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

Three things are usually required for a chemical explosion: a chemical reaction that occurs very rapidly‚ a large increase in gas pressure‚ and a confined-reaction vessel in which the pressure of the gaseous products can increase to a point that the gases break violently out of the container. In this chemistry and physics science fair project‚ you will use the combustion of ethanol to provide energy for a small explosion. The chemical equation that describes the combustion of ethanol is shown below

already immersed in a lesson-driven environment‚ PLCs do not necessarily operate with a clear focus on teachers’ growth and learning. Reasons for a lack of focus on learning range from weak levels of relational trust to changing administrative expectations and teacher burnout. The end result‚ however‚ in many cases‚ is that PLCs are not easily initiated‚ nor are they designed in a manner that makes professional development a natural by-product of PLC meetings. In fact‚ many well-meaning teachers and

Chemical Nomenclature refers to the naming systems used with chemical formulas. This worksheet focuses on the most basic chemicals and nomenclature systems. Please read the information concerning each problem set and then attempt the problems associated with that information. The simplest compounds contain just two elements. Sodium chloride‚ NaCl‚ is an example of a binary compound. Several other examples are listed below. Potassium bromide KBr Calcium bromide CaBr2 Lithium fluoride LiF

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

Chemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds‚ we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive electronegativity
