A mixture of 8-hydroxyquinoline(Q) complexes of aluminum and magnesium weighed 1.856 g. When ignited in a furance open to air, the mxiture decomposed, leaving a residue of Al2O3 and MgO weighing 0.216 g. Find the weight percent of MgQ2 in the original mixture. AIQ3 + MgQ2 + heat --> Al2O3 + MgO Molar mass( g/mol): AIQ3 = 459.441, MgQ2 = 312.611, Al2O3 = 101.961, MgO = 40.304 Write answer to 1 decimal place. No % sign in answer.

Solid residue weighing 7.158 g from an aluminum refining process was dissolved in acid to give Al3+ in solution. The solution was treated with 8-hydroxyquinoline to precipitate (8-hydroxyquinoline)3Al (FM 462.462 g/mol), which was ignited to give Al2O3 (FM 101.961 g/mol) weighing 1.178 g. Find the weight percent of Al (FM 26.982 g/mol) in the original mixture.

The piperazine content of an impure commercial material can be determined by precipitating and weighing the diacetate: :NH HN: + 2CH CO,H → HẠN Piperazine FM 86.136 → HẠN NH,(CH,CO,), Acetic acid FM 60.052 Piperazine diacetate FM 206.240 In one experiment. 0.3126 g of sample was dissolved in 25 mL of acetone, and 1 mL of acetic acid was added. After 5 min, the precipitate was filtered, washed with acetone, dried at 1108°C, and found to weight 0.7121 g. Find the wt% of piperazine in the sample.

Chromel is an alloy composed of nickel, iron, and chromium. A 0.6392-g sample was dissolved and diluted to 250.0 mL. When a 50.00-mL aliquot of 0.05173 M EDTA was mixed with an equal volume of the diluted sample, all three ions were chelated, and a 5.15-mL back-titration with 0.06139 M copper(II) was required. The chromium in a second 50.0-mL aliquot was masked through the addition of hexamethylenetetramine; titration of the Fe and Ni required 34.27 mL of 0.05173 M EDTA. Iron and chromium were masked with pyrophosphate in a third 50.0-mL aliquot, and the nickel was titrated with 24.31 mL of the EDTA solution. Calculate the percentages of nickel, chromium, and iron in the alloy. Percentage of nickel = % Percentage of iron = Percentage of chromium = % 10
