Which statement best describes the polarity of CH2Cl2? View Available Hint(s) Which statement best describes the polarity of ? T
1 answer:
Answer: Option (a) is the correct answer.
Explanation:
The compound is tetrahedral in nature. But due to difference in electronegativity of both carbon and chlorine, chlorine is more electronegative than carbon.
Whereas carbon is more electronegative than hydrogen atom.
As a result, there will be individual bond moment which is unequal and leads to net dipole moment into the molecule.
Hence, the compound will always be polar in nature.
Thus, we can conclude that the statement molecule is always polar, describes the polarity of .

Answer:
Explanation: A double displacement reaction is one in which exchange of ions take place.
The compounds which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
Thus the exchange of ions take place and all the compounds are soluble so the chemical formulas are followed by the symbol (aq).
Answer: 7.693 L
Explanation:
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Thus new volume of the gas is 7.693 L
