kruti q7 find the number of moles of Helium using PV=nRT Take temperature to be 273 (or nay random temp since it doesnt matter) Moles of helium= n= PV/RT = 0.0264 Moles of neon is also = 0.0264 now add the moles and the volumes and use in the equation P=nRT/V to get pressue of 8kPa -

I got how the correct ans is C 2. HCO2H and HOCH2CH2OH 2 is correct if we use two of HCO2H to react with HOCH2CH2OH. we will get ester HCO2CH2CH2CO2H with the molecular formula C4H6O4 3. HO2CCO2H and CH3OH 3 is corret if we react two of CH3OH with one of HO2CCO2H we will get ester with the... -

q 39 74.00g of butan-2-ol → 44.64 g of butanone Moles of butan -2 -ol =1 moles of butanone= Mass/mr =44.64/72= 0.62 now in theory 1 mole of butan 2 ol produces 1 mole of butanone. but we got 0.62 moles of butanone hence 62 percent yield Use the same method for the rest of the reactions and... -

q26 the ans is B since the aldehyde ethanal gets oxidised by ammonical silver nitrate in Tollen's, while the silver ions, Ag+, gets reduced to silver metal, Ag, hence a silver mirror forms. The ans cannot be D since there is no reaction of a ketone with Fehling's solution. q27 strobilurn is... -
