Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

Chemistry Lab Report Jeffrey Kenneth Bangero Introduction Firstly we calculated the mass of the beaker and then we put the assigned grams of sodium carbonate and calcium chloride. Then we add 50 ml of distilled water to each substance‚ sodium carbonate dissolved faster than calcium carbonate. After we mixed both sodium carbonate and calcium chloride and they form a solid precipitate. Then we poured it a funnel with a filter paper to get the solid precipitate. Purpose ● The purposed

PHYS113 Lab1: Coulomb’s Law ABSTRACT Performing this experimentation will allow one to investigate the relationship quantitative relationship between the electrostatic force and the distance between charged objects. First a simply observation was made of the electrical forces on two pieces of tape taking note of their attraction and repulsion. This same phenomenon was observed in the experimentation of two charged spheres. Furthermore the we used this experimentation to determine the

Chemical reactions proceeding until all the reactants are used is a common misconception. Chemical reactions actually behave differently. The general reaction equation is a A + b B → c C +d D in this equation A and B are the reactants forming the products C and D. However‚ unlike the common thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b

investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must control

Acquisition of a Second Order Reaction Abstract Introduction The rates at which reactions occur depend on the composition and the temperature of the reaction mixture. Usually the rate of reaction is found to be proportional to the concentrations of the reactants raised to a power.1 There are many reactions that have a rate law in the form of: (1) v = k[A]a[B]b According to reference1 the power to which the concentration of a species (product or reactant) is raised in a rate law of this nature

will increase the speed of reaction as the greater the surface of the solid reactants‚ the more particles are required to expose and ‘cover’ the capacity of the solid. Increased surface area results in an increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or slower reaction Independent Variable

survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze and convert molecules into combinations of other molecules which is necessary for the

AbstractThe rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For
