The Heat of Formation of Magnesium Oxide CHEM 1411 EXPERIMENT Lab Report Assignment Type your answers into this assignment and submit the saved document through eCampus. Pre-Lab Questions In determining the Heat of Formation of MgO, you will be using Hess' Law. You will be using the three following reactions: Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) (Eqn.1) MgO(s) + 2HCl(aq) → MgCl2(aq) + H2O(b) (Eqn.2) 2H2(g) + O2(g) → 2H2O(l) (Eqn.3) a. Using Hess' Law, these equations can be rearranged to give the overall reaction of interest for this experiment (Eqn.4): Mg(s) + 1/2O2(g) → MgO(s) (Eqn.4) What must be done with Equation 1? (Reversed? Multiplied by a factor? If so, what factor? Left as is?) What must be done with Equation 2? What must be done with equation 3 ? b. In lab you will be determining the values of ΔH for the Mg and MgO reactions (Eqn.1, Eqn.2). IF one of those values of ΔH is negative and that reaction is reversed when applying Hess' Law, what sign will the value of ΔH have for that reaction? c. What is the meaning of a negative enthalpy value? Beginning Question Enter your beginning question for this experiment. Safety Considerations What are the safe

Spacecraft propelled by laser radiation from Earth has been proposed recently. To test the concept a 10 kW laser with output circular beam of 2 meters in diameter is aimed at a spacecraft having a perfectly reflective mirror in a shape of a square with a side of 1 m oriented perpendicular to the beam. The spacecraft is at a distance of 300 km from the laser. Find: [a] (2pts) Calculate the maximum electric field $E_0$ in the laser beam? [b] (2pts) What is the intensity of the electromagnetic radiation hitting the sail? [c] (2 pts) What is the radiation pressure exerted by the laser beam on the sail? [d] (2pts) What is the radiation force exerted by the laser beam on the sail?
