Balanced chemical equation for the hydrogenation of glyceryl trilinolenate:
C₅₇H₉₂O₆ + 9H₂ → C₅₇H₁₁₀O₆.
Linolenic acid (octadecatrienoic acids ) is a type of fatty acid. It has 18 carbon atoms chain and three double bonds. So trilinolenate has nine double bonds.
Trilinolenate is the form of triglyceride esters of linolenic acid.
Hydrogenation is addition of hydrogen atoms at both sides of a double bond.
Answer:
It s a pure substance.
Explanation:
Can only be separated into its different elements by chemical means because it is connected by a chemical bond.
Answer: Iron gains electrons mean It is reduced
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.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Thus iron gains electrons mean It is reduced
