d.
(a)
Interpretation:
Balance the following reaction by using inspection method.
Concept introduction:
Points for balancing the chemical equation:
- First, balance an element which occurs in only one compound present on both sides of the equation. Use fractions if required to balance an element.
- Then balance the atoms of element present in more amounts.
- In order to make fractions into whole number, use multiplication with suitable coefficient.
Answer to Problem 1E
The balanced equation is
Explanation of Solution
Given information:
The given equation is
Since, less number of atoms of sulfur is present in the equation so first balance sulfur atoms.
As per equation, number of sulfur atoms is equal on both sides.
Now, balance number of oxygen atoms.
To balance the oxygen atoms, multiply the oxygen molecule with half.
Multiply the whole equation with “2” to get co-efficient in whole number.
2× [
Thus, balanced equation is given by:
(b)

Answer to Problem 1E
The balanced chemical equation is:
Explanation of Solution
Given information:
The given equation is:
The more complex compound is Cl2O7, which has less common chlorine atom in it. So, balance chlorine atoms first.
The reactant side has two chlorine atoms and product has one chlorine atoms, so multiply
The above equation is balanced as number of oxygen and hydrogen atoms are equal on both sides.

Answer to Problem 1E
The balanced chemical equation is:
Explanation of Solution
Given information:
The given equation is
Since, least common atom is hydrogen atom so, first balance it on both the sides.
To balance hydrogen atoms, multiply
Now, balance the number of nitrogen atoms on both the sides by multiplying
Thus, above equation is balanced.
