Experiment #9: Infrared Spectrometry 1: Sampling Methods and Qualitative Analysis Corrales, Monique V. Go, Carleen Jade M. Ms. Stephanie Chan February 20, 2014 March 13, 2014 I. Abstract This experiment aims to introduce the different infrared spectrometry sampling techniques and also to identify an unknown solution using qualitative analysis of the solution’s infrared spectra. There are a total of three (3) sample mounting techniques introduced in this experiment namely

1) Look up the chemical/health hazards for sulfur!. Main Routes of Exposure: Inhalation. • Inhalation: VERY TOXIC, can cause death. Can cause severe irritation of the nose and throat. At high concentrations: can cause life-threatening accumulation of fluid in the lungs (pulmonary edema). Symptoms may include coughing, shortness of breath, difficult breathing and tightness in the chest. A single exposure to a high concentration can cause a long-lasting condition like asthma. If this occurs, many

Introduction: In this lab a series of experiments were done to gain a greater understanding of photosynthesis, plant pigments and light absorption and transmittance by/through plant chlorophyll and accessory pigments. Photosynthesis is the process by which plants use energy from light (i.e. the sun, photons, electromagenetic energy), water, and carbon dioxide to produce ‘food’ for themselves, or some for of sugar, like glucose. Photosynthesis has two stages which take place within the chloroplasts

Determining Enzyme Specificity in chemical reactions Introduction Enzymes are proteins that catalyze chemical reactions by speeding up the rate of the reaction and are usually named for the substrates they work on most with –ase suffix e.g. Substrate- Lactose, Enzyme- Lactase. Every reaction requires activation energy to begin and without the aid of enzymes chemical reactions require high levels of activation energy and would be too slow to support life within cells. Since every chemical reaction

Combustion Lab Lukas Worcester PGHS Introduction The concepts of hydrocarbons, combustion, specific heat capacity, and endothermic reactions must be understood by the students to complete the lab. Carbon and hydrogen molecules are what actually make up hydrocarbons structure. Hydrocarbons are typically utilized in fuels and lubricants, as well as raw materials such as plastic, rubber, and other materials. The reaction between a hydrocarbon and oxygen is a process called combustion

By definition electrochemistry is the science that deals with the relation of electricity to chemical changes and with the inter-conversion of chemical and electrical energy (Definition of electrochemistry n.d.). The process of an electrochemical reaction is one which is either caused by the movement of current or a result of the movement of electrical current. This process is commonly known as a redox (oxidation-reduction) reaction (Conjecture Corporation 2014). In this process one atom/molecule

Introduction: Metformin (1, 1 Dimethylbiguanide hydrochloride ®Glucophage) is a semisynthetic biguanide derived from the alkaloide substance galegine of a herbaceous plant Galega officinalis (gout rue). It is the only member of beguanide class of oral hypoglycemic drug, [1] generally accepted as a first line treatment for type 2 non-insulin dependent diabetes mellitus (NIDDM).[2] Metformin exist as a hydrophilic cation, reduces the blood glucose levels by overwhelming hepatic gluconeogenesis and

Introduction An isopod is an insect that survives in moist areas hidden under mulch, rocks, or wood collecting nutrient from the soil and decaying matters. A Sowbug is a scavenger and therefore thrives in moist area where they feed on decaying waste such as leaves, wood, and soil. The purpose of this experiment was to determine the preference sowbugs have when given the option between natural and artificial food choices. If scavengers depend on moist areas for decaying matter, then the presence of
