Question

do some research. find out as much as you can about the three gases that students thought might be released during part 3. record your notes in the space provided below.
nitrogen
chlorine
carbon dioxide
colorless
odorless
flame goes out
does not turn cloudy

Explanation:

• Nitrogen:
• Physical properties: Colorless, odorless gas.
• Chemical properties: Generally inert, does not support combustion (flame goes out), does not react with limewater (does not turn cloudy).
• Chlorine:
• Physical properties: Green - yellow gas with a pungent odor.
• Chemical properties: Supports combustion in some cases (e.g., with some metals like sodium), has strong oxidizing properties.
• Carbon dioxide:
• Physical properties: Colorless, odorless (at low concentrations) gas.
• Chemical properties: Does not support combustion (flame goes out), reacts with limewater (\(Ca(OH)_2\)) to form calcium carbonate (\(CaCO_3\)) which makes the limewater turn cloudy (\(CO_2 + Ca(OH)_2=CaCO_3\downarrow + H_2O\)).

Answer:

Nitrogen	Chlorine	Carbon dioxide
