Question

(a) Rusting and respiration are also combustion reactions. Explain.
(b) Why is CO, considered to be an excellent fire extinguisher? Give reasons​

Answer 1

Answer:

1)Rust is another name for iron oxide which occurs when iron is exposed to oxygen and moisture for a long period of time. Overtime the oxygen combines with the metal at atomic level forming a compound called an oxide. Rust forms when iron undergoes oxidation. The main catalyst for the rusting process is water.

2)The carbon dioxide considered the best fire extinguisher to put off fires caused by burning of inflammable liquids such as petrol or oil because carbon dioxide stops the influence of oxygen because it decreases the oxygen present in that fire which leads to the fallout of fire.
