Decision-tree practice
Answer Q1: Uniform composition? Then Q2: Chemically breakable (compound) or settle out (suspension)? Click each card to check.
Mystery A
Distilled water
Uniform? Yes — chemically breakable?
CLASSIFICATION
Pure substance — COMPOUND (H2O; can be broken into elements chemically)
Mystery B
Air (fresh sample)
CLASSIFICATION
HOMOGENEOUS MIXTURE of gases (N2, O2, Ar, CO2 …) — uniform gases, not chemically recombined
Mystery C
Muddy pond water
CLASSIFICATION
SUSPENSION — heterogeneous; particles settle out
Mystery D
Gelatin dessert
CLASSIFICATION
COLLOID — uniform; scatters light; never settles
