atar 99.10 happy one question: how do u know your state ranks?

Well. read throught textbooks. Basically, we use a reflux appratus to produce esters. Becase the product (ester) and the reactant (alcohol) are volatile then they would escape as they turn into vapours during heating. Then the vapour would be cooled and condensed to liquid and drop back to...

i think it is not a voltmeter but actually a galvanometer (a ampermeter) which measures the current

not so hard... case 1, moles of Al = 10/27 = 0.37 moles 2Al + 3H2SO4 --> Al2(SO4)3 + 3H2 0.37 3/2*0.37 1/2*0.37 3/2*0.37 moles 0.37 0.55 0.185 0.55 moles mass of Al2(SO4)3 = 0.185 * (27*2+ (32+16*4)*3) = 0.185 * 342 =...

A and B complex or real ?

2. Catalysts are required to decrease the required temperature. Eg thermal cracking with no catalysts involved requires 700-1000 C while the other one is about 500 3.yes 5. cause different conditions create different products for example, thermal cracking (700-1000C) : C11H24 -> 4C2H4 + C3H6 +...

F = m*a = GmM/r^2 Hence a = GM/(r^2) r = sqr(GM/a)

Sydney Opera House, i did it last year

From A to B, two railway stations, the line runs south west. Two spires, 3km a part are both N-W of A. From B, the bearings of the spires are N 7.5degree E and N 37.5 E. Shows that AB = 6 sin52.5 cos7.5. Find AB I could not draw the diagram :(

use the Kepler's equation to calculate the period

i am looking for a topic for speaking exam. Any idea ? I'm dying :( half yearly is coming

complex no graphs and just start conics Is it slow ??

man, everything is in jac phy book. Open the book and check. They got this prac

Re: outline the essential problem with light, the aether and the principle of relativ if the aether existed then light made from different objects traveling in different directions in the aether would have different velocites relate to the aether, as a result, the observer could measure and...

Thanks for advice I'll try my best :)
