No chemical change occurs, they are still salt and water.

Answer:

Some elements are gold and oxygen and some compounds are sugar and salt. These are some elements and compounds mention in the poem 'Mr. Purey's Lab'.

Explanation:

There are three forms in which matter is found. These are elements, mixtures and compounds. Elements are those which are made up of atoms. Mixtures are those which is made up by combining more than one substance and there is no chemical change. Compounds are those which form from two or more elements and their chemical properties change.

Here in this question we have to identify the elements and compounds mentioned in the poem so elements are gold and oxygen and compounds are sugar and salt.
