Stoichiometry
In the reaction, Ca + 2H₂O = Ca(OH)₂ + H₂ ; what volume (c.c.) of hydrogen at STP would be liberated, when 8 gm of calcium reacts with excess water? (atomic weight of calcium = 40)
Recycling in a process stream helps in utilising the valuable reactants to the maximum with minimum loss of reactants
Recycling in a process does not help in getting higher extent of reaction
Recycling is exemplified by refluxing back a part of the distillate to the distillation column to maintain the quantity of liquid within the column
The ratio of the quantity of a reactant present in the reactor feed of a recycling operation to the quantity of the same reactant entering the process as fresh feed is called combined feed ratio
