Describes a molecule in which the positive and negative charges are separated HELP ME PLEASE !!

Polar

Explanation:

Polar is a concept which explains the formation of a particular molecule as a result of a separation of electric charges. In such molecule formed, there is a negatively charged end and a positively charged end. The difference in their electronegativity is what determines the strength of the bind formed in the molecule.

Electrically charges object can be used to attract molecules that are polar. This is because, when polar molecules are placed in an electric field, the positive charged end tends to align with the negative plate while the negatively charged end tends to align with the positive end.

Examples of polar molecules are water, hydrogen sulphide, ethanol, and some others.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
