Question

For each reaction, determine whether it is an example of combustion or not. 2 C 2 H 6 + 7 O 2 ⟶ 4 C O 2 + 6 H 2 O Choose... 2 N 2 O 5 ⟶ 4 N O 2 + O 2 Choose... C O 2 + 4 H 2 ⟶ C H 4 + 2 H 2 O Choose... C + O 2 ⟶ C O 2 Choose... 2 N O + O 2 ⟶ 2 N O 2 Choose...

Answer 1

Answer:

3,4and 5are an example of combination but 1 and 2 are not example of combination.

I hope it is helpful for you...

Answer 2

The reactions 2N₂O₅ → 4NO₂ + O₂ and CO₂ + 4H₂ → CH₄ + 2H are not combustion reactions.

• A combustion reaction is defined as a process that reacts with oxygen and produces flame and heat energy as a product.

• So to determine wheater a reaction is a combustion reaction or not we need to find the presence of oxygen in the reactant.

• In the first reaction, C₂H₆ reacts with O₂ therefore it is a combustion reaction.
• In the second reaction, N₂O₅ does not react with oxygen similarly in the third reaction CO₂ not does react with oxygen, therefore, they both are not combustion reactions.
• The other two reaction C and NO reacts with O₂ therefore the reactions are combustion reaction.
