(9.42x10^24)/(6.02x10^23)=15.6478 mol methanol
15.6478mol(32.04g/1 mol)=501.3568g methanol
It speeds up chemical reactions
The RDA for iodine in adults is 150 micrograms
To meet this, one must consume:
150 / 0.7645
= 196.2 micrograms of potassium iodide per day.
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.
