Reactants Lab Essay

panorama 1 Problem What type of chemic reactions occurs when different reactants are change integrity?Variables Manipulated faction of reactantsResponding Type of chemical substance answerControlled 1. resembling amount of reactants utilise (1 piece for hards, 4 drops for fluid states)2. Spot family is washed before reactants are mixed3. Same amount of time centre of attention is completelyowed for chemical substance reaction to occur (15s)4. Because entropy is qualitative, observations exit be made by the same person. setting 2 lordly Variables The same amount of reactants being used will be controlled by exploitation the same amount of reactants in individually reaction (1 piece for solids, 4 drops for swimmings).Spot plate will be washed before each chemical reaction (using the piddle from the squeeze bottle) to find no remnant is left from antecedent reaction.Observations will be made 15 seconds after the chemical raction. Time will be kept using a watch.T he same person will turn over qualitative observations, to ensure that observations are kept consistent. expression 3 Materials Spot cuticle Forceps Squeeze Bottle filled with water ToothpickList of ReactantsFig. 1.1Reactant chemic Formula atomic number 13 (s)Al (s) horseshit (II) chloride (aq)CuCl2 (aq)barium hydrated oxide (aq)Ba(OH)2 (aq) sulfuric venomous (aq)H2SO4 (aq)chlorine (aq)Cl2 (aq) atomic number 11 bromide (aq)NaBr (aq) zinc (s)Zn (s) fuzz (II) sulphate (aq)CuSO4 (aq)hydrochloric acidic (aq)HCl (aq)atomic number 12 hydrated oxide (aq)Mg(OH)2 (aq)calcium chloride (aq)CaCl2 (aq) atomic number 11 carbonate (aq)Na2CO3 (aq)calcium (s)Ca (s)water (l)H2O (l) atomic number 11 acetate (aq)C2H3NaO2 (aq) milligram (s)Mg (s) atomic number 11 hydroxide (aq)NaOH (aq) carbon monoxide chloride (aq)CoCl2 (aq)List of Chemical ReactionsFig. 1.2Reactant 1Reactant 2sulphuric acid (aq)barium hydroxide (aq)hydrochloric acid (aq)magnesium hydroxide (aq)calcium (s)water (l)hydrochloric a cid (aq)sodium acetate (aqzinc (s) tomentum (II) sulphate (aq)cobalt chloride (aq)sodium hydroxide (aq)magnesium (s)hydrochloric acid (aq)sodium bromide (aq)chlorine (aq)aluminum (s)copper (II) chloride (aq) procedure1.

Referring to Data in Aspect 2 & 3 of Data Collection and Processing, we net see there were 5 champion substitution reactions, and 4 double surrogate reactions ( wholeness of which was a neutralization reaction). The reactions involving an element and a compound were all single replacement reactions, and the reaction involving two compounds were double replacements (which include a neutralization reaction).Aspect 2 Evaluate the Procedure A enigma with this procedure is that it doesnt explore all types of chemical reactions. Also, try as one may, it is sometimes difficult to get the rest of a substance off the spot plate. This tampers wi th results.Aspect 3 Improving observational Design A few more(prenominal) reactions should be added where simple composition and decomposition reaction are shown. Also, using the Bunsen burner, a reaction should be added where hydrocarbon combustion is shown. liquid spot plates should be used, to ensure that residue left by previous reactants and reactions, do not tamper with results.
