Chemical reaction and quick lab
At each lab station you must determine if the reaction observed is a chemical or physical reaction in addition, you must cite properties that change as a result of the reaction when making these claims, it will be important that you cite qualitative as well as quantitative data. In this lab, you will study an enzyme that is found in the cells of many living tissues the name of the enzyme is catalase it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen.

Chemical reaction and quick lab
Chemical reactions happen when one or more chemicals come in contact with one another the reaction turns the chemicals into new compounds for example, a lit candle combines carbon in the wax with oxygen in the air, releasing light and giving off carbon dioxide. American chemical society: chemistry for life chemistry moves from the lab and the classroom to the computer, as working in a virtual chemistry laboratory and . Physical changes vs chemical changes lab • what was done • combustion – an exothermic chemical reaction release of heat in form of light or flame. C12-3-03 measure the average rate of a chemical reaction purpose: how do changing reactant concentrations and the addition of a catalyst changes a rate of reaction.

Lab – evidence for chemical change one way of knowing that a chemical change has occurred is to observe that the properties of the products are different from those of the reactants the new product can then become a reactant in another chemical reaction. We are now going to delve into the heart of chemistry we learn ways of representing molecules and how molecules react to do this, we'll even think about how many of a molecule we have using a quantity called a mole.
