D) the author uses imagery in the poem to explain the theme of “all good things must come to an end.”

i will mark you as brainlinest for correct !

A chemical change is when a new product is made. When the shell of an egg breaks, it doesn't form a new substance. This is the same for the flour and sugar sifting together, it becomes a mixture.

Intuition might say that chocolate squares melting might be a chemical change, but this is also not true. This is because this is just a change in state.

So, your answer is: A mixture of flour, sugar, eggs and butter is baked to become a cake
