A mixture of oxygen, carbon dioxide, and nitrogen, has a total pressure of 0.97atm. What is the partial
pressure of oxygen if the partial pressure of carbon dioxide is 0.70 atm and the partial pressure of
nitrogen is 0.12 atm? (report your with two significant digits).

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

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.

Chromosome 17 is made of over million base pairs.
