Pure copper may be produced by the reaction of copper (I) sulfide with oxygen gas as follows: If the reaction of 0.730 kg of copper(l) sulfide with excess oxygen produces 0.140 kg of copper metal, what is the percent yield? 24.0 % 39.9 % 19.2% 48.0% 96.1% Which of the following compounds is insoluble in water? K_2CO_3 FeCO_3 Na_2CO_3 Li_2CO_3 (NH_4)_2CO_3. Which of the following would not be depicted as the individual ions on the reactant side of a complete ionic reaction? Mn(NO_3)_3 KOH HBr FeCO_3 Fe(NO_3)_2 Which of the following would not be depicted as the individual ions on the reactant side of complete ionic reaction? CsOH CH_3COOH HCI CoCl_2 MNBr_3 A precipitate is expected when an aqueous solution of lithium iodide solution of calcium nitrate. iron(II) chloride
