potassium and chloride is an ionic bond. The potassium becomes a cation and the chloride an anion. The potassium end of the molecule becomes slightly positive and the other end slightly negative. Na – sodium contains metallic bonding. It has a high melting due to the bonding and has strong bonds. Each sodium atom is being touched by eight other sodium atoms and they all share electrons between the nuclei and shells. The electrons can move freely within the sodium metal and therefore can conduct electricity

activity dealt with two-point acuity. Different parts of our body performs a specific function that which they were built to execute. However‚ the sensitivity each surface of our body reveals to be different. Some areas of the body will have a variety of sensory receptors‚ which requires more sensory input. Therefore‚ body parts have their own sensation depth that one can measure through two-point acuity. Results Participant #1: Initially‚ the researcher placed the compass points with one on the tip

RECRYSTALLIZATION AND MELTING POINT DETERMINATION OF BENZOIC ACID ANSWERS TO QUESTIONS 1. How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases

The Melting Pot The myth of the melting pot was created by a man named J. Hector St. John de Crèvecoeur. His idea was that immigrants from all over the world would come together to create a new society. A new race‚ religion and way of life would come from this society. The myth is widely known today and is often related to the United States. America is known to be a melting pot because it is a society made up from people of different race‚ culture and beliefs.

BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the boiling points of various

Canada prides itself at home and abroad as a country made up of a cultural mosaic rather than a cultural melting pot. The mosaic is based on our belief that Canada as a whole becomes stronger by having immigrants bring with them their cultural diversity for all Canadians to learn from. The cultural melting pot‚ as adopted in the United States‚ tells immigrants that no matter who they have been in the past‚ upon landing on American shores‚ they are Americans and are expected to adopt and follow the
