Choose the pure substance from the list below.
a.tea
b.a casserole

d.sugar water
e.pomegranate juice

Answer 1

A, B, D, and E are all wrong. C is the right answer. C is a compound.
A, B, D and E are not unique. A pure substance is something with unique characteristics and if it can be broken down, the result is two or more pure substances. AKA only compounds and elements. This is an easy question so try to study.
