Global warming is the worst challenge facing the world in the 21st century. Since the second half of the 20th century, there has been sudden increase in global temperature leading to global warming effect. Increased human activities and natural activities have contributed to increase global …
Experiment 16: Heat conduction Introduction In this laboratory you will study heat flow across a temperature gradient. By comparing the temperature difference across one material to the temperature difference across a second material of known thermal conductivity, when both are conducting heat at a steady …
Chp. 15 Chemical equilibrium: Occurs when a reaction and its reverse reaction (opposing reactions) proceed at the same rate At equilibrium the rate at which products are produced from reactants equals the rate at which reactants are produced from products At equilibrium a particular ratio …
Pesticidehe terms “chemical accident” or “chemical incident” refer to an event resulting in the release of a substance or substances hazardous to human health and/or the environment in the short or long term. Such events include fires, explosions, leakages or releases of toxic or hazardous …
Chemotherapy simply means the use of chemicals to treat disease by destroying microorganism or cancerous or tumor cells. Generally, chemotherapy acts by destroying rapidly dividing cells although the mechanism that leads to this differs. Several divisions of chemotherapy agents exist such as the anti-metabolites, plant …
Macromolecules contain more than one molecules. They are usually found in foods. For example, lipids, nucleic acids, carbohydrates and proteins are the living organisms that macromolecules are commonly found. Their functions are mostly storing energy and information. By performing this lab, types of macromolecules are …
Questions A. Give two reasons why we fill the gas generator test tubes almost to the top with chemicals? The first reason is that we want to obtain pure gas and by minimizing the amount of air in the top this will maximize the gases …
“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be …
Introduction The main purpose of this lab was to investigate how temperature, concentration, the addition of catalysts, and the substitution of a more reactive reactant, can affect the reaction. The collision theory explains that in order for a reaction to occur, reacting particles must collide …
