A reaction between a solution sodium carbonate is mixed with a solution of calcium nitrate to cause a precipitation reaction. If 276.3 mL of 0.723 mol/L sodium carbonate is added to 834.7 mL of 1.260 mol/L calcium nitrate, what is the mass (in g) of precipitate that forms? Provide your answer to two decimals.

This graph gives information on changes in sea ice extent in the arctic ocean over a 30-year span. the overall trend shows in the ice extent. to address the trend, scientists need to ask themselves, one direct consequence of the trend is that

At 450 mm hg a gas has a volume of 760 l, what is its volume at standard pressure

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.
