What kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam

The Formation of Alum Crystals from Solutions in Two Different Thermal Conditions Burce P.J.‚ Cachuela J.A.A.‚ Capistrano M.M. I. Objectives The experiment aims to describe crystals and its aggregates by creating crystals of Alum (AlK (SO4)2 ∙12H2O)‚ commonly known as Tawas‚ from solution. Two setups will be created; crystals from each setup will be allowed to form at two different thermal conditions. With this‚ the experiment also aims to describe how temperature affects the formation of

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by
