When a 50mL aliquots of this solution was titrated, 11.35mL of 0.10359M NaOH solution was required to reach the end point. Calculate the percentage of Fe2(SO4) in the unknown solid.
A steel is heated until 85% austenite, with a carbon content of 1.05%, forms. Estimate the temperature and the overall carbon content of the steel.
Octane ratings are assigned to gasoline mixtures based on their ability to prevent knocking relative to isooctane. Estimate the energy released during the combustion of 1.00 mol of pure isooctane.
Five potential structures belonging to point groups Oh,D3h,D6h,D2h and D3d. Sketch geometries that are consistent with the possible point groups?
We did an experiment to isolate acetylsalicyclic acid from aspirin using methanol. We crushed the aspirin tablet before the extraction began. Why were we instructed to crush the aspirin tablet before proceeding
In Complex III, electrons are transferred between ubiquinone and cytochrome c. Standard reduction potentials are, write a balanced equation for this reaction and calculate the overall cell potential and free energy change.
Calculate ?rH° for the reaction 2C(s) + 3 H2(g) + ½ O2(g) ? C2H5OH(l) given the information below. C(s) + O2(g) ? CO2(g) ?rH° = -393.5 kJ/mol-rxn 2 H2(g) + O2(g) ? 2 H2O(l) ?rH° = -571.6 kJ/mol-rxn C2H5OH(l) + 3 O2(g) ? 2 CO2(g) + 3 H2O(l) ?rH° = ..
