    complete combustion of a compound per mol is defined as the enthalpy of combustion. We can deduce this as the enthalpy of combustion of methanol (CH3OH) is -726 KJ/mol, and the enthalpy of combustion of ethanol (C2H5OH) is -1367 KJ/mol. As we can see the absolute value of the enthalpy of combustion of ethanol (i.e. 1367 KJ/mol) is much greater than the absolute value of the enthalpy of combustion of methanol (i.e. 726…

    Raju Chandra et al; A reliable and reproducible reversed-phase high performance liquid chromatography (RP-HPLC) was developed for the quantitative determination of quetiapine fumarate from marketed bulk tablets. The active ingredient of quetiapine fumarate separation achieved with C18 column using the methanol water mobile phase in the ratio of 30:70 (v/v). The active ingredient of the drug content quantify with UV detector at 359 nm. The retention time of quetiapine fumarate is 5.27 min. A good…
