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 is produced by the fermentation of ethanol by acetic acid bacteria. Baking soda, a base, is an amphoteric compound. It is also known as sodium hydrogen bicarbonate or sodium bicarbonate (NaHCO3). It is a white solid crystalline but often appears as a white powder and has a slightly salty, alkaline taste resembling that of washing soda. It can extinguish fire (grease or electrical) by being…...

Dessert Buffet Restaurant

...University Proposed Potential Market High School and College Students of Zamboanga City, and others Proposed number of employees Ten (10) employees: Manager/Supervisor (1); Pâtissier (1); Commis (2); Steward (1); Cashier (1); Waiters (5); Security Guard (1) Total Project Cost (TPC) P1, 387, 894.84 Return of Investment (ROI) 50% Cash Payback Period 3 years Proposed Financing Scheme The Capital will be equally financed by the project proponents B. Background of the Study In Western culture, dessert is a course that typically comes at the end of a meal, usually consisting of sweet food. The word comes from the French language as “dessert” and this from Old French “desservir” which means “to clear the table” and “to serve”. Common desserts include cakes, cookies, ice-cream, and candies. Fruit may also be eaten with the dessert. The word dessert is most commonly used for this course in U.S., Canada, Australia, and Ireland, while sweet, pudding or afters may be alternative terms used in the UK and some other countries. In Russia, breakfast foods such as Bliny, Oladi, and Syrniki served with honey and jam are also popular as desserts. In England, the term pudding might be used among the Upper and Upper-middle classes, with dessert only used if the course consists of fruit. A buffet is a system of serving meals in which food is placed in a public area where the diners generally serve themselves. In Zamboanga City, food establishment is one of the great......

Experiments

...place in it several shoots of water weed. Place the jar in sunlight, and at once small gas bubbles will rise in the water. Invert a funnel over the plants and over it a water-filled glass tube. The gas, which is given off by the plants slowly, fills the tube. Plants use sunlight. With its help, in the presence of chlorophyll, they make their building material, starch, from water and carbon dioxide, and give off oxygen. Oxygen has actually collected in the glass tube. If you remove the tube and hold a glowing splint in it, the splint will burn brightly. 7. Automatic watering Fill a bottle with water and place it upside down and half-buried in soil in a flower box. An air bubble rises up in the bottle from time to time, showing that the plants are using the water. The water reservoir is enough for several days, depending on the number of plants and the weather. Water only flows from the bottle until the soil round it is soaked. It starts to flow again only when the plants have drawn so much water from the soil that it becomes dry, and air can enter the bottle. One notices that plants can take water more easily from loose soil than from hard. 8. Secret path Dissolve a teaspoonful of salt in a glass of water and cover it tightly with parchment paper. Place the glass upside down in a dish containing water strongly coloured with vegetable dye. Although the parchment paper has no visible holes; the water in the glass is soon evenly coloured.

Hsc Chemistry Notes

...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) o acid (aq) + metal carbonate (s)  salt (aq) + water (l) + carbon dioxide (g) • Cracking of long chain alkanes (e.g. decane) to give a shorter chain alkene & alkane o Thermal cracking (heated with......

Under the Dorm

...and another three waddling steps — although he had been cut in two. Then he fell apart on the edge of the road. Blood squirted and pumped; guts tumbled into the dirt; his rear legs kicked rapidly twice, then stopped. His last thought before the darkness that comes to us all, chucks and humans alike: Wliat happened? 3 All the needles on the control panel dropped dead. 'What the hellV Claudie Sanders said. She turned to Chuck. Her eyes were wide, but there was no panic in them, only bewilderment. There was no time for panic. Chuck never saw the control panel. He saw the Seneca's nose crumple toward him. Then he saw both propellers disintegrate. There was no time to see more. No time for anything. The Seneca exploded over Route 119 and rained fire on the countryside. It also rained body parts. A smoking forearm Claudette's - landed with a thump beside the neatly divided woodchuck. It was October twenty-first. BARBIE 1 Barbie started feeling better as soon as he passed Food City and left downtown behind. When he saw the sign reading YOU ARE LEAVING THE VILLAGE OF CHESTER'S MILL COME BACK REAL SOON!, he felt better still. He was glad to be on his way, and not just because he had taken a pretty good beating in The Mill. It was plain old moving on that had lightened him up. He had been walking around under his own little gray cloud for at least two weeks before getting his shit handed to him in the parking lot of Dipper's. 'Basically, I'm just a ramblin guy,' he said, and laughed.'A......
