Chemistry 30 Chemical Bonding – Properties of Molecules 1. For the following molecules determine which atoms are bonded (write the symbols with a bond between them)‚ the electronegativity difference between them‚ and the type of chemical bond it represents. If the bond is ionic‚ state what ions are produced. If the bond is polar covalent‚ indicate the direction of the dipole on the symbols from the first part. a) KCl Electronegativity difference = K - Cl = 0.8 - 3.0 = 2.2 ionic bond

Purpose: The purpose of the lab was to investigate and demonstrate hydrogen bonding and London dispersion bonding in water and rubbing alcohol. Hypothesis: I believe water will have the greater surface tension because rubbing alcohol’s density is lower than water’s. Materials: * Water * Isopropyl alcohol (rubbing alcohol) * Pennies * Paper clips * Flasks * Cups or jars * Wax paper * Eyedropper Procedures: Part 1: Surface tension and vortex: * Fill

communicate in a variety of social settings using theory of mind to think about and create meaning on a constant basis (Cooper and Kane‚ 2002). In addition‚ the use of language also allows humans to exchange ideas‚ self-express‚ and create complex social structures. Although humans might believe that their communication skills are superior there is evidence to suggest that animals also make use of a communication system through ‘complex ways’ (Cooper et al‚ p. 75). For example‚ honeybees can convey important

Among all of these bonds as a special bond -- the type a mother or father forms with his or her newborn infant. Bonding does not refer to mutual affection between a baby and an adult‚ but to the phenomenon whereby adults become committed by a one-way flow of concern and affection to children for whom they have cared during the first months and years of life.

This week we did a lot of things. When we came in on Monday we did a team bonding exercise. We first got into groups and elected a leader‚ recorder and timekeeper. The leader conducted interviews with us and everyone in the group got to know a little bit more about each other. The next activity we did was a human knot. We all has to join hands and then get untangled from each other. That activity made us get physically close but we had to communicate and we also laughed a lot. Anytime you laugh with
