Question

drop each substance in the correct category
substance dissolved in water substance in a liquid form (pure) solid substance substance in a gaseous form
br₂(l) c₆h₁₂o₆(aq) c₆h₁₂o₆(s) h₂o(l) co₂(g) zn(s)
nh₃(g) nahco₃(s) cl₂(g) co₂(aq) al(s) nahco₃(aq)

Explanation:

Step1: Identify dissolved in water

Substances with (aq) notation are dissolved in water. So $C_{6}H_{12}O_{6}(aq)$, $CO_{2}(aq)$, $NaHCO_{3}(aq)$ go in "Substance dissolved in water".

Step2: Identify liquid - pure

Substances with (l) notation and not in water are pure liquids. So $Br_{2}(l)$, $H_{2}O(l)$ go in "Substance in a liquid form (pure)".

Step3: Identify solid substances

Substances with (s) notation are solids. So $C_{6}H_{12}O_{6}(s)$, $Zn(s)$, $NaHCO_{3}(s)$, $Al(s)$ go in "Solid substance".

Step4: Identify gaseous substances

Substances with (g) notation are gases. So $CO_{2}(g)$, $NH_{3}(g)$, $Cl_{2}(g)$ go in "Substance in a gaseous form".

Answer:

Substance dissolved in water: $C_{6}H_{12}O_{6}(aq)$, $CO_{2}(aq)$, $NaHCO_{3}(aq)$
Substance in a liquid form (pure): $Br_{2}(l)$, $H_{2}O(l)$
Solid substance: $C_{6}H_{12}O_{6}(s)$, $Zn(s)$, $NaHCO_{3}(s)$, $Al(s)$
Substance in a gaseous form: $CO_{2}(g)$, $NH_{3}(g)$, $Cl_{2}(g)$
