Chemical Equilibrium: Le Chatelier Principle By Sarah Ramos and Kristina Todorovic Chemistry 203 DEN Dr. Mohamed El-Maazawi Part A. Acid-Base Indicators Purpose In this part of the experiment‚ we will find a reagent that will shift the acid-base equilibrium reaction described by Equation (2) in one direction and then a second reagent that will cause the equilibrium position to shift back in the opposite direction. Introduction An acid–base indicator

Chemical Engineering In the future I would like to become a chemical engineer. I really enjoy chemistry and hands on work “Chemical engineering is the application of chemistry to large scale industrial systems.” (Chemical engineering). I enjoy helping build different things like skateboards‚ ramps and‚ fixing parts on different things. When I took the sixteen personality quiz it said I was a virtuoso. The virtuoso likes hands on work and exploring ideas which I think fits my personality perfectly

2 Chemical warfare What is Chemical Warfare: To understand chemical warfare you must first understand what a chemical agent is. A United Nations report from 1969 defines chemical warfare agents as " ... chemical substances‚ whether gaseous‚ liquid or solid‚ which might be employed because of their direct toxic effects on man‚ animals and plants ... ". This means basically that any chemical that is used to directly effect and harm a person‚ plant‚ or animal would be an act of chemical warfare

this problem. Firstly the causes of this problem is the attitude of human. The human attitude nowadays really disappointing. They do not have the love feeling to the nature and throw garbage or any chemical substances anywhere including the river‚ the sea and any water sources. So this chemical substance will harm the water and we as the user will use the water without notice that we use the contaminated water. Slowly or in the long term our body will be affected.
