Purpose Since there are two possible oxidation numbers for the iron nails‚ by this experiment we will need to determine the actual oxidation number of the iron in this experiment. Hypothesis As said in the introduction there will be two possible decomposition reactions: Fe (Ⅱ) + CuCl2 (aq) → Cu + FeCl2 2Fe (Ш) + 3CuCl2 (aq) → 3Cu + 2FeCl2 We can measure the mass of the two iron nails‚ and the copper after the reaction. Thus‚ we can compare the ratio of the mole and the mass of iron and copper. Procedure

Decomposition of Sodium Chlorate to Create Oxygen Gas Introduction: There are several types of chemical reactions. Those reactions include synthesis‚ decomposition‚ single replacement‚ and double replacement. In this experiment‚ we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction‚ a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction‚ AB break down into A

Soda Ash Analysis and Volumetric Analysis of a Carbonate-Bicarbonate Mixture De Guzman‚ Danica Justine R. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila Abstract Titration is a laboratory method in which the endpoint of a reaction is determined quantitatively. In this experiment‚ the amount of soda ash present in a sample was determined and the alkalinity reported as it was titrated using HCl as the titrant. Also‚ the percentage

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any

P LANNING Aim: Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance‚ which alters the speed‚ or rate of a chemical reaction but is chemically unchanged at the end of the reaction. The two factors that we can change are the temperature and the concentration. We chose to vary the concentration of hydrogen peroxide. The catalyst to speed up the reaction without affecting the result will be manganese

Candy and soda should be banned from schools‚ since they are the main reason ⅓ of American children are overweight or obese. Unhealthy food keeps getting popular day-by-day. Even though soda and candy taste great‚ there are a lot of negative effects that would be going to end up getting to the person who eats an excessive amount of it. For example‚ the person will get obese‚ they have the risk of suffering from certain cancers and chronic diseases such as: diabetes‚ heart disease‚ asthma‚ and high

Background of the Study Since ancient times‚ farmers have known that adding certain substances to the soil helps produce healthier‚ more abundant crops; such a substance is called fertilizer. The researchers decided to make an organic fertilizer. Organic fertilizers are made up of

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came
