Answer:
As electro-negativity decreases from Florine to downwards in the group and only Florine is above Chlorine, so Florine should react with sodium chloride solution to produce chlorine.

Answer:
C: 1 mol F2/38 g F2
Explanation:
The reaction equation is;
N2 + 3F2 = 2NF3
Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;
105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2
Option C is Thus correct
Explanation:
(1.) A hydrophobic compound is defined as the compound that does not dissolve in water and they contain no charge. Hydrophobic compounds are generally organic in nature.
- As a result, there occurs no interaction between an ionic compound and hydrophobic compound. This is because ionic solvents or compounds are charged species and hydrophobic compounds do not contain any charge.
Hence, there occurs no interaction between the two.
- Whereas lower is the dielectric constant of a solvent, less polar it will be in nature. Hence, smaller is the value of a dielectric constant more readily and easily it is able to dissolve a hydrophobic compound.
- On the other hand, higher is the value of dielectric constant more polar the substance will be in nature. As a result, hydrophobic substance will not dissolve in high dielectric constant solvents and polar solvents such as water.
(2.) Pyrogen is defined as any substance that is able to cause fever. Bacterial pyrogens are endotoxins and exotoxins.
And, if both of these toxins are not removed from the body then they tend to interact with the mechanism of drug interaction and hence, these lead to unexpected side effects.
Therefore, the statement if formulating an aqueous solution for parenteral administration, filtered and sterile pyrogen free water must be used, is true.
