Chemical reaction

familiar with the products of different types of chemical reactions by conducting several chemical reactions and observing the changes that occurred. In addition, by performing various experiments, the observations will help in writing chemical equations, which represent the process involved in a chemical reaction. Overall, the chemical changes observed throughout can determine the products that are formed from the reactants. In chemical reactions, substances that are referred to as reactants produce

Jack Zhou Eric Lonrenzo Chemistry section # Date Chemical Reactions Introduction: The purpose of the lab was to create and observe the 4 kinds of chemical equation, and to identify reactants and products of those reactions. The four kinds of chemical reactions are synthesis, decomposition, single-displacement and double-displacement. Materials: Bunsen burner, sparker, tongs, 5 test tubes, scoop, wooden splint, lead(II)nitrate, magnesium wire, copper(II) carbonate, hydrochloric acid, zinc, potassium

006/7th Review of Literature A chemical reaction is the “communication” (or interaction) between elements (Green, 2012). Chemical reactions can happen naturally or can be caused by a person. They can even happen inside of a living being (Newmark, 2000). Some chemical reactions can just happen randomly and others need different amounts of energy for them to occur. Heat can provide chemicals with the energy for this to happen. For example, dynamite is extremely

Chemical reactions occur every day almost continuously, both in the natural world outside as well as inside living organisms. These reactions occur at varying speeds, but are usually considerably slow. Some reactions can take as long as seven years for the molecules to undergo the reaction process (Berenbaum 153-154). However, with the presence of an enzyme in the reaction, this process speeds up considerably. A reaction that takes seven years to complete, now takes less than a second to finish

affect on chemical reactions and the rate at which these reactions are happening. Procedure 1. Nature of the Reactants • Obtain 4 small test tubes and label them while, placing them in a test tube rack. • Fill each test tube half way with 4 different acids as shown in Figure 23.3 (use safety precautions while handling acids). • Obtain a 1-cm strip of magnesium and place it within each test tube. Make sure the strip is completely immersed within the acid in order to get a clear reaction rate. •

Finding the Ratio of Moles and Reactants in a Chemical Reaction Objective The objective of this experiment was to find the mole ratios of the reactants and products for the chemical reaction, without being given the products. Neda Samya Emma & Nisha Fri. 09/11 Procedure 1 I measured the temperature of NaCIO solution and “solution B” (using the same thermometer; temperature of solutions were equal). Then recorded my data in the table. 2 I poured 5.0 ml of NaCIO into a Styrofoam cup and then

In this lab, students observed reactions, or lack thereof, between metals Mg, Cu, Zn, and Fe; when placed in solutions of Hydrochloric acid (HCl), Cu(NO3)2, Zn(NO3)2, Fe(NO3)3 and Mg(NO3)2. Students were tasked with observing whatever reaction took place and recording the characteristics of said reaction. To set up the lab, students placed a piece of each metal in a pocket on a spot plate. The plates had four pockets in a row, one for each metal, and 3 rows of pockets. Students would then put a solution

Background Information: A chemical reaction is the change of a substance into a new one that has a different chemical identity (Chemical Reaction , 2015). It rearranges the atoms of the reactants to create different chemical elements or compounds. Chemical reactions occur because an atom is trying to get a full outer shell of electrons. A chemical reaction is usually accompanied by easily observable physical effects such as the emission of heat and light, precipitate, gas and colour change (Factors

Classifying Chemical Reactions Introduction Pre-lab questions 1. Which reactants used in this experiment are flammable? Discuss the safety precautions that are necessary when working with flammable materials in the lab? 2. Summarize the following description of a chemical reaction in the form of a balanced chemical equation? 3. Common observations of a chemical reaction are described in the introduction section. For each observation, name a common or everyday occurrence that must involve a chemical reaction

Two chemical reactions occurred in our lab and I have evidence to prove why. To start, the main purposes of the lab were to make two chemical reactions (which are the two main ingredients in the antacid Maalox), to learn about why changes in solubility, state, appearance, pH, and energy indicate that the chemical reaction really happened, and to learn about balanced equations and classifying them. In Part 1, we combined alum and ammonia to make aluminum hydroxide, potassium ammonium sulfate, and
