Chemical reaction

of this lab is as follows: a chemical change is a type of reaction where the original substance changes into another substance, also commonly known as the process of a chemical reaction. Every chemical reaction has an equation which can help determine what type of reaction it is. The five types of chemical reactions are synthesis reactions, decomposition reactions, single-replacement reactions, double-replacement reactions, and combustion reactions. A synthesis reaction is when two or more elements

Chemical reactions usually involve the absorption or release of energy, often as heat. When a chemical reaction occurs at constant pressure, the energy released is equal to the heat flow and is known as enthalpy. Heat is a form of energy that flows into or out of a system because of temperature differences. If a reaction releases heat, it is exothermic; if a reaction absorbs heat, it is endothermic. The enthalpy change of a reaction is measured using a calorimeter, an insulated device that prevents

Kalah Bailey October10th 2015 Chem 109 Pre-Lab 6 Title: Observations of Chemical Reactions. In this lab, students will recognize and record the chemical reaction results of seven different anions and one cation. This experiment also focuses on the reaction of salt solutions and what happens when two different solutions mix. Procedure: • Carbonate (CO32-) - First, solid calcium carbonate (CaCO3) is added to a test tube in a small amount. Next, 15 to 20 drops of 6M HCl are placed in the tube. The

addressed regarding this explosive reaction that we have covered in our class: chemical reactions, catalysts, and gas laws. Chemical reactions are where one or more substances are changed into another or multiple other substances based on the properties of the reactants. We learned about 4 types of reactions; Synthesis or where reactants A & B combine and create product AB, Decomposition where substance AB is broken apart into substances A and B, Substitution reaction where reactants A and BC get rearranged

order to obtain data regarding the reaction and outcome. For each reaction, a test tube is needed and the desired amounts of each substance to be used. A Bunsen burner, tong, and droppers were also needed to perform the experiments. Proper standard lab attire is needed to perform the lab, along with gloves, an apron, and protective goggles. This is to avoid any harm for each student. The first experiment to be conducted was the synthesis/combination reaction, a piece of copper wire and magnesium

Classification of Chemical Reactions Lab Purpose: I. The objective of this laboratory experiment is to be able to identify and precisely classify each reaction as one of the five different types of chemical reactions by comparing the reactants from the product. II. The purpose of this laboratory experiment is to accurately calculate quantities of the products and the reactants, Aluminum and Copper (II) Chloride, in the chemical reaction to determine its percent yield. Data Tables: I. Reaction #1 Observation

Observing Chemical Reactions lab called for us to determine from a list of possible chemical formulas which chemical reaction is the most green to run. From here we concluded from a list of chemical reactions as to which chemicals are the least hazardous to people and the environment. After choosing which experiments to work on as a group we then conducted the experiments individually. The reactions that we decided to pursue were A1, B2, C1, D1, E1 and F2. After concluding which reactions should be

In this lab there was a performance of a single replacement chemical reaction. The reactants of the reaction was solid iron metal, and copper (II) sulfate solution. This was a gravimetric lab and therefore it was crucial to begin by massing the reactants individually. The copper (II) sulfate was initially a solid. A procedure was conducted to dissolve the copper (II) solid by heating it in water to create the necessary solution. Once that was complete the following action was to react the solid iron

There are five main factors that affect that rate of a chemical reaction. These are the surface area of a solid reactant, the concentration and pressure of a reactant, temperature, the presence or absence of a catalyst and agitation. There is also another factor which is able to affect the rate which is the nature of the reactants. The surface area of a solid reactant can speed up a reaction. This is because if a physical change is made to the substance than the particles originally on the inside

Conservation of mass: How is copper transformed in chemical reaction? There were 3 objectives for this lab they were demonstrate that mass is conserved in chemical transformations, practice balancing out chemical equations for reactions observed in the lab and practice the skill of recognizing chemical reactions and making detailed observations. Part A of lab (preparation of copper (II) nitrate from copper metal). Weigh out ~ 0.2 g of copper foil pieces (record to the nearest .001 g) into a weigh
