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.
Calculate the empirical formula of each compound with the following percent composition. (A) 94.1% O, 5.9% H 94.1 g O | 1 mole O = 5.88 moles O 5.9 g H | 1 mole H = 5.9 moles H | 16 g O | 1 g H 5.88 = 1 5. 9 = 1 5.88 5.88 Therefore, empirical formula is OH.. Write the formula and the name for the compounds formed from these pairs of substances. (A) barium and sulfur (B) calcium and nitrogen BaS; barium sulfide Ca3N2; calcium nitride (C) lithium and oxygen (D) copper (II) and iodine Li2O; lithium oxide CuI2; copper (II) iodide.
