Considering the given equation as 4FeS2 + 11O2 ----> 2Fe2O3 + 8SO2 it is observed that A production error leads to the S2- being placed in a vessel 750 litres with insufficient O. initially it is noted that The partial pressure of Oxygen=0.44atm , total pressure =1.05atm with the balance Nitrogen. This process of reaction runs until eighty five of the Oxygen is used and the vessel get cooled to its starting or initial temperature. Determine the partial pressure and total pressure of each gas in the vessel.

Illustrate the structures of the 6 bromoalkenes (with the molecular formula C5H9Br ) that have a branched C chain, and that show neither chirality nor E,Z isomerism.
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
A container (8.65-L ) holds two gases mixture at 31 °C. The partial pressures of gas X and gas Y, respectively, are 0.206 atm and 0.867 atm. If 0.200 mol a third gas is added with no change in temperature or volume determine the total pressure be..
