    Goal(s): To study the effect of concentration on the rate of a reaction‚ and to find the order of the reaction in each reactant and write a rate equation. Background Theory: Chemical reactions occur at different rates that ultimately depend on their concentration‚ the temperature‚ the usage of catalysts‚ the nature of reactants‚ like the surface area of the particles. Concentration‚ for instance‚ increases the number of molecules or particles in a certain volume‚ so collisions will become more

    oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest was helium. In fact‚ helium and lab gas had a density below 0. Anyways

    The properties of dibenzalacetone make it a great substance to be used when protecting the skin from the sun. In the experiment performed‚ dibenzalacetone was created from an aldol condensation of 2 portions of benzaldehyde and acetone in sodium hydroxide. The reaction that occurred in this experiment is known as a specific aldol condensation called Claisen-Schmidt. In the reaction‚ the carbonyl of benzaldehyde reacts quickly with the acetone anion to create a hydroxyketone that dehydrates in the
