How many moles of CO2 are produced from 0.9 moles of O2 in the reaction C + O2 -> CO2:
Correct answer: A. 0.9 mole
- A. 0.9 mole
- B. 36 moles
- C. 1.8 moles
- D. 3.6 moles
Explanation
To summarize, the correct answer is option A) 0.9 mole of CO2.If 0.9 moles of O2 react, we need to determine the stoichiometric ratio between O2 and CO2 in the balanced equation. From the balanced equation, we can see that the coefficient of O2 is 1, and the coefficient of CO2 is also 1. This means that for every mole of O2 reacted, we will produce an equal number of moles of CO2. Therefore, the answer is 0.9 moles of CO2.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
