Below are sample questions representative of the exercises included on this worksheet and related 7.76 Elements, Compounds, and Mixtures skill assessments:

Problem 1Difficulty: Mastery
A table in the image lists four samples and a student's completed chart. Which row in the chart is entirely correct?
ARow A
BRow B
CRow D
DRow C
Solution & Explanation:Row B is fully correct because a pure 1:1 sodium-chlorine pattern represents the compound NaCl. The other rows use incorrect classifications.
Problem 2Difficulty: Mastery
Use the image of the unknown sample. The pattern shows only one repeating particle type made from sodium and chlorine in a 1:1 ratio. Which option is correct?
Aelement; Na
Bcompound; Na2Cl
Cmixture; Na and Cl
Dcompound; NaCl
Solution & Explanation:A pure sample with one repeating sodium-to-chlorine ratio of 1:1 is the compound NaCl.
Problem 3Difficulty: Mastery
Air and bronze are very different materials, but which statement correctly explains why both are classified the same way?
ABoth are elements because each contains a common main ingredient.
BBoth are mixtures because their components are physically combined and not in one fixed formula.
CBoth are compounds because they contain more than one kind of atom.
DBoth are compounds because they can look uniform.
Solution & Explanation:Mixtures can be gases, liquids, or solids. Air and bronze are both combinations of substances without one fixed chemical formula.
