A 1.5-kg specimen of a 90 wt% Pb-10 wt% Sn alloy is heated to 250°C;at this temperature it is entirely an alpha -phase solid solution. The alloy is to be melted to the extent that 50% of the specimen is liquid, the remainder being the alpha phase. This may be accomplished either by heating the alloy or changing its composition while holding the temperature constant. To what temperature must the specimen be heated? Ⓒa. 100 deg C O b. 265 deg C O O d. 500 deg C c. 294 deg C

Mganga is doing a routine analysis in a copper plating factory. He is regularly making up solutions of verypure CuSO4.5H2O. He suspect that a batch of a reagent used to make up a stock solution of CuSO4.5H2Ois impure and it may contains some CuCl2. He asked you to determine the percentage impurity as follows:Dissolve1.500g of a mixture and make up to 1.00L mark.150mL of this solution was treated with 20.00mLof 0.100M AgNO3 to remove 98.6% of chloride as AgCl precipitate.

physical chemistry Roughly, what is the error introduced by the solution of some of the CO2 in the water in the bomb? The solubility of CO2 is about 0.0015 g/mL at 25°C and 1 atm CO2 pressure. The heat of solution of CO2 in a dilute aqueous solution is roughly -19.4 kJ/mol. Assume that the final CO2 pressure is 2 atm and that Henry's Law applies.
A soil sample taken from a hill reveals that soil solution in the top 30 cm of soil contains 900 micromoles Ca/L. Imagine that the grass growing on this hill has a water use efficiency of 400 g H20/g dry matter. Calcium is considered to be sufficient when between 1-2% of the dry matter. Calculate the calcium content in the soil's dry matter and determine if the level is sufficient.

Iron oxides can be smelted in a blast furnace by reacting with Cco), which serves as the reducing agent. To supply the needed reducing agent, Ce) is added to the blast furnace and is converted to CO(g) through a sequence of two reactions: Reaction I: C(e) + O2(0) – CO2(9) Reaction II: C(s) + CO2(9) - 2 CO(g) The standard enthalpies of formation at 298 K for CO29) and COg) are -394 kJ/mol and -111 kJ/mol, respectively. Which of the following statements is TRUE? O The overall reaction has an increasing slope when plotted in an Ellingham diagram. O The overall reaction is spontaneous only at high temperatures. O Reactions I and Il are both an exothermic process. Reaction I is exothermic, whereas Reaction II is endothermic.

A steel model was cooled down from 1000°C. a. Find the composition of the steel, if, at 800°C the model contains austenite and ferrite at a ratio of 1:3. b. Calculate the relative amounts of cementite and ferrite at room temperature (X-95.6%).
Aluminum is the most abundant metal in the earth’s crust. It is also a common household utensilmetal. The extraction of Aluminum from its ore is expensive because the metallurgy uses a veryhigh amount of electricity. The extraction of Aluminum metal takes place in a number of steps,which may be summarized below.Step 1: Washing and mechanical processes employed to the ore to remove basic impurities.Step 2: Conversion of Aluminum ore (Bauxite) to powdered Alumina (Al2O3) by reaction withconcentrated NaOH solution.Step 3: Dissolving Alumina in molten Cryolite(Na3AlF6)Step 4: Electrolytic refining of the solution at step 2. (Diagram below) to form pure Aluminummetal.Step 5: Collecting pure molten Aluminum at the cathode, which change later to solid Aluminummetal.As you observed, many changes are taking place in different steps for the above extractionprocess. Classify them as physical or chemical change and explain why?a) Step 1 __________________________________________b) Step 2…
