Carbon dioxide is an integral part of the carbon cycle, a biogeochemical cycle in which carbon is exchanged between the Earth's oceans, soil, rocks and biosphere.econstructions show that concentrations of CO 2 in the atmosphere have varied, ranging from as high as 7,000 parts per million during the Cambrian period about 500 million years ago to as low as 180 parts per million during the Quaternary glaciation of the last two million years.
Barium chlorate. Barium chlorate, Ba(ClO3)2, is a white crystalline solid, the barium salt of chloric acid. It is an irritant and toxic, as are all soluble barium compounds. It is sometimes used in pyrotechnics to produce a green color. It also finds use in the production of chloric acid.
Note from its formula that barium nitrate contains the Ba(2+) and N03(-) ions. In virtually every case when a solid containing ions dissolves in water, the ions separate and move around independently. That is, Ba(NO3)2(aq) does not contain Ba(NO3)2 units. Rather, it contains separated Ba(2+) and N03(-) ions.In the solution, there are two N03(-) ions for each Ba(2+) ion. Barium nitrate is a strong electrolyte in water, as each Ba(NO3)2 unit produces the separated ions [Ba(2+), N03-, N03-].Similarly, aqueous K2CrO4 also behaves as a strong electrolyte.n the solution, there are two N03(-) ions for each Ba(2+) ion.
