Cobalt(II) carbonate Like most transition metal carbonates, cobalt carbonate is insoluble in water, but is readily attacked by mineral acids: Cobalt carbonate is a precursor to cobalt carbonyl and various cobalt salts. It is a component of dietary supplements since cobalt is an essential element. It is a precursor to blue pottery glazes, famously in the case of Delftware. The moderately rare spherocobaltite is the natural form of cobalt carbonate, with good specimens coming especially from the Republic of Congo. "Cobaltocalcite" is a name used for a cobaltiferous calcite variety that is quite similar in habit to spherocobaltite. The compound is harmful
Element Hunters their own concerns, Ren, Chiara, and Homi, three average middle school students from Earth, banded together to also become Element Hunters. With the help of Professor Aimee Carr and Juno, they are able to help save their own planet. The team made up of children who have the ability to go to "Nega Earth." They are taken from Earth early in their lives and trained in the Space Colony to become Element Hunters. Element Hunters In the year 2029, chemical elements such as oxygen, carbon, gold, molybdenum, and cobalt were continually disappearing from Earth. These disappearing elements ultimately disrupted the
