Phenolic yellowing issues We have been facing yellowing on the fabrics kept at stores‚all the test results were passing like PH‚Phenolic yellowing‚Formaldehyde‚Light and BGF but we couldn;t come to an solution .Hence we have finally kept the fabric exposed in sunlight for a day and found that it has totally became yellow in the exposed area.So please advise whether the fabric stored can be wrapped with a opaque cover and also in the dark room to avoid the issue. 1 month ago * Close viewer

1. The chart and graph below give information about sales and share prices for Coca-Cola. Write a report for a university lecturer describing the information shown below. [pic] You should write at least 150 words. You should spend about 20 minutes on this task. model answer: The pie chart shows the worldwide distribution of sales of Coca- Cola in the year 2000 and the graph shows the change in share prices between 1996 and 2001. In the year 2000‚ Coca-Cola sold a total of 17.1 billion

General Chemistry 2 Study Guide* Exam 3‚ Spring 2014 Chapter 16 (Acid-Base Equilibria) Know the definitions of Arrhenius‚ Bronsted-Lowry and Lewis acids and bases. - Arrhenius: Acid dissolved in water increases conc. Of H+ ions. Base dissolved in water increases conc. Of OH- ions - Bronsted-Lowry: Acid: substance that donates a proton to another substance Base: substance that accepts a proton from another substance -Lewis: Acid: electron pair acceptor

Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: NOTE: In chemistry‚ [x] means “concentration of x” in moles per litre (mol/L). EG: [H3O+] means “concentration of H3O+ ions” in mol/L. BASIC reactions to remember: Acid reactions: acid + base salt + water acid + metal salt + hydrogen gas acid + carbonate carbon dioxide gas + salt + water Formation of hydronium: H+ + H2O H3O+ Reactions of

Acids and Bases Are Everywhere Every liquid you see will probably have either acidic or basic traits. Water (H2O) can be both an acid and a base‚ depending on how you look at it. It can be considered an acid in some reactions and a base in others. Water can even react with itself to form acids and bases. It happens in really small amounts‚ so it won’t change your experiments at all. It goes like this: 2H2O --> H2O + H+ + OH- --> H3O+ + OH- See how the hydrogen ion was transferred? Most of the

factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water has a pH of 5.6‚ acid rain has a pH of 5 or less‚ which is acidic enough to harm plant life. Due to the reactivity of acid rain‚ the cell processes of plants are disrupted‚ and the cells die or become unable to function properly. Although this greatly damages ecosystems‚

essential for life. Without enzymes life processes‚ and life in of itself‚ would not be possible. Enzymes are also special because very little of the actual enzyme is actually used up in the reaction. In this lab two different factors‚ temperature and pH‚ were tested to see what type of effect they would have on catalase‚ a potato enzyme that synthesizes H2O2. The data my group collected supported one hypothesis‚ that an acidic environment would not be conductive to enzyme behavior‚ and disproved another

The research topic is based upon the impact of the abiotic factors on community properties in the aquatic ecosystems of bith La Vega and Caroni Swamp. The abiotic factors to be included ate salinity‚ turbidity‚ dissolved oxygen‚ phosphates‚ nitrates‚ pH‚ and temperature. Aqautic abiotic factors have become a prudent issue in these ecosystems affecting the abundance and distribution of species as well as feeding relationships as seen in food webs and food chains. In order to try to solve this problem

THE EFFECT OF CHANGE IN pH ON THE ACTIVITY OF ENZYMES Introduction: Enzymes are catalysts that speed up‚ and control chemical reactions within a cell and break down complex molecules into smaller ones. Some of the chemical reactions that take place in the body produce toxic by-products which need to be converted. The liver produces hydrogen peroxide‚ which is extremely poisonous. When the catalase comes in contact with the hydrogen peroxide‚ it is broken down into water and oxygen. Aim:
