1. Define the term chemotherapy. Use of chemicals for therapeutic effect is called chemotherapy. 2. Why do we need to classify drugs in different ways ? It is useful for doctors because it provides them the whole range of drugs available for the treatment of a particular type of problem. 3. How are drugs classified? (a) On the basis of pharmacological effect For example‚ analgesics have pain killing effect. (b) On the basis of drug action It is based

Health Assessment and Health Promotion Plan James Padilla FDU Abstract Constipation is a common condition that affects people of all ages. It may be described as a variation in an individual ’s normal bowel habit with discomfort and diminished quality of life. Medical assessment is required as the underlying cause may be due to a serious medical condition. Managing patients with constipation presents many challenges to the health care professional‚ not only overcoming

GASTRO ESOPHAGEAL REFLUX DISEASE (GERD) General Description of GERD It is one of the most common diseases‚ greatly affecting health care and contributing to the expenditure in the United States of nearly 12 billion dollars per year for antacid medications. GERD affects nearly equal proportions of men and women‚ but a male predominance occurs in esophagitis and Barrett’s esophagus. Increasing age is an important factor in the prevalence of GERD complications‚ probably the result of cumulative

Chemistry Lab #1 THER 368: Heat of Neutralization Objective The purpose of this lab was to: * Determine the heat of neutralization for the reaction of sodium hydroxide (NaOH) and hydrochloric acid (HCI). Requirement The heat of neutralization (∆Hneutzn ) is the heat transferred when 1 mol of an acid reacts with 1 mol of a base. This heat is generally reported in either kilojoules per mole (kJ/mol) or kilocalories per mole (kcal mol). The reaction of HCI and NaOH solutions

and have a high H+ concentration‚ and bases from 7 to 14 with a low H+ concentration. Neutralization happens when an acid and base react together and the base is consumed. The product is a neutral solution of water and a salt. HCl (acid) + NaOH (base) changes to H2O and NaCl (water and salt). The purpose of this lab was to determine what happens when and acid reacts with a base‚ and how to detect a neutralization.

Experiment 9 and 10: Volumetric/Vinegar Analysis Abstract: The goal of the experiment that was conducted was to figure out both the molar concentration of NaOH and the standard mole ratio of the NaOH solution. In order to find the concentration of the NaOH solution‚ volumetric analysis was used. In volumetric analysis‚ a titration mechanism was utilized in order to find the reaction that the base will end up having with KHC8H4O4

Stoichiometry February 28th‚ 2013 Abstract: The reactions of the Sodium Hydroxide and two acids‚ Hydrochloric Acid and Sulfuric Acid were performed. The heat given off by these two reactions was used to determine the stoichiometric ratio and the limiting reactants in each experiment. Introduction: Coefficients in a balanced equations show how many moles of each reactant is needed to react with each other and how many moles of each product that will be formed. Stoichiometry allows us to
