3. The following acid and base solutions are placed in a calorimeter at constant pressure: 50.0 mL of 0.20 M HCl and 50.0 mL of 0.30 M NaOH. The water in the mixture has a specific heat of 4.184 J/g C. The water is initially at 21.0 C and at the end of the reaction is at 24.7 C. a. Write the balanced chemical equation for the reaction. Include states of matter. b. Calculate the heat q for this reaction using the calorimetry equation. Assume the density of each solution is 1.0 g/mL (d=m/V). C. Calculate the number of moles of HCl used in the reaction. d. Calculate the moles of NaOH used in the reaction. e. Use the relation q +4H = 0 to find the enthalpy change for the reaction f. Find the molar heat of reaction by using AH/n where n is the number of moles of the limiting reactant. Recall that the limiting reactant is the reactant that produces the smaller amount of products in a reaction. Enter

O MATTER Solving applied density problems Mr. Auric Goldfinger, criminal mastermind, intends to smuggle several tons of gold across international borders by disguising it as lumps of iron ore. He commands his engineer minions to form the gold into little spheres with a diameter of exactly 6 cm and paint them black. However, his chief engineer points out that customs officials will surely notice the unusual weight of the "iron 3. ore" if the balls are made of solid gold (density 19.3 g/cm). He suggests forming the gold into hollow balls 3. instead (see sketch at right), so that the fake "iron ore" has the same density as real iron ore (5.15 g/cm). One of the balls of fake "iron ore," sliced in half. Calculate the required thickness of the walls of each hollow…
