Answer:
Explanation:
Mg²⁺ is divalent , hence
Molecular weight / 2 = equivalent weight .
.25 moles = 2 x .25 equivalents = .5 equivalents .
Cl⁻ is monovalent so
molecular weight = equivalent weight
.50 mole = .50 equivalent
Total equivalent = .50 of Mg²⁺ + .50 of Cl⁻
= 1 equivalent .
Amino Acids undergo a kind of acid base reaction within a molecule. The
Amino group acts as a base and accepts proton from
Carboxylic functional group resulting in formation of
Ammonium with positive charge and a negative charge on
Carboxylate. Such molecules containing both positive and negative charges are called as
Zwittor Ions.
Phenylalanine both in Un-ionized and Ionized form is shown below,
Answer: represents oxidation.
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Example:
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
Example:
represents oxidation.
