Vector A B has a magnitude of 145 units and points 35.08 north of west. Vector B B points 65.08 east of north. Vector C B points 15.08 west of south. These three vectors add to give a resultant vector that is zero. Using components, fi nd the magnitudes of (a) vector B B and (b) vector C
Lecture 1 objectives 1.Describe the different kinds of chemical bonds Covalent Bonding between 2 nonmetals; sharing of electrons creating bounding Polar sharing electrons unequally Nonpolar sharing electrons equally Ionic Bonding between a metal and nonmetal: complete transfer of electrons resulting in two charged atoms that are then attracted to each other Cation + charged ion Antion charged ion Hydrogen bonding because hydrogen is the smallest atom it usually has polar bonds which results in a partial positive charge which allows for weak attraction to a negative ion 2.Explain the structure of water and how it works as a solvent The structure of water is bent, which means it has
