Methyl salicylate (C₂H8O3) (density = 1.18 g/mL) is dissolved in 100 mL of 6.0 M NaOH, and heated for 15 minutes. The product, white crystals of salicylic acid (C7H6O3), is filtered, dried and weighed. Starting with 4.99 g of methyl salicylate, what is the theoretical yield of salicylic acid? Give your answer in 3 decimals.

Write a balanced equation for the reaction of hydroiodic acid, HI, with calcium hydroxide, Ca(OH)2. Then, write the balanced complete ionic equation and the net ionic equation for this neutralization reaction.
A titanium ore contains rutile (TiO2) plus some iron oxide and silica. When it is heated with carbon in the presence of chlorine, titanium tetrachloride, TiCl4, is formed. TiO2(s)+C(s)+2Cl2(g)TiCl4(g)+CO2(g) Titanium tetrachloride, a liquid, can be distilled from the mixture. If 35.4 g of titanium tetrachloride is recovered from 18.1 g of crude ore, what is the mass percentage of TiO2 in the ore (assuming all TiO2 reacts)?
You take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.
4.69 The pictures below show a molecular-scale view of a chemical reaction between H2 and CO to produce methanol, CH3OH. The box on the left represents the reactants at the instant of mixing, and the box on the right shows what is left once the reaction has gone to completion. Was there a limiting reactant in this reaction? If so, what was it? Write a balanced chemical equation for this reaction. As usual, your equation should use the smallest possible whole number coefficients for all substances.
The final step in the manufacture of platinum metal (for use in automotive catalytic converters and other products) is the reaction 3 (NH4)2PtCl6(s) 3 Pt(s) + 2 NH4Cl(s) + 2 N2(g) + 16 HCl(g) Complete this table of reaction quantities for the reaction of 12.35 g (NH4)2PtCl6.
4.107 Existing stockpiles of the refrigerant Freon-12, CF2Cl2 must be destroyed under the terms of the Montreal Protocol because of their potential for banning the ozone layer. One method for doing this involves reaction with sodium oxalate: CF 2 Cl 2 + 2Na 2 C 2 O 4 2NaF+2NaCl+C+ 4CO 2 S If you had 150 tons of Freon-12, describe how you would know how much sodium oxalate you would need to make that conversion.
