Hess's Law

I was given the duty of determining whether or not the workers legend of being open firet is supported by scientific evidence. By using calorimetry and Hesss Law, the validity of the workers claim plenty be run aground. The scientists try was compared and evaluated with a similar one that was completed with less plaza for safety reasons. 5 grams of NaOH was mixed with 41 ml of HCL. With this reaction, the H can be found by using the par q=mc T. It was found that q=70759.04. From this result, H can be found by dividing q by the number of moles of NaOH. The results showed that H=70246.29. According to Hesss Law, it doesnt issuance what pathway is used to make a substance because the H will always be the same. By comparing the workers results with our own, the resultant role can be found. The equating used is 70759.04=(505)(4.18)(Tf-25). With this equation it was indomitable that the final temperature of the scientists mixture was 60 degrees Celsius. Thus, the mixture was hot ample to shatter glass and burn the worker.
