The half-life of a certain level of reaction is 2.5h. Then the rate constant of the reaction k=? If the concentration of the reactants in this reaction is reduced to 25% of the initial concentration, how much time is required?

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).
