Write the chemical equation for the standard molar enthalpy of formation of butanol, C4H10O.
student is trying to determine the molar enthalpy change for a neutralization reaction and obtained the following temperature data initial temperature of acid 21.48°C: initial Temperature of base = 21.53°C final temperature 18.21°C. Is their data correct? In one sentence explain why or why not
The enthalpy change for a chemical reaction is the sum of the
energy consumed in breaking bonds and the energy released during
bond formation. One way to determine the overall energy change for
a chemical reaction is to apply Hess’s law to add together a group
of reactions which can be arranged such that the chemical
equations, when combined, give the overall equation we are trying
to characterize.
