(a)
Interpretation: The balanced chemical equation of the heating of solid barium chlorate that results in the formation of barium chloride and gaseous oxygen is to be determined.
Concept Introduction: Chemical equations can be balanced by equalizing the atoms present on the reactant and product side.
(a)
Answer to Problem 59A
The balanced chemical equation is,
Explanation of Solution
The heating of solid barium chlorate,
reaction:
Now, check whether all the elements involved are equal on both sides. The number of oxygen is not equal, so, it can be equalized by multiplying 3 by the
(b)
Interpretation: The balanced chemical equation of solid lead(II) sulfide with gaseous oxygen, which results in the formation of solid lead(II) oxide and gaseous sulfur dioxide is to be determined.
Concept Introduction: Chemical equations can be balanced by equalizing the atoms present on the reactant and product side.
(b)
Answer to Problem 59A
The balanced chemical equation is
Explanation of Solution
The reaction of lead(II) sulfide with gaseous oxygen, results in the formation of solid lead(II) oxide and gaseous sulfur dioxide can be written as,
The reaction is not in a balanced form since the oxygen count is not equal. It can be made equal by adding 3 to O2, 2 to
