VINEGAR AND LEMON AS A HAND SANITIZER AN INVESTIGATORY PROJECT TO MS. RHEA SIENES OF THE SCIENCE DEPARTMENT OF MARY HELP OF CHRISTIANS SCHOOL CEBU INC. In partial fulfillment in Science Submitted by: Regina Lim Rationale: Nowadays a lot of us Filipinos get sick easily. According to the experts, it is because of the germs we accumulate as our day progresses. These germs could pass from one person to another or by just touching anything and doing our day-to-day

------------------------------------------------- ABSTRACT Recrystallization is the simplest and most widely used operation for purifying organic solids that differ in their solubility at different temperatures. In this experiment, three test tubes with water, hexane and, ethanol, respectively, were used to dissolve pure acetanilide. These test tubes were placed in a water bath for one to five minutes, then, were cooled through running water for the selection of the best solvent to use in recrystallization. Crude acetanilide

saponification. It is reverse of Esterification. For example, O O O ANS [c] Dehydration means removal of a molecule of water. When ethanol is heated with conc. H2SO4 at 443K, it undergoes dehydration to form ethene. 2. An organic compound A having molecular fomula C2H4O2 reacts with Sodium metal Na evolves a gas B which readily catches fire. A also reacts with Ethanol in the presence of concentrated Sulphuric acid to form a sweet smelling substance C in making perfumes. a) Identify the compounds

ELIMINATION VERSUS SUBSTITUTION IN HALOGENOALKANES This page discusses the factors that decide whether halogenoalkanes undergo elimination reactions or nucleophilic substitution when they react with hydroxide ions from, say, sodium hydroxide or potassium hydroxide. Details for each of these types of reaction are given elsewhere, and you will find links to them from this page. The reactions Both reactions involve heating the halogenoalkane under reflux with sodium or potassium hydroxide

prevents the growth of bread mold? Firstly, the way hand soaps kills bacteria is that it contains active ingredients which consist of either ethonal or isopropanol, both are forms of alcohol. Ethonal and or isopropanol kill most germs on contact. Both ethanol and isopropanol are antiseptics that kill the germs they are in contact with by dissolving their essential protein.

Industry Overview: Craft Breweries & Microbreweries Craft breweries and microbreweries produce beer in limited quantities when compared to large breweries (generally under 10,000 barrels per year) and usually distribute their beer within a limited geographic region. Craft breweries often specialize in specific styles of beer, and focus on providing customers a superior product, using traditional brewing techniques. Certain craft breweries sell beer directly on their premises, and are called brewpubs

Cellular Respiration Ben Gipson BIO 1400 Exercise 6.1 Alcoholic fermentation is a metabolic pathway used primarily by yeast and some bacteria. In fermentation, glucose is broken down into ethyl alcohol (ethanol) and carbon dioxide. In the process, some of the energy that had been stored in the glucose bonds is used to form high energy bonds in ATP. Name some factors that affect enzyme activity. Temperature, pH, enzyme concentration, substrate concentration Materials: yeast, test tubes,

The Effects of Maltose on Yeast Fermentation By: Arushi Renschler Pandey, Elyana Singh, Isabella Menza, and Janeliz Pereira Does the production rate of yeast change when using different energy sources? Hypothesis: If maltose is used in fermentation rather than glucose, then more CO2bubbles will be produced because maltose is a larger compound than glucose. Special Materials needed: 3 ml of glucose solution 4 ml of yeast suspension 3 ml of maltose solution 37℃ Water bath 2 test tubes Celsius

1. How is the discovery of beer linked to the growth of the first "civilizations"? The discovery of beer led to the growth of the first “civilizations” because it offered a healthy way to hydrate the body and its production came from available food products, such as gruel. To provide this new drink and make it available to others, they began to farm and tend to their lands. It became of great cultural importance to hunter-gathers, which made the substance well known among communities after just
