Question
N29 n30. If 4.0 g of H 2 react with 4.0 g of F2 in the reaction shown below, what is the limiting reactant? H2 + F2 rightarrow 2 HF. Reaction of A (unshaded spheres) with B2 (shaded spheres) is shown schematically in the following diagram Which equation best describes the stoichiometry of the reaction? The following diagram represents the reaction of A, (unshaded spheres) with B (shaded spheres) What is the balanced chemical equation for this reaction, and what is the limiting reactant? 2A2 + B rightarrow A4 B; A2 is the limiting reactant. 4A2 + 6B rightarrow 2 A4 B; B is the limiting reactant. 4A2 + 6B rightarrow 2A4B; A, is the limiting reactant.Explanation / Answer
28. F2 is limiting reagent it is present in lesser quantity in the reaction.
29 . 4A +B2 ------------> A4 B2
29. 4A2 + 6B ----------------> 2A4B : A2 is limiting reagent.
in any chemical reaction reactant which completes completely is called limiting reagent.
