(a)
Interpretation: The given reaction,
Concept Introduction: The reaction that involves the loss of electrons or the addition of oxygen is oxidation. While that involves the gain of electrons or removal of oxygen is reduction.
(a)

Answer to Problem 34A
The balanced chemical equation is,
And, the first element,
Explanation of Solution
The given reaction,
It is a
The reaction is not balanced since the number of oxygen is not balanced on the product side. Oxygen can be balanced by adding two to
Therefore the balanced equation is,
The first substance in the reaction is barium,
(b)
Interpretation: The given reaction,
Concept Introduction: The reaction that involves the loss of electrons or the addition of oxygen is oxidation. While that involves the gain of electrons or removal of oxygen is reduction.
(b)

Answer to Problem 34A
The balanced chemical equation is
And, the first substance
Explanation of Solution
The given reaction,
It is a redox reaction that involves both oxidation and reduction. It can be represented as,
The reaction is a balanced equation since the number of copper, oxygen, and hydrogen is equal on both sides.
The first substance,
(c)
Interpretation: The given reaction,
Concept Introduction: The reaction that involves the loss of electrons or the addition of oxygen is oxidation. While that involves the gain of electrons or removal of oxygen is reduction.
(c)

Answer to Problem 34A
The balanced chemical equation is,
And the first substance
Explanation of Solution
The given reaction,
By following the oxidation number method the reduced and oxidized can be found. The oxidation number of carbon in
The oxidation number of
So, the balanced equation is,
The first species,
(d)

Answer to Problem 34A
The balanced chemical equation is
And, the first substance,
Explanation of Solution
The given reaction,
It is an example of a redox reaction. The oxidation number of aluminum is increasing from zero to +3 by the loss of three electrons. While the oxidation number of Ca is decreasing from +2 to 0 by accepting electrons. The electron count in the reaction can be balanced by adding two to aluminum and three to calcium.
The balanced half-reactions are,
So, the overall balanced equation is, a
