Essentially it is a competition between metal(1) and metal(2) for oxygen in a reaction represented by: Metal(1) + Metal(2) oxide → Metal(1) oxide + Metal(2) The more reactive metal displaces the less reactive metal from its oxide, as in the case of zinc and copper(II) oxide, … They have properties in common, but they also differ in significant respects. Molar mass of Zinc = 65.38 g/mol. www.njctl.org Chemistry Ionic Bonding 41. Zinc Nitrite Chemical Formula. ZnO_2 With all these problems, we assume that there are 100*g of unknown compound, and then we proceed to calculate the empirical formula: "Moles of zinc" = (67.1*g)/(65.4*g*mol^-1)=1.03*mol "Moles of oxygen" = (32.9*g)/(15.999*g*mol^-1)=2.06*mol Given the molar ratios, we divide thru by the lowest molar quantity to get an empirical formula of ZnO_2. chemical formula of (a) zinc and oxygen (b) magnesium and nitrogen (c) carbon hydrogen on the 7th question - Science - Atoms and Molecules Now we have two oxygen atoms on each side of the equation, but our added 2 increases the number of H atoms on the right to four at the same time that it increases the number of O atoms to two. For example: Sodium plus oxygen would produce Sodium oxide, Bismuth and Oxygen would produce Bismuth oxide, Zinc plus … In dry air, zinc is slowly attacked by atmospheric oxygen. The formula for this compound indicates it contains Al 3+ and SO 4 2− ions combined in a 2:3 ratio.
