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

commercial and service centers in terms of economic activity. For these reasons therefore‚ there are a lot of problems encountered as describe by the Municipal planning and development officers in terms of information dissemination. The municipality uses the manual process of disseminating information about its achievements and activities. This is because only few among the constituents know about the different activities. It is not being disseminated in a wider scope or coverage such as in nearby

Biological Bases of Behavior Nervous System Made up of neurons‚ which are the nerve cells. These send electrical impulses to one another ( through a process known as firing) telling the body what to do. The parts of a neuron include: Cell Body (a.k.a. soma) – Main part of neuron; contains basic cell parts such as nucleus‚ ER‚ etc.; also has dendrites extending from it. Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension

Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

BASE ISOLATED BUILDINGS What is base isolation? When a building is built away (isolated) from the ground‚ resting on flexible bearings or pads known as base isolators. It is of the most popular means of protecting a structure against earthquake forces. HISTORY The first evidence of architects using the principle of base isolation for earthquake protection was discovered in Pasargadae. One of the world’s first base-isolated structures – the William Clayton building Base Isolation

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

have a decent living life to provide for one’s family. Jobs could be easier to obtain when having a higher education. Lewis and Zaidane said " 53% of recent college graduates are either unemployed or not putting their degree to use." "When the economy picks up the job market is more likely to become competitive." (pg 587). Which means someone who has a degree will be more likely to get the opening job opportunity rather than a person who has no degree‚ Each citizen in most countries have the right
