Different types are available, suited for different uses. Batteries convert chemical energy into electrical energy. You can make a battery from a lemon, a piece of zinc and a piece of copper. So why don’t we use this instead of buying batteries from shops? In this activity you find out. You also explore other homemade batteries, including a seawater battery made by scientists in the BBC TV programme Rough Science. The purpose is to explore the potential of low technology homemade batteries as emergency power supplies.

...THE USE OF BAKING SODA, COMMON SALT, AND VINEGAR AS FIRE EXTINGUISHER In Partial Fulfilment for the Requirements in Research II Researchers Verchiel B. Cubelo Ma. Rena N. Catoltol Nathaniel L. Perol S.Y. 2014-2015 CHAPTER I INTRODUCTION Nature and Importance of the Study Fire is a reaction involving fuel and oxygen that produces heat and light. Humans use fire to warm themselves and to cook food, and to start a fire, we commonly use lighters and matches, unlike the early humans who rub sticks or rocks. Today, people naturally focus not on starting fire but on using it productively and on preventing or extinguishing unwanted fires using fire extinguishers. These are portable devices used to put out fires of limited size. Such fires are limited into four classes, according to the type of material that is burning. Class A fires include those in which ordinary combustibles such as wood, cloth, and paper are burning. Class B fires are those in which flammable liquids, oils, and grease are burning. Class C fires are those involving live electrical equipment. Class D fires involve combustible metals such as magnesium, potassium and sodium. Each class of fire requires its own type of fire extinguisher. This study focuses on the use of common salt (sodium chloride), baking soda (sodium bicarbonate), and vinegar (acetic acid) as fire extinguisher. Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water (H2O). The acetic acid...

Kasilag, Ian Michael 8- Pascal Febuary 2015 GROUP 7 CHAPER II REVIEW OF RELATED LITERATURE The review of literature for this study focuses on procedures on making power source. The review focuses on the number of light bulbs the vinegar can power. The chapter begins with finding some people who lack power source, followed by the findings of researchers on some information about vinegar, zinc nail and copper wire. What is Vinegar? Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water. Vinegar is now mainly used as a cooking ingredients, but historically, asa the most easily available mild acid, it had a great variet of industrial, medical, and domestic uses, some of which are still promoted today. The history of vinegar is actually by accident, but according to legends, Babylonians used vinegar as a cleaning agent. The Babylonians later discovered that vinegars slows or stop the action of bacteria that spoils the food and so they started using it as a preservative. Vinegar is a totally natural food. There are no harmful chemicals or preservatives in fact vinegar is a preservative itself. Vinegar makes itself when it comes in contact with any aerobic bacteria while it is exposed to oxygen. Vinegar is usually use in making the food last longer...

...potential cleaner. I, the researcher, will try to prove that this commonly consumed drink is also effectively used as cleaning agent in common household tasks. The four experiments involved will be The intended outcome of this experiment is to test a commonly known theory that sodas that have a darker appearance have the ability to break through the common household cleaning issues. This experiment will utilize the popular brand Coca Cola. The experiments will attempt to prove the cleaning ability of the agent by the researcher. This experiment will include the following experiments: • Cleaning food stains on cooking equipment • Cleaning stains on kitchen counters • Cleaning grime in a kitchen sink; and • Cleaning corrosion on the battery connections of an automobile This experiment will compare the variances in cleaning opportunities and compare the effects with that of a commonly known soap coupled with water. This experiment shows that there are commonly used ingredients that could also be used as cleaning ingredients. The experiments will be completed in step-by-step processes where the two cleaning methods will be tested side-by-side so they can prove their outcomes. The researcher will make notes as to the outcomes according to the cleaning methods used. It is important to prove that darkly colored soda products can be as effective as a cleaning agent as simple soap and water. The researcher believes that this experiment will be of social value because, while...

...Chemistry Notes 2010 Core Module 1: Production of Materials Contextual Outline Humans have always exploited their natural environment for all their needs including food, clothing and shelter. As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments. Added to this was a reduction in availability of the traditional resources to supply the increasing world population. Chemists and chemical engineers continue to play a pivotal role in the search for new sources of traditional materials such as those from the petrochemical industry. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. In addition, chemists are continually searching for compounds to be used in the design and production of new materials to replace those that have been deemed no longer satisfactory for needs. This module increases students’ understanding of the implications of chemistry for society and the environment and the current issues, research and developments in chemistry. 1.1 Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: • Acid reactions: o acid (aq) + base (aq) salt (aq) + water (l) o acid (aq) + active metal (s) salt (aq) + hydrogen (g)...

...consumer condiments together with animal feed. It’s primary product is soya sauce along with other cooking and dipping sauce. China Food Company has a very strong brand for cooking and dipping sauces and is currently the 9th largest manufacturer and seller of soya sauce in China, operating three production lines at its plants in Shouguang City and Weifang City, in the central of Shandong province and employing more than 1000 people (www.chinafoodcompany.com). 1.1 History The company was founded in 1994 in China by Mr Fu Guoping and commenced trading as a manufacturer of Compound Feed for poultry, cows and pigs. It established its first factory in 1995 and diversified into manufacturing higher margin condiments like soya sauce and vinegar, which have become its primary products now. The second factory was constructed in 2001, with an integrated production of 40000 tons annually. In May 2010, the Company completed the construction of a modern soya sauce factory in the nearby Shouguang city and later in October 2011 introduced it’s premium soya sauce brand “Xaxa”.

For example, Mr. Jacobs's report of incision pain and his expression of concern about whether the pain means that he will not be able to go home as soon as he hoped are subjective findings. Subjective data usually include feelings, perceptions, and self-report of symptoms. Only patients provide subjective data relevant to their health condition. The data sometimes reflect physiological changes, which you further explore through objective data collection. --Objective data are observations or measurements...
