The aim of VCL is to provide more immersive virtual environment to users by using 3D interaction with chemical items and to simulate their chemistry experiments on high school level. Operations: Click on a dropper to position it over the plate. In order to determine what reactions occur when you mix acids and bases of different strengths, you will have the freedom to mix solutions of these and interpret the resulting salt reaction products. Procedure: Follow the procedure given in the virtual lab. In exothermic reactions the temperature goes up, in endothermic reactions the temperature goes down. You won't spill any acid on the spectrometer in this lab. Word equations included for all reactions. Chemical Engineering. INTRODUCTION: For the processes of life (such as breathing and digestion) the body carries out thousands of biochemical reactions every second. Liquid form. Get Started Note to instructors: If you have any suggestions for additional virtual lab exercises (perhaps using different reactions and/or focusing on different concepts) or additional questions to add to existing exercises -- or any other feedback -- please feel free to drop us a note at info@sciencebysimulation. types of chemical reactions design lab Chemical reactions can be classified in many ways.
