Explanation:
The nuclear reaction is a radioactive decay by the emission of a beta particle.
Beta emission increases the mass number of a nuclei.
A beta particle is a particle that closely resembles an electron. When a particle decays by emitting beta particles, the mass number remains the same but the atomic number increases.
Beta particle is designated as °₋₁β
²³₁₀ Ne ⇒ ²³₁₁Na + °₋₁β + energy

Answer:
May be boiling is the answer because all other options are a proper chemical changes.
Answer:
1.Ca atom has greater radius than Ca+2
2.F- ion has larger radius than F
At 50 degrees Celsius and standard pressure inter-molecular forces of attraction are strongest in a sample of ethanoic acid.
Ethanoic acid has hydrogen atom bonded with a more electronegative atom; Oxygen. As a result, the molecule possesses strong intermolecular Hydrogen Bonds. Therefore; ethanoic acid, and all other carboxyllic acids have the tendency to form dimers.
