Which of the following molecule(s) is (are) polar? co2, ch4, cbr4, or chbr3

Option (d) is the correct answer.

Explanation:

Polarity in a molecule arises due to unequal sharing of electrons. More is the difference in number of sharing of electrons more will be the polarity of a molecule.

In a molecule there is a linear geometry and two oxygen atoms equally pull the valence electrons from carbon atom. So, it means is a non-polar molecule.

In , there will be equal sharing of valence electrons between both carbon and hydrogen atoms. Also, bond dipoles will equally cancel out each other. Hence, methane is also non-polar in nature.

is a symmetrical molecule and its bond dipoles will be cancelled out. Hence, it is also non-polar in nature.

In , the C-Br bond is polar in nature and this molecule is unsymmetrical in nature. Hence, this molecule will be polar in nature.

Thus, we can conclude that out of the given options molecule is polar.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
