Calculate the Q-Value for the fusion reaction 1H + 11B ---> 34He. Enter your answer in MeV to 1 decimal Place .
In the Gizmo Activity B, you were given an example of a volume of gas (remember, it is pretty tough to weigh a mass of a gas....try capturing, for example, 10.0g "air" in your hands). Rather you were told that the gas was at STP. What this means is that it has a molar volume of 22.4L/mole. In the Gizmos, you did some problems in Activity B using this balanced equation. 3C02 What volume of CO2 can be produced if 72.25 g Fe is also produced? Fe2O3 + 3C0 yields 2Fe + Get your starting place (given unit) and ending place (answer unit) then determine the conversions necessary to go from one place to the next with all of your units cancelling. Answer to 2 sig figs and your unit will be L CO2
Naturally occurring uranium contains about 0.7% of the fissionable isotope 235U, with almost all the rest 238U. Since gaseous 235UF6 diffuses about 0.4% faster than 235UF6 , diffusion produces a mixture that is slightly enriched in 235UF6 . Multiple diffusion steps – hundreds are needed – can then produce the necessary 235U concentration for use in reactors or bombs. A sample of 235UF6 gas in a 15,000 L cylinder exerts a pressure of 167 kPa. The root-mean-square speed of the 235UF6 molecules is 159 m/s. What is the temperature of the sample of 235UF6 gas? _______K

What type of nuclear reaction is creating energy in this Nuclear Power Plant? Nuclear fusion, where 2 lighter atoms are combined into one under extreme high pressure releasing large amounts of light, heat and energy. Nuclear fission, where one heavier atom is split in half by a neutron, starting a chain reaction of splitting large atoms and releasing energy. O C. Alpha decay, where the nucleus shoots off a particle as large as a helium atom O D. Gamma Ray decay, where the nucleus shoots off a photon
