Question

In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with which they can react. In the sandwich example, turkey, cheese, and mustard are available in excess. We deal with limiting reactant problems in our daily lives when we shop for food for recipes or pack outfits for a vacation. Likewise, with chemical reactions, if there is only a certain amount of one reactant avail- able for a reaction, it doesn't matter how much of the other reactants you have: The reaction must stop when the limiting reactant is consumed regardless of whether the other reactants have been used up. AG 5. Consider the chemical reaction given below: H (aq) OH (ag)- HO() moles of H,O a) If 1 mole of H (aq) reacts with 2 moles of OH (aq), how 1f H t 2 OH many ?H20 can be formed? 1 mol H 4 1 mol Ho 2 t Heo no beoid Bo %s:la owd eed b) What is the limiting reactant?

Answer 1

Ans I As it is I of the limiting will stop when all given reagent that the reaction is Consumed. H (ar) + okt (az) Hole) PPPPPPPPPPPPPPPPIN I Mole of it (as) reacts with 2 Mole of Orlar) here it is is limiting reagent. As soon as tt is Consumed the reaction will stop so at the end of reaction 1 Mole fort will be left as it is H₂O (0) More to initical point HW + on can I role amole Ht (ar) for (as) H₂O Mole o Mole 1 Mole e Ans how is the limiting reagent of Reaction,
