Hess' Law

A detailed Summary of Hess' Law

Hess' Law:Work to be done:Find enthalpy change by measuring temperature change of a reaction.

The temperature of 200ml water that I poured into the isolator was 23.0°C. To that I added 1.97g solid NaOH and let the reaction take place. After a while I measured the temperature to 24.9°C a rT = 1.9°C. The number of mole NaOH is 1.97 / 40 = 0.049 mol.

Some common words found in the essay are:
Lab Reaction, HCl NaCl, Hess' Law, Hess' LawWork, Isolator NaOH, acetic acid, enthalpy change, mole naoh, rt =, / 40 =, nacl + h2o, + hcl nacl, hcl nacl +, naoh temperature, naoh reaction, hcl nacl, solid naoh, nacl +, + h2o,
