    Carbon dioxide - Wikipedia

    Carbon dioxide is the lasing medium in a carbon dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.

    from coal combustion are primarily sulfur dioxide (SO 2), with a much lower quantity of sulfur trioxide (SO 3) and gaseous sulfates. These compounds form as the organic and pyritic sulfur in the coal are oxidized during the combustion process. On average, about 95 percent of the sulfur present in bituminous coal will be emitted as gaseous SO x
