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

A.

2,3 and 4

B.

2, 4 and 3

C.

1,2 and 3

D.

1, 3 and 5

Correct answer is A

xCH\(_3\)OH + yO\(_2\) → 2CO\(_2\) + zH\(_2\)O

Balancing the equation, we have

C = x (on the left) and 2 (on the right)

⇒ x = 2

2CH\(_3\)OH + yO\(_2\) → 2CO\(_2\) + zH\(_2\)O

On the left, H = 8 and on the right = 2z

⇒ 2z = 8 ; z = 4

2CH\(_3\)OH + yO\(_2\) → 2CO\(_2\) + 4H\(_2\)O

On the right, O = 4 + 4 = 8.

On the left, O = 2 + 2y

⇒ 2 + 2y = 8

2y = 6 ; y = 3

x, y, z = 2, 3, 4.
