Question

D Question 4 1 pts The reaction shown is at equilibrium. If a student adds more X to the system, what happens immediately (at that instant) to Q and K? X Y Z Both decrease Both increase O Qgets larger and gets smaller K gets larger and gets smaller Kremains constant and increases Kremains constant and a decreases 1 pts Question 5 You have a saturated solution of Ca(OH)2 in a flask, meaning there is some solid CaOH)2 sitting at the bottom of the aqueous solution. Which of the following will increase the Ca? concentration in solution? Adding water to the solution Adding HCl(aq) to the solution Adding KOH(aq) to the solution Adding more CaOH)>(s) to the flask.

Answer 1

к until temperature is changed. does not change and remain constest Now, a Q = [2] [x][y] of more x is added, the a will decrease. so, The correct option is K remains constant and a decreases. (6) Adding water to the solution make more solute dissolve since solubility of a salt depends on the amount of salt dissolved per unit of volume. Herne, Ca2+ coren will nisare Adding HCl to the solution will make Calon), to dissolve. This is because the Ht from Hill will combine with On con from Calohl, and will make the reaction to move forward. Herne, more Cazt conen in solution
