Question

Identify the type of reaction which will occur based on the formation provided about the reactants:
$\mathrm{C}{\mathrm{H}}_4\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to$
Synthesis
A. Decomposition
B. Single Replacement
C. Double Replacement
D. Combustion

Answer 1

Hint: We know that the reaction in which reactant reacts with atmospheric oxygen usually gives the two products, they are carbon dioxide and water. The heating process of any compound will take place with the atmospheric oxygen.

Complete step by step answer:
As we already know, the word combustion is usually used for heating. The one primary reactant of the combustion reaction is oxygen, which is obtained from the atmospheric air and produces the two main products; one of them is carbon dioxide, and the other one is water vapor. The complete reaction is shown below.
$\mathrm{C}{\mathrm{H}}_4\left(\mathrm{g}\right)+2{\mathrm{O}}_2\left(\mathrm{g}\right)\to \mathrm{C}{\mathrm{O}}_2\left(\mathrm{g}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$
In the above chemical reaction, one mole of gaseous methane reacts with two moles of atmospheric oxygen generally gives the products one mole of carbon dioxide and two moles of water vapor. The heating process generally depicts the combustion reaction, and it transfers the energy from the surroundings.

Therefore, the correct choice for this given question is E.

Note:
The combustion reaction is the sort of reaction in which oxygen is one of the main reactants and produces a product carbon dioxide and water vapor.
$\mathrm{C}{\mathrm{H}}_4\left(\mathrm{g}\right)+2{\mathrm{O}}_2\left(\mathrm{g}\right)\to \mathrm{C}{\mathrm{O}}_2\left(\mathrm{g}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$
