Department of Chemistry Chem 180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write

Experiment 3: Stoichiometry of a Precipitation Reaction Abstract: In this experiment‚ the objective is to use Stoichiometry to predict the amount of product produced in a precipitation reaction. We received working knowledge of how to accurately measure reactants and products of the reaction. We then are able to use the data that we recorded to make assessments of the actual yield opposed to the theoretical yield. When we calculated the percent yield we are able

Classes of Chemical Reactions Whenever a reaction takes place‚ energy is changed as well when the substances react chemically. Scientists have taken these changes in energy and generalized them. Scientists can take these generalizations and discover more about the nature and tendencies of matter. In this lab‚ the purpose was to perform seven reactions‚ write down their equations‚ and identify the type of reaction. In this lab report‚ several methods of displaying this information will be applied

Observing a Single Chemical Reaction Qualitative vs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. The results of the experiments were determined through close examination and observation of both qualitative and quantitative elements of the changes that occurred when a blue crystal‚ Copper Chloride‚ reacted with aluminum

chloroplasts‚ where the photosynthesis occurs. During experiment‚ two leaves were tested for the presence and localization of starch. One leaf was a light-grown plant with mask‚ and the other was a dark-grown plant with mask. Both leaves were soaked in iodine solution and then rinsed in order to observe the pattern of staining. According to the result‚ the light-grown leaf’s masked areas had no blue-black coloration and the unmasked area turned blue-black in color. The blue-black coloration of the leaf

CHEMICAL REACTION (SYNTHESIS REACTION‚ DECOMPOSITION AND SINGLE REAPLACEMENT REACTION) Purpose : 1. To identify the chemical changes 2. To observe the effect of temperature of a chemical reaction. Theoritical basic : A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically‚ chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds between

before being killed. I imagine it to be similar to my reaction of seeing a dead dog on the side of the freeway (some sadness if I stop to dwell on the thought)‚ compared to a seeing suffering dog just after being hit by the car (deep sadness to the extent of tears). The Concentration Camp sort of opened my eyes to my inner reactions towards death and my much deeper ractions towards suffering. The Holocaust reading further showed me my reactions to death. As they read countless names of small children

Lab #5 Chemical Reactions & Balancing Equations Objectives Observe and classify several chemical and physical changes. Give evidence for the occurrence of a chemical reaction. Write a balanced equation for a chemical reaction. Identify a reaction as a combination‚ decomposition‚ replacement‚ or combustion reaction. Background Physical properties can be observed without changing the chemical composition of the substance. Common physical properties that can be measured without changing the chemical

Reaction Since I have already read this story as a junior in high school I do not have a very strong reaction to it‚ although I can recall my reaction from when I first read this sad short story. I read this in my AP English class in high school and I had the teacher that stressed how everything had a meaning. Since this skill was already burned into my brain by the time we read this work by Kate Chopin‚ I could easily pick apart and decipher the meaning of this story. I believe that Kate Chopin
