Question is what is difference between relative atomic mass and atomic mass unit.
We recently did a lab/demo using the NMR to observe Na ions in sodium complexes in our Inorganic Class. I understand most of the post lab questions, but there are a few that still have me stumped.
Calculate the gibbs energy , entropy and enthalphy of mixixng when 1 mol of C6H14 is mixed with 1 mol of C7H16. at 298K. assuming to be ideal.
A mixture is prepared from 15.0 l of ammonia and 15.0 l chlorine measured at the same conditions these compounds react according to the following equation 2NH3+3Cl2---> N2+6HCl When the reaction is completed what is the volume of each gas
Calculate molar concentration of a 4.50 l solution that contains 35.5 g of dissolved sodium hydrogen carbonate. Why should solute be added to water rather than water added to solute.
