Question

In the following combustion reaction, what is the mole ratio of diatomic oxygen to water?2 C2H6 + 7 O2(g) --> 4 CO2 + 6 H2O

A. 6/7
B. 7/4
C. 7/6
D. 6/7

Answer 1

Answer: Option (C) is the correct answer.

Step-by-step explanation:

In a chemical reaction the ratio between the amounts in moles of any two compounds is known as mole ration.

In the given reaction,
`2C_(2)H_(6) + 7O_(2)(g) \rightarrow 4CO_(2) + 6H_(2)O`

There are 7 moles of oxygen and 6 moles of water.

Thus, ratio of diatomic oxygen to water will be
`(7)/(6)`.
