Report Submitted: February 17‚ 2013 Title: Physical and Chemical Properties Purpose: To investigate and learn the physical and chemical properties of pure chemical substances. Procedure: I used various different tools to investigate the different physical and chemical properties‚ such as blue and red litmus papers‚ beakers‚ and wells. Data Tables: Substance Name Color Odor Heat Effect Cold H2O Hot H2O Litmus Test Dilute HCl Dilute NaOH Mg Silver None None None Not soluble‚ small bubbles Red

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

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

Observations of Chemical Changes Purpose: The purpose of this experiment is to predict and examine chemical changes/reactions among common chemicals found in consumer products at a macroscopic level. Procedure: The procedure of this experiment was to carefully mix different chemicals together using the chemical filled pipettes and the 96-well plate and determining what chemical reactions occurred.

My Chemical Romance. Gerard‚ Mikey and Frank all had drug problems. Mikey and Gerard‚ on top of that had alcohol problems. They got themselves better. They knew no one else could help them. What encouraged them to get better? Themselves‚ and the music. Ray had the absolutely awful job of having to watch them go through all of this‚ on top of him trying to be the perfect guitarist. Frank would do drugs over the weekend‚ and wake up on Monday not knowing anything that had happened. Mikey felt

batch reactor to study reaction kinetics under ideal conditions. This experiment was carried out in other to study effect of temperature on reaction rate constant and also to study the effect of the reaction rate constant in a batch stirred tank reactor its important in chemical industry because it is used to determine the effect of temperature on reaction rate constant; it is also used in chemical and process industry for solids dissolution‚ product mixing‚ chemical reaction‚ batch distillation‚ crystallization
