Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s

Shelby Brown 8/28/10 Physical and chemical changes lab essay Changes in matter occur every day. There are two types of ways matter can be altered; physically and chemically. Physical changes do not change the composition of the matter while chemical changes occur when one or more substances turn into a completely new substance. Physical changes can be seen through an altering of the substances physical property. A substances physical property is observed and measured without changing

Name: Tom Flannigan Title: Physical and Chemical Properties Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

Physical and Chemical Properties Chem 107 6-4-2013 A pure substance or chemical substance is a material that is homogeneous. It has consistent properties throughout the sample.” Pure substances can be described by both physical and chemical properties”. Physical properties can include‚ color‚ odor‚ melting point‚ boiling point‚ and solubility in various solvents‚ etc. The observation of these physical properties does not involve any chemical change in the substance‚ it is still the same

Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility

Physical and Chemical Changes Say you are presented with two beakers‚ beaker A and beaker B‚ each containing a white‚ powdery compound. * a. From your initial observations‚ you suspect that the two beakers contain the same compound. Describe‚ in general terms‚ some experiments in a laboratory that you could do to help prove or disprove that the beakers contain the same compound. You may try some of the followings: * Dissolving in water * Dissolving in different chemical solution
