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 | |

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

Experiment #17 Classification of Chemical Substances Prepared for: Dr. Robert O’Reilly By: Kudaibergenov Baizak 20.11.2013 Nazarbayev University Introduction While many thousands of substances are known‚ they can be classified into a few simple categories based on type of bonding that exists among the atoms in the substance. Bonds are chemical forces that hold atoms together to form molecules or compounds. These categories are ionic‚ molecular and metallic substances.

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

Purpose The purpose of this lab was to observe chemical changes which result in different properties. Procedure First all materials needed for experiment were gathered. Using a sanitized scissor‚ all the pipets were cut open at the very top of the pipet. The 96 well plate was used for combining the chemicals to see what the reactions were and the 12 well plate was used for holding the pipets filled with chemicals that had been opened. In column 1 row A of the 96 well plate; two drops of NaHCO3 was

Experiment 1: Observations of Chemical Changes Purpose: To observe the macroscopic changes that occur in chemical reactions and attempt to interpret the microscopic changes of the atoms and molecules that allow for the macroscopic changes to happen; and to associate these chemical properties with household products. Also‚ it is to learn the importance of how to separate mixtures into their component substances by solubility. Procedure: Before starting with the official experiment‚ it was important
