Chemical changes in my recipe

When you cream the butter and sugar and beat in the eggs and vanilla.When you combine flour, Baking powder, and salt and blend it into the first mixture.When you blend together the cocoa powder and butter.Those three are chemical changes because they are mixed into different substances.The last chemical change is when you bake it because the mixture hardens and forms the brownies, therefore changing the form.

Physical changes in my recipe

When you cut the brownies into squares it is still the same substance.When you divide the batter in half it is still the same.

Is it practical to make adjusted amount?

It is very important that I adjust the formula so that way I know how much ingredients I need in order to make enough for the whole entire class. If I do not adjust it then I would have to make two batches and have a lot left over.
