Se mezclan 20 ml de una solución al 5% m/v, 50 ml de otra solución al 12% m/v y todo esto con 50ml de agua. Calcule el %m/v de la nueva solución.​

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

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.
