Tutor Answer
Hi Kendra,
First we define pure substance, mixture, heterogenous, and homogenous:
A pure substance is one compound by itself
A mixture is 2 or more compounds
A heterogenous mixture has compounds unevenly distributed
A homogenous mixture is evenly distributed throughout
So:
A) A chocolate chip cookie: heterogenous mixture- the ingredients are not evenly distributed
B) water: depends distilled water is pure, whereas tap water would be a homogenous mixture
C) vodka: pure
D) a pure gold coin: pure
