6 0

B) H₂

Explanation:

Only H₂ is a non-polar covalent molecule among the given options. A non-polar covalent bond forms between homonuclear atoms that are chemically bonded.

  • In the formation of covalent bonds, each atom shares the valence electrons in their outer energy shells to be able to mimic the noble gases.
  • In homonuclear molecules, the two bonding atoms are of the same kind and the electronegativity difference is zero.
  • The covalent bond between them is a called a non-polar covalent bond.
  • Here there is equal sharing of the electron pair between the pair of atoms and there is no electrostatic charge on the molecule.

An atom of which element has the greatest attraction for electrons in a chemical bond?
Katyanochek1 [597]
Answer is (4) - Se.

Among the given choices Se has the highest electronegativity value as 2.4 compared to others. Hence, Se shows <span>greatest attraction for electrons in a chemical bond.

</span>Electronegativity is a value that tells us how an atom can attract electrons towards itself. <span>If the electronegativity is high, then the attraction to the electrons is also high.

Which is a problem associated with the use of trees for biomass? I. Potential deforestation II. Burning fossil carbon III. Poten
BigorU [14]

Answer:

Both Option (I) and Option (III)

Explanation:

Biomass is usually defined as those organic molecules that are obtained from plants and animals, in order to produce energy. It is a renewable resource. Some of the examples of biomass include wood, crop, animal fossil fuel.

A large number of trees are being cut down to construct these biomass energies such as woods. This results in the deforestation process where the forested areas are converted into empty dry soils. This results in the increasing rate of erosion because the prevailing wind and flowing water can easily carry away the topsoil and loses the fertility of the soil.

Thus, the correct answers are both options (I) and (III).

Individual particles move with the wave.
MArishka [77]

Answer:

No.

Explanation:

No, individual particles do not move with the wave, it only oscillates back and forth its mean position. The particles in the medium transfer its energy to their neighboring particles and in that way the energy moves in the form of wave. The particles only vibrates on its means position instead of moving from one place to another. So we can conclude that Individual particles do not move with the wave.
