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

Lab: Gas Laws Purpose: Obtain a reference of temperatures effect on gas using Charles’ law when heating a capillary tube in water on a heated hot plate. Then‚ cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed using microLAB software. A final determination of experiments determined absolute zero versus actual absolute zero will be

Atmospheric chemistry is a branch of atmospheric science in which the chemistry of the Earth’s atmosphere and that of other planets is studied. Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It can be defined as the study of the sources‚ reactions‚ transport‚ effects‚ and fates of chemical species in the air‚ soil‚ and water environments; and the effect of human activity on these. Environmental chemistry is an interdisciplinary

Coordination Complexes of Cobalt Advanced Inorganic Chemistry Lab 02/27/2015 Abstract When the transition metal‚ cobalt‚ forms a complex involving a nitrate ion‚ the ligand has the ability to coordinate via N or O. The ability of the nitrate to attach via the N or O gives rise to the term‚ linkage isomers and can affect the functionality of the complex with other molecules. To explore structural differences between complexes‚ pentaaminechlorocobalt (III) chloride‚ pentaaminenitritocobalt (III)

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a

pneumatic trough‚ thermometer‚ screw clamp. DISCUSSION The quantitative relationship between the volume and the absolute temperature of a gas is summartzed in Charles’law. This law states: at constant pressure‚ the volume of a particular sample of gas is directly proportional to the absolute temperature. Charles’ law may be expressed mathematically: V ". T (constant pressure) V = kT o‚ : T = k (constant pressure) (1) (2) where V is volume‚ T is Kelvin temperature‚ and k is a proportionality constant

The change in color‚ formation of a gas or a solid product‚ and the production of energy are the evidences of a chemical reaction‚ thus‚ of a chemical change.
