The reason for the use of stemless funnels instead of long-stem funnels to filter hot solutions through filter paper should be explained. Concept introduction: The funnel is a tube that is narrow at the bottom but wide at the top. It is used to pour liquids or power through a small opening. It is generally made up of stainless steel, aluminium, glass or plastic. The material used to make funnels is chosen in such a way that it does not react with the other substances. Following are some of the types of funnels: Filter funnels Thisle funnel Dropping funnel Buchner funnel Hirsch funnel Tullgren funnel Separatory funnel

Question

we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusion

Q5. Predict the organic product(s) for the following transformations. If no reaction will take place (or the reaction is not synthetically useful), write "N.R.". Determine what type of transition state is present for each reaction (think Hammond Postulate). I Br₂ CH3 F2, light CH3 Heat CH3 F₂ Heat Br2, light 12, light CH3 Cl2, light No
