Titanium occurs in the magnetic mineral ilmenite (FeTiO3), which is often found mixed up with sand. The ilmenite can be separated from the sand with magnets. The titanium can then be extracted from the ilmenite by the following set of reactions: FeTiO3 (s)+TiCl₂, (g) (8)+3Cl₂(g)+3C(s)→3CO(g)+FeCl₂ TiCl4 (9)+2Mg(s)→2MgCl₂(1)+Ti(s) Suppose that an ilmenite-sand mixture contains 20.2 % ilmenite by mass and that the first reaction is carried out with a 91.3 % yield. Part A If the second reaction is carried out with an 87.0 % yield, what mass of titanium can be obtained from 1.00 kg of the ilmenite-sand mixture?

The thermite reaction is written below. Show that the heat released in this reaction is sufficient for the iron to be produced as molten metal. Find the enthalpy of formation of the overall reaction. Al(s) + Where: Al ΔΗ°F= 0 Al2O3 AHF -2076 Fe AHF 0 Fe2O3 AHF -745 Fe₂O3(s)- → Al₂O3(s) + Fe(1)

A sample of steel was dissolved and the manganese present was converted to MnO4– (aq). Water was then added to give a final solution volume of 100.00 mL. A sample of this solution was examined and was found to have an absorbance at 525 nm of 0.560 (pathlength = exactly 1 cm). What is the concentration of MnO4– in the solution? (The molar absorptivity is 3.62 × 103 L/(mol cm).)

Sodium hydrogen sulfate is used as a cleaning agent and as a flux (a substance that promotes the fusing of metals and prevents the formation of oxides). One of the ways in which sodium hydrogen sulfate is manufactured is by reacting sodium dichromate, Na2Cr2O7, with sulfuric acid. This process also forms water and chromium(VI) oxide, CrO3. Write a balanced equation for this reaction. (You do not need to include states.) How many kilograms of sodium dichromate, Na2Cr2O7, are necessary to produce 130.4 kg of sodium hydrogen sulfate? How many kilograms of chromium(VI) oxide are formed when 130.4 kg of sodium hydrogen sulfate is made? What is the minimum volume of 18.0 M H2SO4 solution necessary to react with 874.0 kg of sodium dichromate? What is the maximum mass of sodium hydrogen sulfate, NaHSO4, that can be formed from the reaction of 874.0 kg of sodium dichromate with 400.0 L of 18.0 M H2SO4?

What is the struture of this product and what type of reaction is this?

Fine particles of metallic iron can be injected underground to remediate pollution of underground aquifers by the industrial solvent trichloroethane. In one experiment, 2400L of an aqueous emulsion containing ~480 kg of Fe(0) consumed  17.0 kg of trichloroethane in 5 months.  Write a balanced reaction using H2O and H+ to complete the balancing.  What percentage of injected iron was used by this reaction in 5 months? Fe + C2HCl3 ---> Fe2+ + C2H4 + Cl-

Calculate the equilibrium constant for the reaction:   NO2 (g)  +  NO (g)     N2O (g)  +  O2  (g)

The Fe2+Fe2+ (55.84555.845 g/mol) content of a 2.2472.247 g steel sample dissolved in 50.0050.00 mL of an acidic solution was determined by tiration with a standardized 0.1200.120 M potassium permanganate (KMnO4KMnO4, 158.034158.034 g/mol) solution. The titration required 29.2929.29 mL to reach the end point. What is the concentration of iron in the steel sample? Express your answer as grams of FeFe per gram of steel.   MnO−4+8H++5Fe2+↽−−⇀Mn2++5Fe3++4H2OMnO4−+8H++5Fe2+↽−−⇀Mn2++5Fe3++4H2O concentration: g Fe/g steel (please type answer not write by hend)
