Acids

The intention of this experiment was to find out which of the two hormones, Gibberellic Acid or Brassinosteroids, would have the greatest effect on growth among our test subjects, the organism Arabidopsis thaliana. The results of this experiment were not as we hypothesized. Gibberellic acid proved superior in cell elongation, which can be observed by way of plant height. This was a rejection to our original hypothesis, as well as a contradiction to the study: “Interactions between…

: This table quantifies the number of amino acids that are different in the same position of the amino acid sequence of myosin heavy chain 6 alpha protein in zebra fish, cod, tilapia, salmon and flounder. The sequence alignment from the NCIB website is used to compare the genetic sequence of myosin and determine how closely related two species of fish are based on the number of amino acid sequence they have in common. The table indicates that flounder and tilapia have the least variation in the…

bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid. When an acetic acid and baking soda (sodium bicarbonate) are mixed together, three new chemicals are formed, Water (H2O), carbon dioxide (co2), and sodium acetate (C2H3Na02). When one of the three chemical atoms breaks off, it creates the chemical reaction. Vinegar Vinegar is an acetic acid, which is produced by the fermentation of ethanol by acetic acid bacteria (Google.com/vinegar). For the purpose of the experiment,…

constant variable is the acid which is in the flask. When the solid acid dissolves to form ions, 1 mole of H+ ions are produced for every mole of acid being used. Molarity is used to calculate moles per liter of solution. The most dangerous part of this lab is the risk of getting…

Polylactic Acid (PLA) Polylactic acid begun to be commercially produced and directly used in the 1990’s, as it was manufactured in large quantities and used for profit. Since then, continuously increasing amounts are being produced, as more is being used in everyday items. The biopolymer is a renewable source, as it is derived from plants, in particular corn crops. Development of Polylactic Acid 1. Corn starch is harvested from corn crops. 2. The starch undergoes hydrolysis to break the bonds…

calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed at the end point. This experiment is a success as two results obtained from the experiment were relatively close furthermore, an average of 21.50% of calcium carbonate obtained is close to the literature value of 20%. 2. Introduction There are several…

in the formulation of soap and also to produce the average quality of soap bar using basic formulations from palm oil. Generally, soap is a salt of a compound and it is known as a fatty acid. Most soap is produced either by using sodium or potassium. Its molecule has a long hydrocarbon chain with a carboxylic acid group…

Determining the Rate of Photosynthesis and the Effect That pH Has on It Abstract - The purpose of this experiment was to determine what variables affect the rate of photosynthesis. The variable tested was the pH level of the “environment” and this was tested using leaf discs from a plant. By testing the leaf discs in different pH levels of two, four, six, eight, and ten, it was found that the rate of photosynthesis was at its highest in a pH of six. It was also found that the rate of…

Oil and water are two different concepts that are believed to not mix. Normally, when pouring oil into water or vice versa, the two separates instead of mixing. However, when they do mix, both oil and water complement each other. The concept of the three main religions, Judaism, Christianity, and Islam, can be explained through the idea of oil and water. When these religions mix, they create something special. Each religion has two different ways of viewing God even though it is the same God. In…
