I was assigned was the element Manganese. The symbol for manganese is Mn. It is number 25 on the periodic table. That means it has 25 protons and electrons even on mars or anywhere you go it will have the same protons and electrons. The atomic number would also be 25. It has 30 neutrons also in in the nucleus. The melting point for Manganese would be 1519 K (1246°C or 2275°F). The boiling point would be 1519 K (1246°C or 2275°F) according to http://education.jlab.org/. It also could be 1245.0 °C

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

FMCG Industry Introduction The fast moving consumer goods (FMCG) sector is a large and important part of almost every economy in the world‚ insofar as the products associated with the industry represents a big part of every consumer budget. The goods produced by the industry are basically necessities and the inelastic nature of the goods makes their impact on economies worldwide significant. The FMCG are sometimes referred to as consumer packaged goods and the various products are characterized

The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.

experiments. We had to go through steps and make observations for each‚ but in the end we had to decide whether the experiment had a chemical or physical change. A physical change can alter the state of matter‚ but not the substances identity. A chemical change transforms a substance from one identity to another. It is important to identify the difference between physical and chemical changes in any lab because you want to know the process of what is going on. The first experiment was the water jug explosion

Observations of Chemical Changes Objectives: (1 of 20 points) The objectives of this experiment are: 1. To observe some properties of chemical reactions 2. To associate chemical properties with household products Background Information: (2 of 20 points) Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature‚ presence of a flame‚ and evolution of light‚ as when as firefly glows. Three physical changes that indicate a chemical change
