Explain the relationship between forward and reverse reactions at equilibrium and predict how changing the amount of a reactant or product (creating a stress) will affect that relationship. For example (select one from each underlined section)
If the amount of (reactant or product) increases, the rate of the (forward or reverse) reaction will (increase or decrease) to reach a new equilibrium.

If the amount of (reactant or product) decreases, the rate of the (forward or reverse) reaction will (increase or decrease) to reach a new equilibrium.

a c d and f

just finished the assignment

the right answer is c i just did the question.

b.false that your answer

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
