10.11/ A 1.5-kg specimen of a 90 wt% Pb-10 wt% Sn alloy is heated to 250°C (480°F), at which temperature it is entirely an a-phase solid solution . The alloy is to be melted to the extent that 50% of the speci- men is liquid, the remainder being the a phase. This may be accomplished either by heating the alloy or changing its composi- tion while holding the temperature con- stant. (a) To what temperature must the speci- men be heated?

Modern commercial airliners are largely made of aluminum, a light and strong metal. But the fact that aluminum is cheap enough that airplanes can be made out of it is a bit of historical luck. Before the discovery of the Hall-Héroult process in 1886 , aluminum was as rare and expensive as gold. What would happen if airplanes had to be made of steel? The fuselage of the Airbus A380, which can carry 575 passengers, is approximately a hollow aluminum cylinder without ends, 72.0m long, 8.4m wide, and 2.5mm thick (see sketch at right). The fuselage of an airplane Suppose this fuselage was made of steel (density 7.87/gcm3 ) instead of aluminum (density 2.70/gcm3 ), and let's say the average passenger has a mass of 83kg . We'll also assume the engines can't lift any greater mass than they already do. Calculate the number of passengers that the Airbus A380 could carry if its fuselage was made of steel.
Referring to the Al-Si Eutectic diagram discussed on the Phase Diagrams-Lever Rule handout, calculate the mass fraction of the phase, silicon, given a sample with 51.7 wt% aluminum at 576.99 ˚C.
Though many MNCs espouse and follow rigid codes of social responsibility in their home countries they are often not as diligent with respect to ‘host’ or overseas countries. In 1984 the Bhopal disaster in Madhya Pradesh, India killed 3,787 and impacted a further 558,125 people. The corporation in question was Union Carbide, a majority USA owned company. Indian courts convicted the Chairman and other senior executives of “…causing death by negligence”. Why do you believe that Union Carbide had a less stringent policy in India with respect to negligence than they did in the USA?

A student is given a sample of a pink manganese (II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 26.742g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool and finds it has a lower mass; the crucible, cover and contents then weigh 25.598g. In the process the sample was converted to off-white anhydrous MnCl2. a. What was the mass of the hydrate sample? _ghydrate b. What is the mass of the anhydrous MnCl2? _gMnCl2 c. How much water was driven off? _gH2O d.
