Front 1

what is oxidation?

Back 1

the loss of electrons or an increase in oxidation state by a molecule, ion or atom

Front 2

what is reduction?

Back 2

the gain of electrons or a decrease in oxidation state by a molecule, ion or atom

Front 3

A(n) _____ is a compound with hydrogen ion activity less than water, while a(n) ______ is a compound with a hydrogen activity greater than water

Back 3

base
acid

Front 4

oxidation/reduction actions reactions involve the acceptance and donation of _________.

Back 4

electrons

Front 5

what is a catalyst?

Back 5

a chemical reaction in a series of steps, with various intermediate products, which ultimately form the final products of the reaction

Front 6

A catalyst provides an ____________ for a reaction to occur. Typically, the catalyst will be involved in on of the "steps" that occur in the reaction, but is reformed before the completion of the reaction, so that the catalyst is not used up.

Back 6

alternate pathway

Front 7

The alternate pathway generally allows the reaction to proceed faster, as well as lower the _______ _______.

Back 7

activation energy

Front 8

true or false
Reactions need a certain amount of energy to happen.

Back 8

true

Front 9

A ________ lowers the amount of energy needed so that a reaction can happen more easily.

Back 9

catalyst

Front 10

what is activation energy?

Back 10

the energy needed to make a reaction happen

Front 11

the energy a reaction needs is usually in the form of ______.

Back 11

heat

Front 12

what are inhibitors?

Back 12

slow the rate of reaction

Front 13

what is an enzyme?

Back 13

molecules of protein that are made from amino acid chains. they are produced by all living organisms and plants. the structure establishes the functions or uses of enzymes.
