For q.16 You have a train which is moving. It has a resultant force from the engines due to the total resistive force The resistive force is divided into two types, air resistance and wheel friction. They want to know they ratio of air resistance to wheel friction of the total resistive force... -

You just need to understand these: Pressure is DIRECTLY PROPORTIONAL to Temperature p=nt Pressure is INDIRECTLY PROPORTIONAL to volume p=n/v where n is a constant from there you derive the equations :P1V1=P2V2, P1/T1 = P2/T2, P1V1/T1 = P2V2/T2 Its pretty simply if you can understand the... -

The formula for propane is CH3CH2CH3, so chlorine can replace each hydrogen atom in ch2 or each hydrogen atom from the two ch3 groups. so the chances of chlorine replacing two hydrogens in ch2 is 2 (2 hydrogens) and 6 for the two ch3 groups (6 hydrogens) 6/2 = 3/1 -

OH, I didnt know about this, thanks for informing me about it!!:D:D -

BTW BTW there is an easier way. USE this : [P1V1]/T1 = [P2V2]/T2 and put in the values you put in. Much quicker and less hassle! hope this helped you:) -
