Carbon dioxide levels in the beginning of the industrial revolution was about 280 ppm (parts per million). if carbon dioxide levels have increased 38%, how much carbon dioxide is now in the atmosphere?

10640

737 ppm

8960 ppm

386 ppm

The level of carbon dioxide in the now is

Explanation:

It is given that carbon dioxide at the beginning of industrial revolution is . It then increased by 38%.

Thus the current amount of carbon dioxide is

Increasing carbon dioxide level is a growing concern. It is a result of industrialization and urbanization which has serious consequences. Increased level of carbon dioxide accelerates global warming and it increases the temperature of earth.

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.
