Which of the following actions would decrease global warming? Select one:
Decreasing the amount of methane in the air.

Increasing the amount of oxygen in the air.

Increasing the amount of water vapor in the air.

Decreasing the amount of nitrogen in the air.

Decreasing the amount of methane in the air

Explanation:

Methane traps heat inside the earth's atmosphere. It allows the heat to enter, but not exit, therefore making the earth warmer.

Decreasing the amount of methane in the air

Explanation:

Methane is a powerful greenhouse gas, which absorbs the sun's heat and doesn't allow it to escape therefore contributing to global warming

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
