What is the charge of a beta particle?
0
1–
2+
4+

Option (b) is the correct answer.

Explanation:

A beta particle is a particle with a negatively charged electron. Symbol of a beta particle is .

An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.  

Symbol of an alpha particle is .

A gamma particle is basically a photon of electromagnetic radiation with a short wavelength.

Symbol of a gamma particle is .

Therefore, we can conclude that the charge of a beta particle is 1-.

the answer is 0.8m.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
