Step 1:
I'll help you complete this gas properties chart systematically.

I'll provide details for each gas based on standard chemical properties.

Step 2:
: Carbon Dioxide (\mathrm{CO}_{2})

- Behavior with water: Slightly soluble, forms carbonic acid $$\mathrm{CO}_{2} + \mathrm{H}_{2}\mathrm{O} \rightarrow \mathrm{H}_{2}\mathrm{CO}_{3}
- Appearance: Colorless gas - Reaction with flame: No combustion (flame extinguisher)

Step 3:
: Hydrogen (\mathrm{H}_{2})

- Reaction with flame: Highly flammable, produces "pop" sound $$2\mathrm{H}_{2} + \mathrm{O}_{2} \rightarrow 2\mathrm{H}_{2}\mathrm{O}
- Appearance: Colorless, invisible gas - Limewater test: No reaction - Behavior with water: Insoluble

Step 4:
: Acetylene (\mathrm{C}_{2}\mathrm{H}_{2})

- Appearance: Colorless gas with garlic-like odor - Reaction with flame: Highly flammable, luminous flame - Limewater test: No reaction - Behavior with water: Slightly soluble

Step 5:
: Hydrogen Chloride (\mathrm{HCl})

- Behavior with water: Highly soluble, forms hydrochloric acid $$\mathrm{HCl} + \mathrm{H}_{2}\mathrm{O} \rightarrow \mathrm{H}_{3}\mathrm{O}^{+} + \mathrm{Cl}^{-}
- Appearance: Colorless gas - Reaction with flame: No combustion - Limewater test: No reaction

Step 6:
: Ammonia (\mathrm{NH}_{3})

- Behavior with water: Highly soluble $$\mathrm{NH}_{3} + \mathrm{H}_{2}\mathrm{O} \rightarrow \mathrm{NH}_{4}^{+} + \mathrm{OH}^{-}
- Appearance: Colorless gas with pungent odor - Reaction with flame: Burns with pale yellow flame - Limewater test: No reaction

Final Answer

The completed chart provides chemical properties and reactions for each gas, highlighting their unique characteristics in different environments.
