Question

A(n ______ is a well-blended mixture that appears to be a single substance

a) compound b) element

c) pure substance d) solution

Answer 1

None of the choices is a suitable fill-in for the blank.

The question is fishing for "solution", but that makes
the statement false and misleading.

Salad dressing is a well-blended mixture. 
Blood is a well-blended mixture. 
Milk is a well-blended mixture. 
Petroleum is a well-blended mixture. 
None of these substances is a solution. 
A solution is not a well-blended mixture.
