Consider the reaction represented by the following equation: xCH3OH + yO2 → 2CO2 + zH2O. The values of x,y and z respectively, are
2,3 and 4
2, 4 and 3
1,2 and 3
1, 3 and 5
Correct answer is A
xCH3OH + yO2 → 2CO2 + zH2O
Balancing the equation, we have
C = x (on the left) and 2 (on the right)
⇒ x = 2
2CH3OH + yO2 → 2CO2 + zH2O
On the left, H = 8 and on the right = 2z
⇒ 2z = 8 ; z = 4
2CH3OH + yO2 → 2CO2 + 4H2O
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.
