The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH).
CO2 + 2LIOH → Li2CO3 + H20
The molar mass CO2 is 44.01 g/mol. How many moles of LiOH are needed to react completely with 25.5 g of CO2?
0.290
0.579
1.16
b 1.73

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.
