Which variable determines the electron energy in the hydrogen atom according to bohr’s model

Answer is "n", Principle Quantum Number.

Explanation: Bohr's model of Hydrogen atom is based on the quantum mechanics where an assumption was taken that an electron travels in specific orbits around the nucleus.

Energy of the electron in a shell is be given as:

Where, = Rydberg's constant

n = Integer called as principle quantum number and it corresponds to the different allowed orbits from an electron.

From the equation above we can easily tell that its the Principle Q. No. which determines the electron energy in the hydrogen atom.

whats the meaning of /

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 :
