Question 20 (1 point) In a lab experiment, 24.0 grams of carbon (C) react with 64.0 grams
of oxygen to form carbon dioxide (CO2) according to the following
equation:
C + 0₂ - CO2
9
The mass of CO2 formed by the reaction is
12
40.0 g
88.08
15
00.3758
2.67 g

Iwill give extra points to who gets this right

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.

Nonpoint source pollution is difficult to control because it
