2.200 mL of a solution containing 0.4 M Copper (II) Sulphate (CuSO4) is mixed with a 300 mL solution of 0.5 M Sodium Hydroxide (NaOH). The precipitate is then collected. Determine the theoretical mass of the precipitate.

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).

The se-ci  bonds is more polar  than s-br bond

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
