Answered by Steve
sorry. Neither one, if by "pure substance" you mean an element.

Nickel and saltwater.

Rust is made up of iron, copper, and trace amounts of gold. So it would be B and C.
Answered by Damon
Nickel is an element

Fruit juice = mixture
salt water = solution of NaCl and others in water
rust is a compound (oxide of iron) of iron and oxygen as they showed you Fe2O3 !

Maybe I'm out of touch and need to go back to school.When I read this I consider rust (if Fe2O3) as a pure substance. Actually it isn't Fe2O3 either but a mixture of Fe2O3 and FeO. When I read nickel I read 5 cent piece and that isn't pure. I would chalk this up to a poorly worded question.
