Why do different metal ions emit different colors of light? Because lectrons gain energy and can be excited into any of the empty higher-energy orbitals. O Because electrons at higher and more energetically unstable levels fall back down to the original level, but not necessarily in one transition. O Because each element has a different number of electrons, a different set of energy levels, which creates a unique emission spectrum. O Because metal ions create unique frequency patterns of light that are visible by the naked eye. Question 4 Find the formula and name of the hydrate of CaSO, if it contains 23.1% water by mass. Molar mass of water is 18.02 g/mol. Molar mass of CaSO, is 120.17 g/mol. How many waters are associated with one unit of CaSO,? 1 pts Give the full name of the hydrate of CaSO,. words or suffixes. You answer is not case sensitive (upper and lower case does not matter). Your answer should be a single digit number. Your answers should not include any extra spaces between
