Question: The periodic table of elements has predictable trends, one trend is in atomic structure. Review the elements in the periodic table.
Describe the trend in atomic number. Begin with hydrogen and move through the table. How is this trend evidenced in the structure of
the atoms of each element?

What reaction is taking place? 02 + c3h8 = h20 + co2

Achemist has dissolved a certain substance in water. the chemist knows that more of the substance could be dissolved into the water before it stops dissolving. therefore

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.
