Determination of Cations and Anions through Elimination and Confirmation Tests By: Symantha Resendiz Introduction A topic of great importance to all scientists is the identification of compounds‚ which is relevant in all aspects of their work in some way shape or form. Weather it may be determining what is causing sickness or what is polluting the air‚ it is very prevalent in the science world. In project 2‚ identification of cations and anions was preformed through a series of confirmation

Standard Solution (Part A and B) ABSTRACT The purpose of this experiment is to prepare a standard solution of potassium hydrogen phthalate and use titration to perform an acid/base reaction between the potassium hydrogen phthalate and sodium hydroxide to standardize approximately 0.10 M sodium hydroxide solution. To prepare the Potassium Hydrogen phthalate‚ a 2.00 grams of KHP was measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution

In the article written by Robert Sparrow called‚ “Implants and Ethnocide: Learning from the Cochlear Implant Controversy‚” the topic of cochlear implants is explored to a deeper level. This article takes the controversy a step further by bringing forward the question about genetic testing. Suggesting that if parents could have their unborn children tested for deafness‚ they would have a higher chance of getting an abortion and terminating the pregnancy. Furthermore‚ if people have this kind of

Examine the way Shakespeare presents the power and control Capulet exerts within the play. Power and Control is the main theme in Shakespeare’s play‚ Romeo & Juliet. Power is presented by fate‚ love and parental control. Shakespeare clearly demonstrates that Lord Capulet is a very protective father. This is because in Act 1 scene 2 Capulet says “ hopeful lady of my earth” In this quote Shakespeare shows that Capulet is a loving and protective father because children died easily and the words

The graph shows that the respiration rate does increase as the yeast concentration rises‚ but levels off and eventually reached its saturation point‚ or decline‚ which occurs at 8.5g. This decline may occur because there are too many yeast molecules in comparison to the glucose‚ which may lead to yeast cells hindering a collision thus lessening the reaction. The respiration rate increases as more yeast is added because it gives more opportunities for molecular collisions and so the amount of successful

highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand how sugar affects yeast growth. First of all yeast is a fungus‚ meaning that it needs sugars to supply it energy. Yeast can also release oxygen like human beings‚ called respiration. So technically speaking the more sugars there are the more

‘Amoretti’ describes the various changes that take place in the lover during the courtship. It follows the tradition of the poet Petrarch‚ whose sonnets dealt with a wooing male lover. Petrarch arranged his sonnets into ‘sonnet consequences’ or ‘sonnet cycles’‚ in which series of sonnets were linked together by a common theme based on the various aspects of the lover’s relationship. Spencer also arranged his ‘Amoretti’ in ‘sonnet sequences’. Spencer himself evolved his own structure for the English

PURPOSE What sugar will get the most rise out of yeast‚ so you can get the best bread or baked goods possible. Sugar when mixed with yeast and water will produce carbon dioxide. The carbon dioxide from the yeast sugar and warm water will make the balloon on top of the water bottle blow up. I hypothesize that brown sugar will make the balloon blow up the most HYPOTHESIS If I were to mix brown sugar‚ with yeast‚ and warm water together it should have a different reaction as opposed to other sugars

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule
