Hello,
I'm not very sure but I think the correct answer is D) Water Wave
I really hope this helps!!!! Happy Holidays!!!! (:
Answer:
The solutions should be added in this order NaCl > Na2SO4 > Na2S
Explanation:
Silver is insoluble as a chloride, so the silver ions get precipitated on addition of chloride ion as silver chloride. This means Ag+ would be removed the first.
So we will add NaCl in the first step.
The following reaction will occur.
Ag+ + Cl- → AgCl(s)
Both, Pb2 and Ni are soluble as chlorides. (lead chloride is soluble as a hot solution but will ppt when colder).
When we add Na2SO4, Pb2+ will get precipitated (because it's insoluble) as PbSO4 and Ni will remain soluble as NiSO4 is soluble in water.
The reaction that will occur is:
Pb^2+ + SO4^2- → PbSO4(s)
Nickel is insoluble as a sulfide. So when we will add Na2S, nickel will be precipitated as sulfide and be able to separate and be collected.
The solutions should be added in this order NaCl > Na2SO4 > Na2S
Answer:
The equilibrium will go right, increasing the quantities of Y(g) and Z(s), when the amount of X(g) increases.
Explanation:
Equilibrium is a state in which the velocity of the formation of the products is equal to the velocity of the formation of the reactants. Thus, the concentrations remain constant.
By Le Chatêlier's principle, when the equilibrium is disturbed, the equilibrium must shift to reestablish the equilibrium. Thus, when X is put in the container, it intends to decompose and form Y and Z, thus, as higher is the initial X, as higher is the Y and Z formed.
