What happens in the process of beta decay? a. a neutron transforms into a proton and an electron. b. a proton transforms into a neutron and an electron. c. a neutron and an electron combine to make a proton. d. a proton and an electron combine to make a neutron.

A. A neutron transforms into a proton and an electron.

Explanation:

Yes, this is what happens in β decay.

The proton stays in the nucleus and increases the atomic number by one, and the electron is ejected from the nucleus.

B is wrong. This is impossible because charge is not conserved. You can’t convert a positive particle into a negative particle.

C is wrong. Again, this is impossible because charge is not conserved.

D is wrong. Charge is conserved, but this is the process of electron capture.

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 :
