The theory thatexplains the paramagnetism of O 2 is to be determined. Concept introduction: Lewis structures are two dimensional structures showing the lone pairs and bond pairs present in a molecule. The VSEPR model helps in predicting the shape of molecules on the basis of their Lewis structures. The valence bond theory explains the formation of covalent bond on the basis of overlapping of singly occupied orbitals. The concept of hybridization of atomic orbitals explains the observed bond angles and geometry of a molecule. The concept of hybrid orbitals explains the formation of required number of orbitals with unpaired electron that can participate in the bond formation. Molecular orbital theory helps in predicting the magnetic properties of molecules. Paramagnetic substances contain unpaired electrons while diamagnetic substances contain paired electrons.

Question

Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.

Dr. Mendel asked his BIOL 260 class what their height was and what their parent's heights were. He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
