A chemistry student is experimentally determining the boiling point of bromine. The experimental melting points are listed
below from a toe. Which one should he discard so that he can
say his data is precise?
a 59.1°C
b 59.0 °C
C 58.8 °C
d 58.5 °C
e 56.3 °C

How many moles of air are there in a human lung with a volume of 2.4 l at stp? explain your answer

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
