(a)
Interpretation: The given
Concept Introduction: A
A balance chemical reaction contains same number of atoms at both sides of the chemical reaction.
(a)
Answer to Problem 29A
Explanation of Solution
In a balance chemical equation, the number of atoms must be same at both sides. To balance a chemical reaction, coefficients must be added with the chemical formula to make it same at both sides.
Reactant | Product |
Fe = 1→2 | Fe = 2 |
S= 1→3 | S = 3 |
Thus the balance chemical equation must be:
(b)
Interpretation: The given oxidation-reduction reaction needs to be balanced.
Concept Introduction: A chemical reaction can be described as the process of conversion of reactant molecules to product molecules by breaking and making of chemical bonds.
A balance chemical reaction contains same number of atoms at both sides of the chemical reaction.
(b)
Answer to Problem 29A
Explanation of Solution
In a balance chemical equation, the number of atoms must be same at both sides. To balance a chemical reaction, coefficients must be added with the chemical formula to make it same at both sides.
Reactant | Product |
Zn = 1 | Zn = 1 |
N= 1→2 | N= 2 |
H=1→2 | H=2 |
O =3→6 | O = 6 |
Thus the balance chemical equation must be:
(c)
