    order to gain stability with each other (Larsen). To have stability which each other‚ the atoms share electrons so that their outer electron shell is equal. Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions (Larsen‚ 2010). Element that have a positive ion are able to bond with elements with negative ions. This is because the elements share the electrons so that the ionization becomes neutral and both atoms

    Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to

    The purpose of this lab was to find the empirical formula for magnesium oxide. To find this formula‚ a strip of Magnesium ribbon was burned in a crucible over a flame from a bunson burner. After the strip caught fire multiple times with the cover on‚ and 10 drops of distilled water were added‚ and the crucible was lightly heated. The crucible was then weighed and the mass recorded. Calculations were performed and the mole ratio of Mg to O was recorded. The results of other lab groups performing

    Cost‚ Volume‚ and Profit Formulas Heather Jauregui University of Phoenix of Axia College “The Cost-volume-profit (CVP) analysis is the study of the effects of changes in costs and volume on a company’s profits.” (Kimmel‚ P.‚ Weygandt‚ J.‚ & Kieso‚ D. 2003) The analysis is used to maximize efficiency in a business. In order to be effective the CVP analysis has to make several assumptions. These assumptions are that the costs can be fitted into either fixed or variable categories. The

    Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD
