Red blood cells are red because they contain Haemoglobin
alpha decay is an emission of ₂⁴He
nucleus. If an element undergoes an alpha decay, the mass of the daughter
nucleus formed is reduced by 4 compared to mass of parent atom and atomic
number is reduced by 2 compared to atomic number of parent atom.
Let's assume that the parent atom is X, atomic number is z and mass number is A. Then the formed daughter nucleus, Y should have atomic number as z-2 and mass number as A-4.
The equation is
(z) (A)X → ₂⁴α + (z-2)(A-4)Y
Example:
₉₄²³⁹Pu → ₂⁴α + ₉₂<span>²³⁵U</span>
Answer:
t-butyl cation
Explanation:
Generally a dehydration reaction occurs when an organic compound loses water molecules to form alkenes. However, in an acid-catalyzed dehydration, the dehydration reaction occurs in the presence of an acidic compound which acts as a catalyst. Therefore, for this specific case, the hydride will migrate and a t-butyl cation will be formed. This is because it is more stable due to the presence of three electron releasing alkyl groups which can stabilize a positive charge compared with the secondary cation formed when the methyl group migrates.
Iron (Fe) has 26 protons.
