I'm not sure if its the conversion I did and. For a particular reaction at 135.5 C, delta G= -284.29 kJ/mol, and delta S =886.28 J/ (mol x K). Calculate delta G for this reaction at 22.7 C. I used dG= dH - T x dS formula and rearranged it to get dH..when I got dH I use it to plug in the same formula to get dG with the different temperature given.
Calculate the empirical formula and the molecular formula of the hydrocarbon, A. In an experiment, 1.000 g of a hydrocarbon, A, was burned completely in oxygen to produce 3.143 g of carbon dioxide and 1.284 g of water. In a different experiment, the molar mass of the hydrocarbon, A, was found to be 84.0 g mol -1. There are 2 steps to solve this ...
