Bacteria multiply through binary fission. This process involves the division of a single cell into two identical daughter cells, and it starts when the DNA of a bacterium divides into two replicates. The bacterial cell splits into two daughter cells that have identical DNA to the parent cell.
The statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2
From the question,
We are to determine which of the given statements is true.
From the given reactions,
We have
1. N2 (g) + O2 (g) ----> 2NO (g) ΔH1
and
2. 1/2 N2 (g) + 1/2 O2 (g) ---> NO (g) ΔH2
ΔH1 is the enthalpy change for reaction 1
and
ΔH2 is the enthalpy change for reaction 2
Enthalpy is an extensive property. The enthalpy change for a given reaction depends on the stoichiometry of the reaction.
From the given equations,
We can observe that the stoichiometry of reaction 1 is twice that of reaction 2.
Therefore, the enthalpy of reaction 1 will also be twice the enthalpy of reaction 2
That is,
ΔH1 = 2ΔH2
Hence, the statement that is true among the given statements is ΔH1 = 2ΔH2. The correct option is d. ΔH1 = 2ΔH2

Answer:
Explanation:
To solve the problem, we must know the kind of compounds we are dealing with.
For the first compound, P1 and second compound P2:
N O N O
Mass percent 64.17 35.73 47.23 52.79
Atomic mass 14 16 14 16
Number of
moles 64.17/14 35.73/16 47.23/14 52.79/16
4.58 2.23 3.37 3.30
Simplest
ratio 4.58/2.23 2.23/2.23 3.37/3.30 3.3/3.3
2 1 1 1
P1 compound is N₂O
P2 compound is NO
These are the compounds,
In N₂O = 28:16
NO = 14:16
This is the ratio of nitrogen to a fixed mass of oxygen for the two compounds.
