Who can witness a lunar eclipse? people in the specific area of earth’s surface covered by the moon’s shadow all people on the night side of earth all people on the day side of earth people in a specific area of earth’s surface covered by the sun’s shadow people living on the poles

all people on the night side of Earth

Explanation:

Lunar eclipse, also known as eclipse of the moon is a phenomenon that takes place when the sun, the earth and the moon are closely aligned. The earth comes in-between the moon and the sun, blocking the rays of the sun from reaching the moon in the process.

The eclipse which can only happen on a night with full moon makes the moon to appear faded or appear or reddish in color (blood moon).

Lunar eclipse can be viewed by anyone that is on the night side of the earth when the event occur, although viewing it requires some efforts

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
