chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved. Two drops of a chemical were placed in a well along with two drops of another chemical. Chemical reactions and color changes were recorded in Data Table 1.

PI-100 A Reaction paper on Prehispanic class structure‚ law and order The nature and force of human to put order into various things is strong in this topic. This phenomenon of organizing is as ancient as history itself. Even before the birth of colonialism‚ several groups of people had already established an organization to live much easier and to control the ever growing population of the human race. One can also account this strategic technique in the ancient times of our archipelago (what

Reaction Paper about Martial Law On September 21‚ 1972‚ President Ferdinand E. Marcos placed the Philippines under Martial Law. The declaration issued under Proclamation 1081 suspended the civil rights and imposed military authority in the country. Marcos defended the declaration stressing the need for extra powers to quell the rising wave of violence allegedly caused by communists. As I watched the 11 clips of Martial Law‚ different feelings showed up in me. At first‚ knowing that a bright Filipino

Purpose: To determine the reaction order with respect to crystal violet dye. Procedure: Turn on a Spectronic 20 and warm it up for at least 15 minutes. Be sure the wavelength is set to 540nm. When the instrument has warmed up‚ use a clean small test tube from the drawer filled 2/3 with the first NaOH solution that is planned to use‚ as a blank set 0% and 100% transmittance. Take a %T reading every minute for at least 15 minutes so it may be convenient to wait until the room clock’s second

Affect the Rate of a Reaction BACKGROUND: Chemical reactions occur at different rates. In this experiment I will consider some of the key factors that influence the rate of a reaction: * nature of reactants - particle size * temperature * catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the collisions

Measuring Reaction Rate using Volume of Gas Produced By John Doe 23th October 2012 Introduction An essential element of chemistry is finding reaction rates. This is because chemists need to know how long a reaction should take. In addition to needing to know the rate of a reaction at any point in time to monitor how the reaction is proceeding. Many factors effect reaction rates‚ two shown above include temperature and concentration. Concentration affects the rate of reactions because the
