Chemical nomenclature Therefore, the name of the compound is calcium hydroxide. If one is asked to write the formula for copper(I) chromate, the Roman numeral indicates that copper ion is Cu and one can identify that the compound contains the chromate ion (). Two of the 1+ copper ions are needed to balance the charge of one 2− chromate ion, so the formula is CuCrO. Type-III binary compounds are covalently bonded. Covalent bonding occurs between nonmetal elements. Covalently-bonded compounds are also known as "molecules". In the compound, the first element is named first and with its full elemental name. The second element
CU Spaceflight offer to do so, hoping to raise the profile of engineering and aerospace in particular. During the 2007 Cambridge Science Festival, CU Spaceflight launched their Nova 5 balloon in front of a large crowd. CU Spaceflight CU Spaceflight is a student-run Cambridge University society founded with the aim of achieving cheap access to space. It is supported by the Cambridge-MIT Institute. The project was founded in the summer of 2006, with the specific goal of launching a rocket into space for less than GBP£1000. As of November, 2007, CU Spaceflight has launched five uncrewed high-altitude balloons, of which two were
