Which describes the molecule below?

a. a lipid with three unsaturated fatty acids.
b. a lipid with two unsaturated fatty acids and one saturated fatty acid.
c. a lipid with two saturated fatty acids and one unsaturated fatty acid.
d. a lipid with three saturated fatty acids

A. A lipid with three unsaturated fatty acids.

Explanation:

The molecule above is a lipid, which is a triglyceride, that contains a glycerol backbone and three fatty acids.Unsaturated fatty acids are those fatty acids with either a double bond or triple bond in its structure. A fatty acid may be mono unsaturated or polysaturated where the double bond or the triple bond may occur more than once in its structure.In this case, the lipid has three unsaturated fatty acids, since all have one double bond in their structures.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
