- What is the magnitude of the partial positive and partial negative charges in the HBr molecule? (1 D = 3.36 ×10–30 C m; 1 e– = 1.6022 × 10–19 C; bond length HBr = 1.41 angstroms; Dipole Moment HBr = 0.82 D).
Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Given that the atomic radii of H and Br are 25.0 pm and 115 pm , respectively, predict the bond length of the HBr molecule. Express your answer to three significant figures and include the appropriate units. in nm please
Part ACalculate the bond energy per mole for breaking all the bonds in methane, CH4.Express your answer to four significant figures and include the appropriate units.ΔHCH4 =1656 kJmolCorrectIn CH4, the energy required to break one C−H bond is 414 kJ/mol. Since there are four C−H bonds in CH4, the energy ΔHCH4 for breaking all the bonds is calculated asΔHCH4=4×bond energy of C−H bond=4×414 kJ/mol=1656 kJ/mol CH4 moleculesPart BCalculate the bond energy per mole for breaking all the bonds of oxygen,...
