When solutions of lead(II) nitrate and potassium carbonate are mixed, a precipitate of lead(II) carbonate forms. Pb(NO3)2 + K2CO3 --> 2KNO3 + PbCO3 (Note: Give all answer with 3 sigfigs). What is the molarity of the potassium carbonate solution if 50.2 mL are required to react with 64.4 mL of 2.56 M lead(II) nitrate?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
