Data observation Essay Example for Free

Data observation EssayComplete a data table that includes a prediction of reply type ( oneness replacement, double replacement, synthetic thinking, decomposition, or burning), observations, and identification of reaction type for each reaction in the lab. (10 points)ReactantsPrediction of Reaction TypeObservationsReaction TypeIron (III) and copper (II) sulfate eventsingle replacementSolids stay concentrated at the bottomSingle replacementLead (II) treat and potassium iodide solutions treble replacementYellow colored powder collected at the bottomDouble replacementMagnesium metal and hydrochloric acid solutionSingle replacementThe solution began to fizz. Proves to be flammable.single replacementElectrolysis of waterdecompositionThe water bubbles In the tubes filled with H2 and O2decompositionBurning magnesiumcombustionAs the magnesium comes in contact with the CO2 it creates a bright burning light synthesisConclusionWrite a balanced equation for each reaction observed in this lab. (10 points)2Fe + 3CuSO4 = 3Cu + Fe2(SO4)3Pb(NO3)2 + 2KI = PbI2 + 2K(NO3)Mg + 2HCl = MgCl2 + H22H2O = 2H2 + O22Mg + O2 = 2MgOIf you were to measure the mass of magnesium and hydrochloric acid before combining them in the test tube, how would that mass match to the mass of reactants left in the test tube after the reaction? Explain your answer and how it corresponds to the legal philosophy of conservation of mass. (5 points) -The mass would be the same as it started. This is because the law of conservation of mass states that energy cannot be created nor destroyed only changed.One of the reactions you conducted can actually be categorized as TWO incompatible types of reactions. Which reaction is this, and what are the two types of reactions? (5 points) It would be the Magnesium metal and hydrochloric acid solution because it bubbled but it remedy stayed in its form and didnt change. It is single replacement or combustion.
