is always constant for a balance chemical equation:
ILLUSTRATIVE EXAMPLE (1):
ILLUSTRATIVE EXAMPLE (2):
ILLUSTRATIVE EXAMPLE (3):
ILLUSTRATIVE EXAMPLE (4): 367.5
gm KClO3 (122.5) when heated
then calculate.
(1) How many gram of O2 is produced?
(2)How Many litre of O2 is produced at STP?
SOLUTION:
ILLUSTRATIVE EXAMPLE (5): how many moles O2
are required to needed produced 5 moles of Fe2O3.
SOLUTION:
ILLUSTRATIVE EXAMPLE (6): how many grams of Fe2O3
formed by heating of 18 gm FeO with O2.
SOLUTION:
