(a)
Interpretation: The given synthesis reaction needs to be balanced.
Concept Introduction: A
A balance chemical reaction contains same number of atoms at both sides of the chemical reaction.
(a)
Answer to Problem 38A
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 |
Co = 1→2 | Co = 2 |
S = 1→ 3 | S = 3 |
Thus the balance chemical equation must be:
(b)
Interpretation: The given synthesis 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 38A
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 |
N = 1→ 2 | N = 2 |
O = 3→4 | O = 4 |
Thus the balance chemical equation must be:
