Give the empirical formula of each of these compounds.
Answer to relevant QuestionsDetermine the molecular formulas to which the following empirical formulas and molar masses pertain. a. SNH (188.35 g/ mol) b. NPCl2 (347.64 g/ mol) c. CoC4O4 (341.94 g/ mol) d. SN (184.32 g/ mol) A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157 g of the compound produced 0.213 g of CO2 and 0.0310 g of H2O. In another experiment, 0.103 g of the compound produced 0.0230 g of NH3. ...The element europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 amu, and 153Eu has a mass of 152.9209 amu. The average atomic mass of europium is 151.96 amu. Calculate the relative abundance of the two ...Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid- fuel rocket motors. The reaction is Fe2O3(s) + 2Al(s) → 2Fe(l) + Al2O3(s) What masses of iron(III) ...Hydrogen peroxide is used as a cleaning agent in the treatment of cuts and abrasions for several reasons. It is an oxidizing agent that can directly kill many microorganisms; it decomposes upon contact with blood, releasing ...
