Metallic silver was produced by thermal decomposition of 1.252 g of silver(I) oxide.
Calculate to 3 significant figures the number of moles of oxygen produced.
Calculate to 2 significant figures the atom economy of this reaction if silver is the desired product.
Thermal decomposition of barium peroxide produced 2.500 kg of barium oxide.
Calculate the number of moles of oxygen produced to three significant figures.
Calculate the atom economy of this reaction, to two significant figures, if barium oxide is the desired product.
Silver is formed by reacting 35.27 g potassium argentocyanide with excess zinc. Zinc(II) cyanide and potassium cyanide are the only by-products.
Calculate the number of molecules of zinc reacted.
Calculate the mass of potassium cyanide produced.
Calculate the atom economy for this method of silver production, to 2 significant figures.
