In reaction A+2B---C 4 moles of A and 10 moles of B will produce:
Correct answer: A. 4 moles of C
- A. 4 moles of C
- B. 5 moles of C
- C. 8 moles of C
- D. None of these
Explanation
The stoichiometric coefficients tell us the molar ratios between the reactants and products. It indicates that for every one mole of A, we need 2 moles of B to produce the products.Now, as mentioned that we have 4 moles of A and 10 moles of B. To determine how much C will be produced, we need to use the stoichiometry of the reaction.according to equation A is acting as the limiting reagent so do calculations using A1A = 1C Hence 4A = 4C

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.
