6 0

Answer:

For mole conversion always remember 1 mole of compound = molar mass of compound.

Ex. 2 moles H20 to grams

2mol H2O x 18 g / 1mol H20

For molecules use Avogadro's number like moles multiplied to 6.022x10²³ answer will be in molecules.

Beta radiations:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation

⁴₆C → ¹⁴₇N + ⁰₋₁e

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.
