(a)
Answer to Problem 16A
Classified as a mixture.
Explanation of Solution
Substance is made up of the similar types of the atoms. A sample of matter with both definite & constant composition and also distinct chemical properties called a pure substance. A mixture is the combination of similar or dissimilar components. The property of mixture depends on the components present in a mixture. According to this, the Atlantic Ocean on a sunny day contains many things. So, it is a mixture.
(b)
