Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

Topic 11 - Yassine Assim Question: Explain the concept of a conjugate acid-base pair. Using equilibrium law and K‚ explain the relationship between the strength of an acid/base and its conjugate. Conjugate Acid-Base Pair: Conjugate acids and bases were presented by Bronsted-Lowry‚ who was a chemist who proposed the theory that both acids and bases required the transfer of a proton in order for there to be a reaction. An acid will donate a proton (proton donor)‚ forming what is considered to be a

Ozone depletion‚ greenhouse effect‚ and acid rain are man-made disasters. The ozone layer is the part of the Earth’s atmosphere which contains relatively high concentrations of ozone (O3). The cause of ozone depletion is the presence of Chlorofluorocarbons (CFCs) and related halocarbons gases in the atmosphere. In the presence of Ultraviolet light‚ these gases dissociate‚ releasing chlorine atoms‚ which then go on to catalyze ozone destruction. The greenhouse effect‚ on the other hand‚ is a natural

But-2-enedioic acid Introduction Cis-trans isomers are a kind of stereoisomers called geometrical isomers. Due to the inability of rotation about the C=C bond‚ some compounds possess cis and trans isomers. But-2-enedioic acid is an example of having both isomers. Maleic acid Fumaric acid Cis and trans isomers have different physical properties such as boiling point‚ solubility‚ density and stability. In this experiment some maleic acid is converted to fumaric acid by

Acid Attack: Should the punishment be more stringent? Ways to maim or murder our women- It never gets old. Sometimes they are killed in the womb itself‚ and if they are lucky enough to survive they are doused in kerosene and set alight‚ dragged and‚ raped‚ or Acid is thrown on their faces –perhaps the worst form of torture. Acid attack results in a living death‚ a lifetime in hell on earth. The victim becomes pariah‚ outcast from the society‚ employment and sometimes from their families too.

Introduction This lab’s purpose was to determine whether Salicylic Acid made from methyl salicylate is the same as Salicylic Acid made from benzene. This information can be found by comparing the difference in melting points of the two samples of Salicylic Acid. Here are the physical properties of Salicylic Acid and the mechanism of reactions that occurred in this lab. How Salicylic Acid is derived: Procedure/Results First‚ .26mL of 2.0mmol methyl Salicylate was measured and put

Investigate the Effect of Acid Rain on Building Materials Question: What is the effect of 6M sulfuric acid (H2SO4) on the corrosion rate of the 3 grams of steel as the amount (number of sprays) of sulfuric acid increases? Variables: Independent variable: the number of sprays of 6M sulfuric acid (0‚ 5‚ 10‚ 15‚ 20‚ 25 times) to observe its effect on the corrosion rate. Each spray will contain about 10mL. Dependent variable: The corrosion rate. It will be calculated by measuring the mass of steel

development is Folic acid‚ which is also known as folacin‚ or folate. This nutrient is essential for the prevention of anemia‚ since it is used to make the extra blood a woman’s body needs during pregnancy. Folic acid deficiency anemia is characterized by red blood cells that are larger than normal when referring to this type of anemia. The red blood cells are also deformed‚ and both their rate of production and their lifespan are diminished (Charlish and Holt 65). Folic acid anemia occurs most often
