write the nuclear fusion reaction for nitrogen- 14 fusing with Helium- 4.
Two reactors are connected by a small valve (whose volume can be ignored). The larger one has a volume of 3.00 L and contains F2 at a pressure of 3.000 bar. The small one has a volume of 2.00 L and contains Cl2 at a pressure of 2.000 bar. The whole system is kept at 328 °C.
When the valve between the chambers is opened, the following reaction occurs:
3 F2(g) + Cl2(g) → 2 ClF3(g)
Calculate the mole fractions and partial pressures of all species present after reaction. [Cl2: 14.3% and 0.200 bar; ClF3: 85.7% and 1.20 bar
Scientists can determine the age of ancient objects by the method of radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to radioactive isotope of carbon, 14C, with
a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon and the
amount of ¹4C begins to decrease through radioactive decay. Therefore the level of radioactivity must also decay exponentially. A parchment fragment was discovered that had about 74% as much 14C
radioactivity as does plant material on earth today. Estimate the age of the parchment. (Round your answer to the nearest whole number.)
