Alcohols are compound that has one or more hydrogen atoms in an alkane which has been replaced by an –OH group (Chem Guide, 2003).The general chemical formula for alcohols is CnH2n+1OH (BBC, 2014).Alcohols are any of a class of organic compounds characterized by one or more hydroxyl (−OH) groups attached to a carbon atom of an …show more content…
This law is a manifestation that enthalpy is a state function. (UCDAVIS Chem Wiki 2015). The definition of Hess’s Law is that the heat of any ∆H○f for a specific reaction is equals to the sum the heats of reaction for any set of reactions which in sum are equivalent to the overall reaction. (UCDAVIS Chem Wiki 2015) Hess’s Law is mainly due to enthalpy being a state of function, which can calculate the overall change in enthalpy by adding up the changes for each step of the way until the product is made. All the steps have to continue at the exact same temperature and the equations for the single steps must balance out. An example of using Hess’s Law is shown below; (Chem Team,
