A common industrial unit for articulating the concentration of hydrogen peroxide is to state the relative volume of oxygen gas at 0 C and 1 atm, produced per volume of hydrogen peroxide solution that decomposes.
A student wanted to dry some diacetone alcohol A and allowed it to stand over andydrous potassium carbonate for a week. At the end of the week the sample was found to contain pure acetone. Propose a mechanism for the reaction that took place.
What is the rate of consumption of O2 in a combustion reaction carried out in a 11.00 L flask if 6.30 mmol of oxygen is consumed in 25.6 s?
which of the following is NOT a vitamin that is used by cells to produce a cofactor requires by alpa-ketogluterate dehydrogenase
Because molecular bromine is a strong and toxic oxidant, excess bromine is neutralized. Addition of the aqueous sodium thiosulfate is used for that reason. Sodium thiosulfate is a good reducing agent and converts molecular bromine to sodium bromid..
