2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |

Energy‚ often in the state of heat‚ is involved in chemical reactions and phases changes. Changes in energy‚ can translate in temperature differentiations. In such a case‚ energy is transferred as heat. The quantity of heat exerted in a reaction referred to as (joules) can be identified through the following equation: Heat Exerted= (Mass of Sample) x (Specific Heat) x (Change in Temperature) q=msΔT Within a calorimeter is where the reactions within this lab take place. A calorimeter allows the

21st‚ 2013 MC 205 Week 4 Instructor Rein Chemical Stress Testing A chemical stress test is used when a traditional stress test (called a cardiac stress test) cannot be done. A cardiac stress test requires you to walk on a treadmill or ride a stationary bicycle until your heart rate reaches a level where your heart is “stressed”. You may not be able to participate in this kind of test if you have a condition such as a stroke. In this case‚ a chemical stress test is used. This test is used to help

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
