How to work out the rate of reaction in chemistry

One way you can work out the rate of reaction is by the amount of product that is produced to time. This can also be done with heat and time.

Hope this helps! :)

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).
