NEET Chemistry Mole Concept MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Imagine a diagram showing a chemical equation for the combustion of methane: CH4(g) + 2O2(g) → CO2(g) + 2H2O(g). Which of the following correctly identifies the stoichiometric coefficients in this reaction?
A
1 for CH4, 2 for O2, 1 for CO2, 2 for H2O
B
1 for CH4, 1 for O2, 2 for CO2, 1 for H2O
C
2 for CH4, 1 for O2, 2 for CO2, 1 for H2O
D
1 for CH4, 2 for O2, 2 for CO2, 1 for H2O
Correct Answer
Option A
Detailed Explanation
The stoichiometric coefficients are the numbers in front of the chemical formulas in a balanced equation, representing the number of moles of each substance. In this reaction, the coefficients are 1 for CH4, 2 for O2, 1 for CO2, and 2 for H2O.
