I am pretty sure that the answer is true
<span>A) This solution was not basic when it was heated in part 3. ( in part 3 i convertedCu(OH)2 to CuO).
Incorrectly low, because not all copper compounds will precipitate out
B) A slightly blue solution was decanted from Cu in part V. (in part 5 i reduced Cu(H20)6 ions with zink)
Incorrectly low, because some copper were thrown away
C) In part 5 the water in the beaker boiled away, exposing the evaporating dish to excess heat (same as above).
incorrectly high, because other compounds might be present as well </span>
Answer: Option (e) is the correct answer.
Explanation:
An equilibrium reaction is defined as the reaction where rate of forward reaction will be equal to the rate of backward reaction.
For example, 
So, here amount of reactants that is, nitrogen gas and hydrogen gas will be constant along with constant amount of formation of product that is, ammonia here.
In an equilibrium reaction there is presence of both reactants and products and hence, both reactants and products constitute the system.
Thus, we can conclude that all the given statements are true.
