How many grams of CO2 are produced when 100.0 grams C4H10 are burned in an excess of oxygen as follows:
2C4H10 + 13O2 = 8CO2 + 10H2O
The pH after adding 10. mL of .10 M NaOH is 4.31. Calculate the total volume of .10 M NaOH that the buffered sample can absorb
The question is that Iron can be determined spectrophotometrically after reaction with a ligand that results in a highly colored complex. In one determination, iron is reduced with hydroquinone to ensure it is all in Fe2+ oxidation state.
Air is 21 mole percent oxygen, that is, 0.21 atm oxygen at 1 atm. Suppose the pH of the water is 4.54 and that the concentration of iron(II) in the water is 5.16x 10-5 M, what is the potential of the corrosion reaction under the above conditions a..
