Chemical Periodicity ------------------------------------------------- ABSTRACT The experiment chemical periodicity shows the properties and reactions belonging to group IA‚ IIA‚ and IVA. Proper procedures and observations were done to determine the solubility‚ physical state‚ color‚ and appearance of the compounds namely Li2CO3‚ Na2CO3‚ K2CO3‚ CaCO3‚ and BaCO3. The results shows that Li2CO3‚ Na2CO3‚ K2CO3 were soluble in water‚ while MgCO3‚ CaCO3‚and BaCO3 were not soluble. All of these compounds

Are Ethics Relative? Ruth Benedict: Ethics Are Relative ID # : 0804014743 “Ruth Benedict: Ethics Are Relative … Morality is culturally relative.” In this paper‚ I’m going to discuss the argument that the famous American anthropologist‚ Ruth Benedict‚ has put forth regarding ‘ethical relativism’. Ethical relativism is the theory that holds that morality is relative to the norms and values of one’s culture or society. That is‚ whether an action is classified as right or wrong depends on the moral

and soon to be traitor to the Americans. Benedict Arnold was a huge hero to many of the patriots and many looked up to him. Little did they know he was making a plan for the patriots to fail at West Point. Because Benedict Arnold’s plan was discovered by the patriots‚ the British were at a great disadvantage during the American Revolution and this led to the birth of a new nation.

Chemical Periodicity Gorospe‚ Jheremy Alden B. ____________________________________________________________________________________ ABSTRACT The experiment Chemical Periodicity was demonstrated by using different samples of Group IA‚ Group IIA and Group IVA elements. We placed each of the samples in each test tubes and the physical state‚ color‚ and appearance was identified. We determined the solubility of the elements by using distilled water. We used red and blue litmus paper for the Group

Experiment 1: Observations of Chemical Changes Purpose: To observe the macroscopic changes that occur in chemical reactions and attempt to interpret the microscopic changes of the atoms and molecules that allow for the macroscopic changes to happen; and to associate these chemical properties with household products. Also‚ it is to learn the importance of how to separate mixtures into their component substances by solubility. Procedure: Before starting with the official experiment‚ it was important

I mostly agree with Ashley’s opinion‚ but I do not believe Silver Linings Playbook is a formalistic movie. This is not a formalistic movie because there are no distortions or manipulations of reality (Giannetti 7). Also‚ formalistic movies use highly manipulated images that they look so different from the real thing ( Giannetti 524). They want the manipulated images to look beautiful or attractive to the eye (Giannetti 524). Silver Linings Playbook does not use manipulated images because the images

HOW FAST ARE CHEMICAL REACTIONS? THEORY The study of reaction rates‚ how fast or how slow a reaction takes place‚ is known as chemical kinetics. The rate of chemical reactions varies greatly. Some reactions‚ such as the explosion of an atom bomb are uncontrollable. Reactions like the decay of radioactive carbon (14C) are so slow that it takes centuries to see any noticeable change. Between the two extremes are reactions that can be measured in the laboratory. There are several factors that
