Calculate the freezing point of a nonionizing antifreeze solution containing 388 g ethylene glycol, C2H6O2, and 510 g of water.

Replicate prove reliability and validity

The answer is fossil fuels.

Carbon is found in all living organisms. the constant flow of carbon on earth through organisms and the air is known as the carbon cycle. plants absorb carbon from the atmosphere in the form of carbon dioxide. they use it for respiration and  convert it into simple sugars by  photosynthesis  process. animals consume plants, transferring carbon along the food chain. plants and animals respire and release carbon into air. when the animals and plants die, they are eaten by microorganisms. carbon enters back into the atmosphere in the form of  carbon dioxide.
