a) Hydration of Butane with dilute H as catalyst
b) Substitution, between Cl2 and Pentane (No idea)
c) Substitution between Br2 and Hexane (Cyclohexane + bromine → 3-bromohexane + HBr)
Looks fine, if its 5 marks you're aiming to fit in into 10 lines. When writing on paper so I would remove the 'taste' part.
I would also set out mine differently.
Equation
State definition of LCP
↓T → ↑CO2(aq) etc. I wouldn't have to relate back to LCP if I did I'll just write (LCP) instead of...
Because there's a square on the bottom. Thus when you pug you half (0.5) and you square it you get 0.25. So its 4 times less than originally. Eg, Let Radius X be A therefore Radius Y is A/2 so (A/2)^2 = A^2/4
2. At that time they believed that the interferometer was accurate enough to detect...
I've been researching this week for a material was the largely developed as a result of space exploration, not simply an existing technology which is used in space. It must be produced for the purpose of space exploration and is now used in our everyday life.
Anyone got any ideas? Fucking hard...
Use Surfing Physics - Space very good text book for projectile motion but its more of an advance type of questions and its probably too late for you to buy a text book.
I know what contributions Von braun did but come anyone tell me the significance of him developing the liquid fuel with Oberth, what has the development of Saturn-V helped us nowadays, and to be sure was Jupiter-C the first 3-stage rocket.
