Calculate the value of E^circ and Delta G^circ for the following reaction. 2Fe^2+(aq)+Br_(2)(aq)leftharpoons 2Fe^3+(aq)+2Br^-(aq) K=4.85times 10^10
Hybrid orbitals can be occupied by electrons in isolated atoms all have the same shapes and energies when formed around a single central atom have similar shapes to s, p, and d orbitals in isolated atoms create sigma and and n bonds pi
Valence bond theory describes covalent bonds as the overlap of half-filled orbitals with electron pairs localized between two bonded atoms uses a combination of atomic orbitals to create molecular orbitals with electrons delocalized throughout the entire molecule creates bonding and anti -bonding interactions based on which orbitals are filled correctly predicts paramagnetism in molecules
Question 22 (8 points) Match each orbital type with the maximum number of orbitals possible: square porbital square d orbital square forbital square s orbital 1. 1 2. 3 3. 7 4. 5 5. 9
Match each process with whether it is endothermic or exothermic: square A candle flame 2 square The freezing of water square v The combustion of butane square v Photosynthesis square pack used for injuries The chemical reaction in a cold square The vaporization of rubbing alcohol 1. Endothermic 2. Exothermic
