At one time, a common means of forming small quantities of oxygen gas in the laboratory was to heat KCIO3:
2 KCIO3(3) -----> 2 KCI(s) + 3 O2(g) ?H= -89.4 kj
For this reaction, calculate ?H for the formation of (a) 1.36 mol of O2 and (b) 10.4 g of KCI. (c) The decomposition of KCIO3 proceeds spontaneously when it is heated. Do you think that the reverse reaction, the formation of KCIO3 from KCI and O2, is likely to be feasible under ordinary conditions?
Phosphorus-32 has a half-life of 14.0days . Starting with 4.00 g of 32p , how many grams will remain after 42.0 days?
Using stock titrant concentration of 0.1000mol/L NaOH find NaOH concentration 1:25 dilution 10ml pipetted in 250 ml volumetric flask
What was the theoretical yield of 1-octanol under these conditions? Nancy was surprised to find that her gas chromatogram of the product mixture contained more residual 1-octene and more trialkylborane than was observed by the other students in he..
