NASA Ames Research Center shared SOFIA Stratospheric Observatory for Infrared Astronomy's video. Welcome back to California, SOFIA Stratospheric Observatory for Infrared Astronomy!! We're back at NASA's Armstrong Flight Research Center after six weeks observing the southern skies from Christchurch, New Zealand.
Report Abuse. Calcium is an element with an ion charge/oxidation number of 2+. Carbonate is a polyatomic ion with an ion charge of 2-. Since the two ion charges cancel out or equal zero, the formula would be CaCO3(the three is a subscript.) the Ca is the symbol for Calcium and the formula for carbonate is CO3.blah Â· 9 years ago.Thumbs up.arbonate is a polyatomic ion with an ion charge of 2-.

The calcium and magnesium hardness is the concentration of calcium and magnesium ions expressed as equivalent of calcium carbonate. Total permanent water hardness expressed as equivalent of CaCO3 can be calculated with the following formula: Total Permanent Hardness (CaCO3) = 2.5(Ca2+) + 4.1(Mg2+).
