How can carbon dioxide be collected?

Answer 1

It everywhere in the air. In fact is takes up about 50% of the earth's atmosphere. Everytime you exhale, you are releasing carbon dioxide into the air while plants take this in for photosynthesis.

Answer 2

· From fractional distillation of air

· As a by-product of hydrogen production plants, where methane is converted to CO2

· As a by-product of fermentation of sugar in the brewing of beer, whiskey and other Alcoholic Beverages

· From thermal decomposition of limestone, CaCO3, in the manufacture of lime, CaO

· As a by-product of sodium phosphate manufacture

· Directly from natural carbon dioxide springs, where it is produced by the action of acidified water on limestone or dolomite.

· From combustion of fossil fuels and wood.

Answer 3

Carbon Dioxide(CO2) is more than dense than air and hence can be colleted by two methods. (i.) In Downward Delivery method, a gas jar is connected to the flask by a tube that is giving off the gas. The more dense gas fall to the bottom of the jar and displaces the air and the gas is collected in the jar. (ii.)CO2 can also be collected using the syringe. The syringe is connected by a tube to the flask that is giving off the gas. The gas syringe has marks along its length which measures the volume collected. As the volume of gas increases, the plunger moves out of the syringe and the gas is collected in it. The more the volume of gas, the more the plunger gets out of the syringe.

Answer 4

It's in the air all around you. It comes from the trees and every thing that breathes on earth.
