Answer:
Option B
Explanation:
The image for the question is attached herewith
Solution
The curve B represents gas curve at room temperature while C represents the gas curve for hot temperature and curve A represents gas curve for gas at cold temperature
The number of particles in hot gases are sparsely distributed and the energy of particles is high as compared to the energy of particles at room temperature and cool temperature.
Hence, option B is correct
Answer: The mole ratio of sodium to sodium chloride 2:2.
Explanation:
As the given reaction equation is as follows.
Here, 2 moles of sodium reacts with 1 mole of and leads to the formation of 2 moles of NaCl.
This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.
Hence, the ratio of moles of sodium to sodium chloride is 2:2.
Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.
