What is the chemical formula for chromium(III) oxide?
2016年7月26日 · "Cr"_2"O"_3 The first thing to notice here is that you're dealing with an ionic compound that contains chromium, "Cr", a transition metal, and oxygen, "O", a non-metal. The interesting thing about this compound is that it contains a transition metal as its cation, i.e. its positively charged ion. As you know, the name of a transition metal cation is written using …
Writing Ionic Formulas - Chemistry - Socratic
Writing ionic formulas requires knowing the charges of ions in the compound. In general, the charge of the positive ion is written on the negative ion and the charge of the negative ion is written on the positive ion creating a cross-over. For example, if the Calcium ion is +2 and Chloride ion is -1, then Calcium Chloride is written CaCl2.
On heating ammonium dichromate, the gas evolved is?
2017年8月5日 · The chromium(III) oxide crystals are "fluffier" than the original ammonium dichromate. Thus, even though much of the mass of the starting material escapes as nitrogen gas and water vapour, the product looks like a much larger amount of material.
