Answer:
1) single replacement
2) combustion reaction.
3) double replacement reaction
4) combination reaction
5) decomposition reaction
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.
Solid liquid gas or plasma. Solid would be ice cubes (frozen state), liquid would be the water inside of the glass, the gas would be when you take that same water and place it on a stovetop to bring to a boiling point. (Gas state) and finally the plasma state is when you your gas particles (from the gas state) if you heat the gas particles, they will turn to plasma.
