HgO+CI2--> HgCI+O2 balancing equations

The drawing represents the movement of particles in a substance. what changes of state can this substance undergo

What is the mass of 4 molecules of co2

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.
