 Enthalpy of Hydration of Sulfuric Acid  Enthalpy of Hydration of Sulfuric Acid 1. The hydration reaction can be expressed in several manners. Write a chemical reaction that shows undissociated sulfuric acid reacting with water to form HSO_4 (aq) and hydronium ions H_3 O^+.  2. From the initial and final volumes of sulfuric acid in the 10 mL graduated cylinder, calculate the volume of sulfuric acid added to the calorimeter.  3. Use the volume of sulfuric added to the calorimeter, the density of concentrated sulfuric acid (1.8 g/mL), and its purity (98%) to calculate the mass of H_2 SO_4 placed in the calorimeter. By adding the mass of 98% sulfuric acid and the mass of water (density of water is 1.00 g/mL) in the calorimeter, calculate the total mass of solution in the calorimeter.  4. From the mass of added sulfuric acid and the molar mass of the acid, calculate the number of moles of sulfuric acid added to the calorimeter.  5. By using Equation (11-5) with the i

Experiment Heat of Combustion: Magnesium In Experiment 18, you learned about the additivity of reaction heats as you confirmed Hess's Law. In this experiment, you will use this principle as you determine a heat of reaction that would be difficult to obtain by direct measurement- the heat of combustion of magnesium ribbon. The reaction is represented by the equation This equation can be obtained by combining equations (1),(2), and (3): bt ,0r、6Mnoe eeder.30n Δ1/uol rl@-14.70s ebetat (1) MgO(s) + 2 HCI(aq)-→ MgCldaq) + H2O(l) 20(1) -S714" &WnmMgz-20-16 (2) (3) Mg (s) +2 HCI(aq) H2(g) + --MgCl2(aq) + H2 (g) -→H2O(l) - 1/2 Oz(g) The pre-lab portion of this experiment requires you to combine equations (1), (2), and (3) to obtain equation (4) before you do the experiment. Heats of reaction for equations (1) and (2) will be determined in this experiment. As you may already know, AH for reaction (3) is-285.8 k.J. OBJECTIVES In this experiment, you will △H Combine three chemical eq

Two insulated wires perpendicular to each other in the same plane carry currents as shown in the figure. 1. Find the magnitude of the net magnetic field these wires produce at points P and Q if the 10.0 A   current is to the right. 2. Find  the magnitude of the net magnetic field these wires produce at points P and Q if the 10.0 A   current is to the left.
