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

is the first element on the periodic table and is the most reactive. It only has one proton and one electron. It is the most abundant element in the universe. It is cheap to buy and it was used in some ships a long time ago. It didn’t go so well. Another fact about hydrogen is that our sun converts 600‚000‚000 tons of hydrogen into 596‚000‚000 million tons of helium. The rest of it is converted into energy (according to Einstein’s law: E= mc2) and is sent to earth. That makes the light of dawn‚ the

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

The bond between a young bride and a much older husband is one always filled with much confliction‚ but security. In the short story “Another Evening at the Club” we explore this very bond. Samia‚ a Muslim woman who have found herself to be suited with a man‚ a rather wealthy‚ important man named Abbond Bey. Within the story‚ Samia displays much submissive behaviors while Abbond shows more dominant traits. These two factors radiate the idea of how Samia plays the role she has been practicing for

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

Chemical equations are the symbolic representations of chemical reactions that are made up of reactants and products. It is made up of the chemical formulas of the reactants and the chemical formula of the products. The reactants are the substances or chemicals that takes part in during a reaction and the products are the chemicals are the substances that result from the chemical reaction. Reactants are on the left side of the chemical equation and the products are on the right side of the chemical

Explain in your own words what it means for a chemical system to be in the state of dynamic equilibrium. All reactions are able to reach equilibrium but only if they it happens in closed systems. Dynamic equilibrium is a state of balance where forward and reversed reactions happen at the same time.
