Abase is added to water. what happens when the position of equilibrium lies to the left?
a. the base is completely dissociating into products.
b. the base is partially dissociating into products.
c. the base is not dissociating into any ions.
d. the base is present in very small amounts.

B. The base is partially dissociating into products

Explanation:

If the reaction reaches equilibrium, it is reversible, so at the same time the reactants are producing the products, the products are producing the reactants. In equilibrium, the velocity of these reactions are the same, and the concentration remains constant.

So, let's suppose a base C(OH), in water its decomposition is:

C(OH) ⇄ C⁺ + OH⁻

If something disturbs the equilibrium, the reaction shift to the side that minimizes the disturb. So, if the position of equilibrium lies to the left, more reactant is formed, so fewer ions are formed, then the base is only partially dissociating into products.

3 hours because it is a decent distance.

they are called fossil fuels
