Summary:
- Carbon can form two different compounds with oxygen.
- The law of multiple proportions states that whenever the same two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.
- Carbon dioxide fire extinguishers cut off the flow of oxygen in a fire, putting out the fire.
- Carbon monoxide is a deadly gas, formed from the incomplete combustion of some carbon-containing materials (such as wood and gasoline)
