Point N is on line segment MO. Given NO = 2x – 3, MO = 3x + 5, and MN = 2x + 3, determine the numerical length of MO.

What is the percentage by mass of silicon (si) in iron aluminum silicate (fe3al2(sio4)3)?

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.
