1.Draw the Lewis structure for phosphoryl chloride ( Cl3PO ). Optimize formal charges. 2.Arrange these bonds from most ionic to most covalent in character.
K-F, Ca-F, Cl-F, Br-F, F-F

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
