Which feature of nuclear fission reactions allows these reactions to take place in a chain reaction?

a) thermal energy is released and heats up the reactants.
b) more smaller atoms form that can undergo fission.
c) a larger atom is formed, which can then be split.
d) neutrons start the reaction and are released during it.

Hi!

The correct answer is D) Neutrons start the reaction and are released during it.

Hope this helps!

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
