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

Introduction: During an enclosed chemical reaction, “chemical equilibrium” is the state in which both reactants and products are at a constant concentration that has no further intention to change. This state results in the forward reaction proceeding at the same rate as the backward reaction. The concepts of chemical equilibrium came about in 1803 by finding that some reactions are reversible. Therefore, the rates of the forward direction are directly proportional to the reverse reaction rate. In

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

apply the knowledge of chemical reactions to identify an unknown substance. Research was done prior to doing the experiment to provide a basic understanding of the chemical reactions occurring. There are two elementary aspects a chemical solution. First, there’s the reactant. The reactant is the substance added that reacts with another chemical, after the chemical reaction has run its course, what is left is called the product. There are about seven ways to tell if a chemical reaction has taken place;

recorded different household chemicals and their reactions with chemical reagents. The purpose of this lab was to sharpen our powers of observations and deduce from observed reaction to identify household chemicals. The investigation allowed us to make comparisons of reactions and pattern recognitions. The four household chemicals used in the experiment are Lysol Toilet Bowl Cleaner, baking soda (Arm & Hammer), Vanish Crystal Bowl Cleaner, and Clorox Liquid Bleach. These chemicals were reacted with five

Chemical Bonds Lab Paper Shawn Guillot & Kiara Wilson There are many types of chemical bonds and forces that bind molecules together. The two most basic types of bonds are characterized as either ionic or covalent. In the lab we separated Citric Acid, Calcium Chloride, Sucrose, Potassium Iodine, Phenyl Salicylate ,and Sodium Chloride into two groups ionic and Covalent bonds .The Chemical Difference between ionic bonding and covalent bonding is, a covalent bond is formed between two nonmetals

effects that temperature has on a reaction, be able to calculate the reaction’s rate constant, and to calculate the activations energy from the recorded rate constant. Activation energy is the minimal amount of energy that is necessary to result in a chemical reaction. With an insufficient amount of energy, a reaction won’t occur, too much and it will react just fine. A great example of this can be lighting a match. The friction created when striking the tip covered in Potassium Chlorate against the match

Because of a chemical attack on Syrian civilians, people, including children, are struggling to breathe as their mouths begin to foam. The Syrian leader, Bashar al-Assad, has been identified as the culprit in ordering the use of chemical weapons on the Syrian people. The chemical weapons ultimately killed hundreds of innocent people including women, children, and the elderly. The identified chemical is called “Sarin Gas,” which is a very deadly gas according to the United Nations. Based on the agreement

A summary of knowledge that must be known before the performance 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

Chemical Warfare Chemical Warfare is a brutal, terrifying form of warfare that shouldn’t have even happened. Chemical warfare, first appearing long ago in the form of poison arrows and disease, is a form of warfare that involves the use of noxious chemicals with the intent to kill or maim large groups or areas. Whereas in ancient times poison came in the forms of herbs and elements, science today creates gases that stop the heart or cause immense pain. Chemical warfare is different from nuclear
