It's not about the shape of the headphones, it's about the sound. It seems (and i may be wrong here) that even if it's a song I haven't heard, it just sounds a bit odd if i'm listening to the left speaker from theright and visa versa

25.00cm^2 of a solution containing iron (II) and iron (III) sulphate required 20.50cm^2 of 0.02 mol dm^-3 pottasium pemanganate for oxidation. After complete reduction by zinc amalgum, 25.00cm^3 of the solution required 34.80cm^3 of the same pemanganate solution. Calculate the concentration of iron (II) and iron (III) ions present in the given solution. [RAM; H:1 ; O:16 ; Fe : 56].

I would appreciate an answer with a full explaination. I am totally lost with this. Thank you in advance.

It is known from the 2nd Law of Thermodynamics that when a spontaneous reaction occurs, there is an increase in the entropy of the universe. Therefore, the change in entropy of the universe is non-negative at any one time.

Yes or No

_______NF3
_______SiH4
_______N20


My guess:
I know that permanent dipoles occur when two atoms in molecules have differing eletronegativity, as when one atom attracts electrons more than another becoming more negative, the other atoms becomes more positive.

? yes------->NF3
?yes--------->SiH4
?yes--------->N20

Cambridge Soft's ChemFinder is disabled so I cannot get a close enough look at these. I just took some guesses. Please double check.

Thanks!

when I was about 12 and fishing on a pond some much bigger boys than me would bring sodium valves with a hole drilled in the valve and throw them into the pond, minutes later they exploded and fish floated to the top and they swam out to get them, now this was 45 years ago as memory serves me.????
