) According to the reaction : Na2SO4(aq) + BaCl2(aq)
2NaCl(aq) + BaSO4
What is the molarity of Na2SO4 solution when 250 mL of it are required to
precipitate 5.28 g of barium sulphate ?
Please answer

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
