Mr. Swerdlow wrote a chemical equation on the board and asked his class what should be changed to make it correct. He wrote: water + carbon dioxide → glucose + oxygen + energy What should be changed to show the correct chemical reaction? A). Carbon dioxide should be traded with glucose, and energy should be shown on both sides.
B). Water should by moved to the products side, and glucose and oxygen should both be moved to the reactants side.
C). Water and carbon dioxide should both be moved to the products side, and glucose and oxygen should be moved to the reactants side.
D). Glucose should be moved to the reactants side, and water and carbon dioxide should both be moved to the products side.

C. Water and carbon dioxide should both be moved to the products side, and glucose and oxygen should be moved to the reactants side.

Explanation:

4.) metal

"-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."
