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.

h let me think

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
