Gender Neutral Bathrooms Should gender neutral bathrooms be allowed? This is a very controversial topic in todays society. There are many different points of view and opinions on the subject. Some people support it‚ while others hate the idea. There has been a rise in court cases that deal with this subject lately‚ mostly because of the growing LGBT population. Around 23% of Americas population are thought to be gay‚ or lesbian. But yet only around 4% classify themselves as LGBT. The LGBT population

DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

TECH0701: Measuring the Melting Points of Compounds and Mixtures Introduction This exercise dealt with the melting points of pure mandelic acid and benzoic acid. The eutectic temperature and composition of mandelic and benzoic acid mixtures were determined. And finally‚ an unknown was identified by its mixtures and melting point. The melting point of a compound is used by organic chemists not only to identify the compound‚ but also to establish its purity. To determine the melting point two

Compounds First to define the word‚ compounds are pure substances made up of atoms of two or more elements chemically combined together in fixed ratios determined by mass. When a compound is formed from its components‚ a chemical change takes place through chemical reactions. Elements form compounds to become more stable‚ which happens when the maximum number of possible electrons are in the outermost energy level. Carbohydrates: A carbohydrate is one of the elements of the 5 major compounds

Acid Rain Webquest Name: ________Jacob Rough_________________________ Date: _____3/25/13________ Sulfur dioxide and nitrogen oxides are gases released by the burning of fossil fuels. These gases can react with water and oxygen to form acids. Normally‚ rainwater is slightly acidic. But the additional acid that enters the air when fuels are burned makes it even more acidic. Acid rain can have a harmful effect on fish and other wildlife and upsets the delicate balance
Premium Acid rain Oxygen PH
Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

EXPERIMENT 2 ACID DISSOCIATION CONSTANT OF AN INDICATOR DYE OBJECTIVES Using spectrophotometric method: determine the wavelengths at which the acid and base forms of the dye in aqueous medium exhibit maximum absorption; determine the molar absorptivities of the acid and base forms of the dye and estimate an unknown concentration of the dye in solution using the Beer-Lambert’s Law; and determine the acid dissociation constant of the indicator dye. THEORY The absorption or reflection of
