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.
Barium is an element in Group 2, so it has two valence electrons, and that it's charge is 2+. Hydroxide is a polyatomic negative ion with a valency of 1, and that it's charge is 1-. As barium is a metal while hydroxide is a non-metal, they combine to form an ionic compound. To form a neutral compound, balance the positive and negative charges by applying LCM,and the number of positive and negative charges must be equal. Ba^(2+) and (OH)^(2-) Ba^(2+) (OH)^(2-) (OH)^(2-) As seen from above, one barium ion and two hydroxide ions form barium hydroxide.
