Answer: The density of the given vapor is 0.939 g/L.
Explanation:
Given: Pressure = 233 mm Hg (1 mm Hg = 0.00131579 atm) = 0.31 atm
Temperature = 
= (25 + 273) K = 298 K
According to the ideal gas equation,
where,
P = pressure
V = volume
m = mass
M = molar mass
R = gas constant = 0.0821 L atm/mol K
T = temperature
This formula can be re-written as follows.
(where, 
)
Hence, formula used to calculate density of diethy ether (molar mass = 74.12 g/mol) vapor is as follows.
Substitute values into the above formula as follows.
Thus, we can conclude that the density of the given vapor is 0.939 g/L.
In a polar covalent bond, there is an unequal sharing of electrons between atoms. If there is equal sharing otherswise it is considered polar covalent. The answer for 1) is D. Water has a higher boiling point because of the strong attraction between polar water molecules due to hydrogen bonding. Answer for 2 is D.
Answer:
They both have letters and different formulas to find the answer.
Explanation:
Answer:
The correct answer is B the tertiary halides reacts faster than primary halides.
Explanation:
During SN2 reaction the nucleophile attack the alkyl halide from the opposite side resulting in the formation of transition state in which a bond is not completely broken or a new bond is not completely formed.
After a certain period of time the nucleophile attach with the substrate by substituting the existing nuclophile.
An increase in the bulkiness in the alkyl halide the SN2 reaction rate of that alkyl halide decreases.This phenomenon is called steric hindrance.
So from that point of view the that statement tertiary halides reacts faster that secondary halide is not correct.
