Let X, Y be topological spaces, where X is compact and Y is Hausdorff. Let f be a continuous function in Homtop(X, Y). Then, we have cl(f(A)) = f(cl(A)). To prove this, we need to show that each set is contained in the other. How can we do this without using series, but only relying on the definitions of continuity, properties, Hausdorff, and compactness?

1. 2 Mg(s) + O₂(g) → 2 MgO(s) In the combustion of magnesium metal in oxygen gas (see the above equation), 6.73 g of magnesium and 8.15 g of oxygen gas are available for reaction. Identify the limiting reagent in this reaction. 2. Cu(s) + 2 AgNO3(aq) → 2 Ag(s) + Cu(NO3)2 (aq) In a reaction of copper metal with silver nitrate in solution, crystals of silver and copper(II) nitrate are formed according to the above equation. In a reaction, 10.0 g of copper is placed in a solution containing 20.0 g of silver nitrate. a) Identify the limiting reagent. Predict the mass of silver crystals formed. 3. HC₂H₂O2 + C₂H5OH → C4H10O2 + H2O If 30.0 g of butanoic acid (HC4H7O2) is mixed with 18.0 g of ethanol (C2H5OH), find a) the limiting reagent for the reaction. b) the mass of ethylbutanoate (C4H10O2) formed. 4. 4 FeS (s) + 7 O2 (g) → 2 Fe2O3 (s) + 4 SO2 (g) In an experiment, when 16.1 g of FeS reacted with 10.8 g of O2, 14.1 g of Fe2O3 (s) was produced according to the above equation. a) Identify the limiting reagent in the experiment. Calculate the theoretical yield. Calculate the percentage yield of Fe2O3 (s) in the experiment. 5. Fe2O3 (s) + 3 CO(g) → 2 Fe (s) + 3 CO2 (g) Iron is produced from its ore, hematite, Fe2O3(s), by heating with carbon monoxide in a blast furnace. If the industrial process produced 635 kg of iron from 1.00 tonne of hematite, what is the percentage yield of iron in the process? 6. In an experiment, 5.00 g of silver nitrate is added to a solution containing an excess of sodium bromide. It was found that 5.03 g of silver bromide is obtained. Write a balanced equation for the reaction. What is the theoretical yield of silver bromide? What is the actual yield of silver bromide in the experiment? What is the percentage yield of the experiment? 7. FeSAs (s) -> FeS (s) + As (s) Arsenates, used in some pesticides, are compounds of arsenic. The most common ore of arsenic, FeSAs (s), can be heated to produce arsenic according to the above equation. When 250 kg of the ore was processed industrially, 95.3 kg of arsenic was obtained. Calculate the percentage yield of arsenic in the process.
