The trans theoretical model (TTM) (Prochaska and DiClemente‚ 1979) proposed that any health behavior change is not automatic but it involves progress through five stages of change. The individual’s cognitive level and behavior decisions differ from each of the five stages. Trans theoretical model interventions are mostly delivered by first identifying the stage in which the individual is present and his/her willingness to change. These changes could be lifestyle changes. The TTM is based on the

Experiment Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pH balanced and neutral? Information Gathered pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid has a sour taste‚ hence‚ will react to metal and will be corrosive; therefore‚ they are considered as an electrolyte

What is required is serious obedience—doing what my Father wills. I can see it now—at the Final Judgment thousands strutting up to me and saying‚ ‘Master‚ we preached the Message‚ we bashed the demons‚ our God-sponsored projects had everyone talking.’ And do you know what I am going to say? ‘You missed the boat.

Tablets I. Introduction An acid-base titration is a method of neutralizing strong acids. Unbeknownst to many‚ acid-base titrations occur on a daily basis. Our stomachs use acid to help us digest our food – approximately .155 hydrochloric acid (HCl) with a pH of 2-3. When too much of this acid is formed in the stomach‚ heartburn and other discomfort occurs. This is when people grab for their antacids; these are bases that neutralize the excess acid in the stomach. Calcium carbonate

Introduction Extraction is a purification technique used in organic chemistry to separate compounds from a mixture of two or more compounds. There are three different extraction techniques: liquid-liquid extraction‚ solid-liquid extraction and chemically active extraction. All three types of extraction follow the same principle. Organic molecules dissolve in organic solvents and polar molecules dissolve in aqueous solvents. This phenomenon is observed because of the intermolecular forces between

Name: Soo Jin Park Date: 03/30/2015 Exp 4: Properties of Gases Lab Section: 73426 Data Tables: Hydrogen Step B: Describe the zinc and acid reaction. As placing a small piece of Zn(mossy zinc) metal into the test tube containing the diluted HCI(Hydrochloric Acid) solution‚ gas bubbles rose from the solution slowly at the beginning and vigorously in process of time. As this reaction continued for a long time‚ transparent solution turned into white opaque color and black precipitates were formed

BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following

AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with

Mozart: Piano Concerto No. 23 in A Major In my introduction to music class we were assigned to listen and evaluate a particular piece of music in order to reflect on our unique individuality. For my project I chose Wolfgang Amadeus Mozart 1756-1791 and his work of the piano concerto No. 23 in A Major specifically the second movement that was created in 1786. In addition to listening‚ the piece must be broken down and organized into themes or motives. By the end of the project we should be able

to practice common organic laboratory techniques inside the lab to get one oriented to the basic methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form‚ consisting of benzoic acid‚ methyl orange‚ a common acid/base indicator‚ and cellulose‚ a natural polymer of glucose (Huston‚ and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating
