Assuming the heterocyclic ring above to be planar: give the number of electrons that are contributed to the pi system of the heterocyclic ring by: atom 1; atom 2 ; atom 3 . enter na for atom 3 if the structure above has only two numbered atoms. how many electrons are in the pi system of the heterocyclic ring? (in the case of fused rings add all the pi electrons.) is the heterocyclic ring with the numbered atoms aromatic? submit answer

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32Ã10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^â1 mol^â1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022Ã10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
