100 mL of 0.5 M HCl is mixed with 100 mL 0.5 M NaOH in a constant pressure calorimeter (S cup= 335J K^-1). The initial temperature of the HCl and NaOH solutions are 22.5C and final temperature of the solution is 24.9C. Calculate the molar heat of neutralization assuming the specific heat of the solution is the same as for water
Problem- a.1) Muscle biopsy and enzyme assays of a carnitine-deficient individual demonstrate that medium-chain (C8-C10) fatty acids can be metabolized normall, despite the carnitine deficiency. What does this tell you about the role of carnitine ..
