limiting reagent

The reactant which is entirely consumed in reaction is known as limiting reagent. In the reaction 2A+4Brarr3C+4D , when 5 moles of A react with 6 moles of B, then (a) which is the limiting reagent? (b) calculate the amount of C formed?

Many a time the reaction are carried out when the reactants are not present in the amounts required by a balanced chemical reaction. In such situations, one reactant is in excess over other. The reactant which is present in th lesser amount gets conserved after sometime and after that no further reaction takes place whatever be the amount of other reactant is present .Hence, the reactant which gets consumed , limits the amount of products formed and is therefore called limiting reagent. To determine the limiting reagent find the value of phi which is the ratio of (given) mole of a substance to the stoichiometric coefficient of that substance . The limiting reagent is the reagent which has minimum value of phi . In the above question , how much reactant is remaining at the completion of reaction and which one?

In the following questions , a statement of assertion (A) is followed by a statement of reason (R). A: When 4 g of NaOH is added to 100 mL of 1 M H_2SO_4 then 0.05 mole of Na_2 SO_4 is produced. R: NaOH is the limiting reagent in above reaction

How much magnesium sulphide can be obtained from 2.00 g of Mg and 2.00 g of S by the reaction. Mg + S rarr MgS . Which is the limiting reagent? Calculate the amount of one of the reactants which remains unreacted?

The limiting reagent is the reagent which has minimum value of phi . The insecticide DDT is made by the reaction CClCHO("Chloral")+2C_(6)H_(5)Cl (chlorobenzene) rarr (ClC_(6)H_(4))_(2) CHCCl_(3)(DDT)+H_(2)O If 100 pound (lb) of chlorobenzene , how much DDT would be formed? (Assume the reaction goes to completion without side reactions or losses) [1 lb =453.6 g]

The reaction is : 2Al +Cr_(2)O_(3) rarr Al_(2)O_(3) +2Cr How much metallic chromium can be made by bringing to reaction temperature a mixture of 5 kg Al and 20 kg Cr_(2)O_(3) ?
