Answer 1

Hi i can answer reactions part only, i don't have data to fill mass of test tube section. Please fill yourself.

Reaction 6:

NaHCO₃ (aq): Sodium bicarbonate

HCl (aq): Hydrogen chloride (Commonly called as Hydrochloric acid)

Balance equation: HCl (aq) + NaHCO₃ (aq) → CO₂ (g) + H₂O (l) + NaCl (aq)

Observations: Colorless gas bubbles out like fizz.

Type of reaction: decomposition

Reaction 7:

Pb(NO₃)₂ (aq): Lead(II) nitrate

KI (aq): Potassium iodide

Balance equation: Pb(NO₃)₂ (aq) + 2 KI (aq) → PbI₂ (s) + 2 KNO₃ (aq)

Observations: Yellow Color precipitate formed.

Type of reaction: double replacement
