Explain how Co2 is able to control fires?<br><img src="https://tex.z-dn.net/?f=co2" id="TexFormula1" title="co2" alt="co2" align
Alborosie

Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.

Further Explanation:

In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.

CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.

Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.

What is the journey of a pice of cheese through your digestive system. Starting with the stomach and ending with absorption. Inc
allochka39001 [22]
Cheese is composed of fats and proteins. On reaching the stomach gastric juice is produced, which contains pepsin that acts on proteins to form dipeptides. In the duodenum, enzymes trypsin and chymotrypsin released from the pancrease acts on dipeptides to produce peptides. Bile juice from the bile acts on fats to form small fats droplets a process called emulsification. In the small intestines enzyme peptidase acts on peptides to form amino acids, while enzyme lipase acts on fat droplets to produce fatty acids and glycerol. Amino acids, fatty acids and glycerol are then absorbed into the blood stream.
