    OMG! Physics p22!!!

    Dude MeV means mega electron volts. You know Voltage or Pd is work done per charge. and since work done is energy, if you multiply Voltage by e the charge you get Energy. And anyways the question said that 1.1MeV is the kinetic energy itself.

    The thing with that Cambridge scholarship is that it's only awarded to those who are pretty much.... well lets face it --EXTRAORDINARY.

    confirm salts chem34

    Uncertainaties are usually the half of the least value. yep the common ion was NH4+, Fe2+ was the other cation. with sulfate being present in FA 7. The gradient was 2.3 and the final answer was 24.9 kJ/mol. FA 9 was ketone and FA 10 and 11 were alcohols. I wrote systematic error. Dont know if...
