A 5.20 g sample of trans-1,2-diethylcyclopropane (formula C7H14), is mixed with 35.67 atm of O2 in a 7.38×10-1 L combustion chamber at 204.18 °C. The combustion reaction to CO2 and H2O is initiated and the vessel is cooled back to 204.18 °C. Report all answers to two decimal places in standard notation (i.e. 1.23 atm). 1. What is PH2O (in atm) in the combustion chamber assuming the reaction goes to completion? Assume all water is water vapour and that the...

Below are isomers of 1,2-di(2-methylpropyl)cyclohexane in conformational structures. Two are cis and two trans. Indicate which is the more stable conformation for the cis and which for the trans, and indicate which of all the conformations is the most stable. If both conformations of the isomer are equally stable, select both. Select the mote stable conformation of cis-1,2-di(2-methylpropyl)cydohexane. Select the more stable conformation of trans-1,2-di(2-methy1propyl)cyclohexane. Select the most stable conformation overall.

Consider a molecule of hydrogen chloride, HCl. In this molecule, the light hydrogen atom orbits the heavy Cl atom, much like an electron orbits a heavy nucleus in an atom. The energy of H in the molecule is quantized. When exposed to electromagnetic field, the molecule HCl absorbs photons that promote the hydrogen atom to higher energy states, corresponding to faster rotation of H about Cl. What do you think is the approximate frequency of these photons? a) The frequency...
