Chemical reactions are a part of everyday lives. Whether it is the burning of propane at a kitchen stove‚ or washing detergent reacting with dirt stains‚ chemical reactions are useful tools that have widespread applications. With so many reactions assisting our everyday activities‚ it is important that ways to optimise reaction rates are investigated. “Reaction rate‚ the speed at which a chemical reaction proceeds… may be defined in terms of the amounts of the reactants consumed or products formed

In this lab‚ we were given three experiments. We had to go through steps and make observations for each‚ but in the end we had to decide whether the experiment had a chemical or physical change. A physical change can alter the state of matter‚ but not the substances identity. A chemical change transforms a substance from one identity to another. It is important to identify the difference between physical and chemical changes in any lab because you want to know the process of what is going on. The

Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

The aim of this experiment it to analyze the solution of Ba(OH)2 of an unknown concentration. In order to obtain the quantitative analysis‚ the exact amount of a particular compound or element present in sample‚ two procedures were performed. The first procedure was by conductimetric titration and by gravimetric determination. The conductivity was analyzed during the reaction between the sulfuric acid (H2SO4) and barium hydroxide (Ba(OH)2). Through the conductivity‚ the equivalence point can be determined;
