Question 1 Report

Consider the reaction represented by the following equation: xCH\(_3\)OH + yO\(_2\) → 2CO\(_2\) + zH\(_2\)O. The values of x,y and z respectively, are

Answer Details
The chemical equation represents the combustion of methanol (CH\(_3\)OH) in the presence of oxygen (O\(_2\)). The reactants, methanol and oxygen, combine to produce carbon dioxide (CO\(_2\)) and water (H\(_2\)O). The balanced chemical equation for this reaction is: 2CH\(_3\)OH + 3O\(_2\) → 2CO\(_2\) + 4H\(_2\)O From this equation, we can see that the values of x, y, and z respectively are 2, 3, and 4. Therefore, the correct option is (A) 2, 3, and 4.
