← Acidified potassium dichromate oxidises hydrogen sulfide to sulfur. How many moles of H₂S are oxidised by 0.0840 mol of dichromate?Ammonium dichromate, (NH₄)₂Cr₂O₇, decomposes on heating to nitrogen, chromium(III) oxide and steam. What mass of solid Cr₂O₃ is left when 75.6 g of it is heated until it stops changing? The molar masses are 252 g/mol for the dichromate and 152 g/mol for Cr₂O₃. →
