QuestionA sample of dissolved in ethanol is best described as what type of mixture? (A) element (B) compound (C) allotrope (D) heterogeneous mixture (E) homogeneous mixture
Studdy Solution
STEP 1
Assumptions1. The sample of NaCl(s) completely dissolves in ethanol. . The resulting sample is transparent and uniform.
STEP 2
We need to understand the definitions of the given options to identify the best description of the sample.
(A) Element A substance that cannot be broken down into simpler substances by chemical means.
(B) Compound A substance formed when two or more chemical elements are chemically bonded together.
(C) Allotrope Different forms of the same element in the same physical state.
(D) Heterogeneous mixture A mixture that is not uniform in composition - its components are not evenly distributed throughout the mixture.
(E) Homogeneous mixture A mixture which has uniform composition and properties throughout.
STEP 3
We can rule out options (A), (B), and (C) because NaCl dissolved in ethanol is not an element, a compound, or an allotrope. NaCl is a compound, but when it's dissolved in ethanol, it forms a mixture, not a compound or an allotrope.
STEP 4
Now we need to determine whether the mixture is heterogeneous or homogeneous. The problem states that the sample is transparent and uniform, which means the components are evenly distributed throughout the mixture.
STEP 5
Based on the definitions and the given information, the best description of the sample is a homogeneous mixture. So, the answer is () homogeneous mixture.
