⦁ Given the following pH values, determine the [OH-] and [H3O+] of each solution

⦁ pH = 7.00

⦁ pH = 4.00

⦁ pH = 12.0

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Ithink its called the coefficent.

The law of conservation of mass states that a mass of an object or the amount of matter composed inside an object or thing will not change unless it is added or removed of the matter that is contained in the object itself.
