The big bang was an event of unimaginably huge power! Now; I have seen and read all kinds of theories about how it all began, I`ve seen graphs about big bang itself. One popular picture depicts the explosion radiating outwards; It leaves more questions than answers about the nature of the bang. To me; when theres` an explosion, with nothing nearby to direct the blast in one direction or another; the blast will radiate 360 degrees. Now; should`nt it be possible, knowing the direction and speed of of all the objects in the cosmos; to trace the objects backwards until the actual starting point of this astonishing event???? (just a thought)

A gaseous sample weighing 0.896 g was found to occupy a volume of 524 mL at 730 mmHg and 28C. What is the molar mass of the gas?

I know I have to use M= mRT/PV

Theres an example in my book to set it up:

=0.896g x 62,400mL-mm Hg/mol-K x 301 K / 730 mmHg x 524 ml

My question is, where did that 62,400 mL-mm come from?

(there are four choices)

1) y= ax2+bx+c

2) sin(x+y) = sinx cosy + cosx siny

3) A2 + B2 = C2

4) y = mx + b

please help!!!

3. Some of the reactions of halogens are shown below. They are all examples of redox reactions. In each case state which element is oxidised and which is reduced, and give the oxidation states before and after the reaction. It says it wants you to put the state numbers under each element etc.

a) 2AgCl = 2Ag + Cl2
b) Cl2 + 2OH- = Cl- + ClO- + H20
c) 2Fe + 3Cl2 = 2FeCl3
d) 3Br2 + 6OH- = BrO3- + 5Br- + 3H2O
e) 2Br- +2H+ + H2SO4 = Br2 + So2 + 2H2O
f) 8I- + 8H+ + H2SO4 - 4I2 + H2S + 4H20
g) 4IO3- = 3IO4- + I-
h) H2 + Cl2 = 2HCL
i) 2F2 + 2H2O = 4HF + O2

Please notice that you will have to look quite hard to see the minus signs!

Thanks for all your help, much appreciated! Please

we went to the moon or not?

There are 400,000 reasons to say we went (the number of Apollo workers over the 7 year period), and another few hundred absolute witnesses (the controllers who worked the banks of displays at Florida and Houston - how would you get a Hollywood past them for 7 years).

There were half a dozen stupid and scientifically lacking reasons given by Fox news, and half the kids in the USA believe the latter.

Those kids should be celebrating the most exciting and amazing voyages of discovery ever, and instead they are listening to the ramblings of ignorant crackpots.
