Answer:
B.
Explanation:
I believe it is B, it could be C too.
E. co and n2Effusion is the process where gas escapes through a hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. R<span>elative rates of effusion is related to the molecular mass.
a) M(N</span>₂)/M(O₂) = 28/32 = 0,875
b) M(N₂O)/M(NO₂) = 44/46 = 0,956
c) M(CO)/M(CO₂) = 28/44 = 0,636
d) M(NO₂)/M(N₂O₂) = 44/58= 0,758
e) M(CO)/M(N₂) = 28/28 = 1, <span>CO and N</span>₂ <span>have iexact molecular masses and will effuse at nearly identical rates.</span>
Answer:
A solution that contains a system at equilibrium is the one in which there is no change in color
Explanation:
If the color of the solution changes slowly it means that the equilibrium shifts towards the right. This happens when we add the reactant and the equilibria move towards the right that is away form the reactant increasing the product formation. But when there is no change in color it means the reaction is constant and there is a state where the concentrations of reactant and product are not changing and are constant.
Hence, the solution in which the color is not changing is at equilibrium.
