Oleic acid belongs to class of alkene and in alkenes, addition of 
across 
that is carbon carbon double bond results in the formation of alkane as a product in the presence of specific catalyst such as nickel, palladium and platinum. The reaction is said to be hydrogenation reaction.
Oleic acid (
) consist of 17 carbon atoms attached to 33 hydrogen atoms with one double bond between two carbon atoms and one carboxylic group i.e.(
). When oleic acid is hydrogenated or reacts with hydrogen in the presence of catalyst, then the carbon carbon double breaks by the addition and alkane product i.e. stearic acid (
) is formed.
The chemical reaction is shown in the image.
Think, first, about the type of molecule or formula unit you have (covalent or ionic). In this case, it is a covalent molecule. You start with the carbon. You could say monocarbon, but if it is just said to be carbon it is assumed to be one. Then you take the prefix for 4 and tack it on to the beginning of the chlorine. For this, the name is carbon tetrachloride.
La energía de ionización o potencial de ionización, es la energía necesaria para extraer un electrón de un átomo neutro. Por ejemplo, cuando un átomo de cloro neutro en forma gaseosa recoge un electrón para formar un ion Cl-, libera una energía de 349 kJ/mol o 3,6 eV/átomo.

Answer:
-145.2kJ
Explanation:
Enthalpy is an extensive property as its value depends on the amount of substance present in the system.
If the enthalpy for one mole of methanol = -726 kJ/mol;
The Enthalpy for 0.2 mol is given as;
Enthalpy = 0.200 * 726
Enthalpy = -145.2kJ
It would take -145.2kJ for 0.200 mol of methanol to undego the combustion reaction.
