Explanation:

Chemical equation:

Fe₂CO₃ + 3C  →   2Fe + 3CO

The given reaction is single replacement reaction. In this reaction carbon react with Fe₂CO₃ and replace the iron from CO₃²⁻ and form free iron and carbon monoxide.

Chemical equation:

C₂H₄ + 3O₂   →  2CO₂ + 2H₂O

The given reaction is combustion reaction. In which ethene burn in the presence of oxygen form carbon dioxide and water.

Chemical equation:

Fe₂O₃ + 6HCl   →  2FeCl₃ + 3H₂O

The given reaction is double replacement reaction. In which anion and cation of both reactants exchange with each others.

Chemical equation:

2Al + 2Br₂ →  2AlBr₃

The given reaction is combination reaction in which aluminium and bromine combine to form aluminium bromide.

Chemical equation:

C₆H₁₂O₆   →    6C + 6H₂O

The given reaction is decomposition reaction in which glucose molecule decompose to give water and carbon.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
