Please use the characteristics of chemical bonding, crystal
structures and dislocations to explain why metallic materials are
strong and ductile and why ionic and covalent materials are strong
but brittle?
Please describe what the following molecules and structures
tell scientists about the evolution of the three domains: flagella,
nuclear membrane lipids, ribosomes, grana, cell membrane lipids,
DNA genomes, mRNAs, and types of DNA polymerase.
1.Please describe how hybridization tells you about chemical
structures? What is a good rule of thumb about where groups are
arranged around any central atom? Provide a reaction mechanism
(i.e. movement of electrons shown) for an organic reaction to
illustrate the answer from 1 , and explain how the shape of the
molecule changes during a chemical reaction
