Which best describes a beta particle that is emitted during nuclear decay?
a. a high-energy photon
b. a boron nucleus
c. an electron
d. a helium nucleus

I believe the correct answer from the choices listed above is option C. A  beta particle that is emitted during nuclear decay is an electron. The high energy electron emitted in this reaction is called a beta particle and is represented by 0−1e−−10e− in nuclear equations. 

Hope this answers the question. Have a nice day.

The correct answer is Option C.

Explanation:

A beta particle is released when a nucleus undergoes a beta decay process. In this process, a neutron gets converted to a proton and an electron. The electron released is known as beta particle only.

The equation that represents beta decay process is:

The charge that this particle carries is -1 and it has a mass of 0 units. It is represented as of

Hence, the correct answer is Option C.

1. single replacement

Explanation:

Single replacement can be represented by AB+C ⇄B+AC, which matches the picture

Double replacement and double displacement are the same kind of reaction and can be represented by AB+CD ⇄BD+AC

Decomposition reaction can be represented by AB ⇄A+B
