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 convoys anti-submarine screens for CU convoys because the s of the British and Canadian Mid-Ocean Escort Force were not fast enough to maneuver with these convoys. Nine tankers departed Curaçao as convoy CU 1 on 20 March 1943 and arrived in Liverpool on 1 April. Additional sailings from Curaçao were CU 2 in June, CU 3 in July, CU 4 in September, and CU 6 in November. Convoy CU 5 was the first to originate in New York on 13 October 1943. Approximately three or four CU convoys sailed from New York each month from December 1943 through May 1945. Convoys
