Answer:
⁴⁰₂₀Ca + ⁰₋₁e
Explanation:
Beta decay:
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.
Properties of beta radiations:
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
⁴⁰₁₉K → ⁴⁰₂₀Ca + ⁰₋₁e
The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.
I only know #8 and the raindrop would increase speed due to gravity.
Answer:
Sulfur, kill me if I'm wrong
Answer: The correct answer to the question is option A. HBr + NaOH –> NaBr + H₂O
Explanation: An acid-base reaction is otherwise known as neutralization reaction. This is a reaction in which an acid reacts with a base to produce salt and water only.
