Balance the following equations using the smallest integer coefficients. a. Ca3P2(s)+ H2O → Ca(OH)2(aq)+ PH3(g) b. Al(NO3)3(aq) + Na2CO3(aq) → Al2(CO3)3(s) + NaNO3(aq)

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.

How are the terms group and period used on the periodic table

Now look at the segment of the graph between the two data points marked with black squares. describe how the boiling point and melting point plots behave between these points. be as specific as possible.
