a sample of nitrogen occupies a volume 300 Ml at 30 degrees celcius and 700 mm Hg of pressure. what will be its volume at STP.
K2Cr2O7 was used to titrate a sample known to contain a mixture of sodium sulfate (Na2C2O4) and sodium oxalate (K2C2O4). The dichromate does not react with sodium sulfate.
The first mechanism includes sodium acetate to yield beta-penta-acetate and the first mechanism includes zinc chloride (Lewis acid) to form an oxonium ion to yield the alpha-penta-acetate product. Any help to draw out the mechs would be much appre..
