What is an adsorbent used for?
a. an adsorbent is used to separate mixtures by the adhering of one chemical component to a solid surface because of its chemical properties.
c. an adsorbent is used to separate mixtures by size.
b. an adsorbent is used to separate mixtures by boiling point.
d. an adsorbent is used to separate mixtures by their solubility.

Explain the relationship between forward and backward reactions in equilibrium, and predict how changing the amount of a reactant (creating a tension) will affect that relationship.

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.
