C1 Revision Notes Atmosphere is a mixture of gases that surrounds the Earth. The three main chemical components present in air are Nitrogen‚ Oxygen and Carbon Dioxide. Trace amounts means only a very tiny concentration of gas is present. An element is made up of 1 type of atom. A compound is made up of 2 or more types of atom that are chemically bonded. A mixture also contains more than 2 or more type of atoms but they cannot be chemically bonded. A pollutant is a waste matter that contaminates

Q.6 The management of Anna Industries is considering a plan to terminate a new employee. The action stemmed from documented evidence supplied by the firm’s accounting department that this new employee did not add as much to the firm’s overall output as did a worker hired two weeks earlier. Based on this evidence‚ do you agree that the latest worker hired should be fired? Explain No‚ the latest worker should not be fired if his MP multiply by price is greater than wage‚ which means he adds value

Absorbance of Light vs. Concentration of Colored Solution Introduction: Performing this lab showed the importance of light in virtual drug screening because light can be used in a variety of ways to obtain different kinds of information in research. Light can be used to determine the concentration of DNA or protein in solution‚ tag different objects such as cells‚ protein structures‚ or bacteria in order to determine whether there is a large amount of a certain substance‚ and to determine the size

skill in Chemistry. Steps in balancing equation: 1. Write the unbalanced equation. Chemical formulas of reactants are listed on the lefthand side of the equation. Products are listed on the righthand side of the equation. Reactants and products are separated by putting an arrow between them to show the direction of the reaction. Reactions at equilibrium will have arrows facing both directions. 2 Balance the equation. Apply the Law of Conservation of Mass to get the same number of atoms of every element
