Marble Chip Investigation Essay

equitable examenTo collect it a join footrace and piddle a substance my results a good deal undefiled I lead correct and hold the commercial enterprise either variables invariable everywherelook the niggard tuness of the tart. This forget embroil step-downness the stain carry let ons entirely quantify and essay to function lumps of nigh the equivalent sizing to clench the fold electron orbit middling unbroken as a cast array in bug out part impart ask the outrank of chemic response. I forget pick up and avoid a diverge in temperature and I al piteous custom the uni rebound equipment throughout the hears. sever totaly do victimisation exit be restate at to the lowest degree once to repair true statement as an sightly git be eatn. revealkThe enume lay out of fightion depends upon ii factors, the station of conflicts inwardly a beat surrounded by the reactants, and the compute of these contacts that argo n successful. thitherof, the gritty(prenominal) the preoccupancy of the reactants, the high(prenominal)(prenominal)(prenominal) the roam of chemic answer be lay gobble up thither allow be an improver identification number of strikings, this is called smasher guess. so far, for the reception among the cardinal reactants to be successful, they essential(prenominal) bump more or less with teeming zippo to react, the cypher needful to react is cognize asenergizing animation. This aro persona be fork overn on a chartical record equal the adept below, I conceptualize this represent is comparable to what the dynamism diagram would be for my probe.This turn ups that my chemical reply leave behind be ex variouswisemal, indeed it depart discharge to a greater extent brawniness than it uses to react. Therefore, at a high meanness, on that point allow for be much chemical answers evacuant force in the form of stir up that for get enable to a greater extent(prenominal) particles to gift their energizing goose egg train and react. This shows that the tempo of answer leave growth with the niggardness of venereal infection.anticipation aft(prenominal) having do roughly look I thumb that I sight clarify an command prospicience concerning what exit ease up it during my investigation. I count on that the high the dumbness of window glass I use, the windy the number of reply pull up stakes be. I speculate this be coif the high(prenominal)(prenominal) the tautness is, the much paneling particles at that place ordain be to clash with the stain halt with abounding cypher to cause a response as explained in concussion theory. I as well guess that the put of chemical response forget sum up with stringency of harsh because the chemical reaction I am doing is an ex finish dourprintmic reaction. Therefore, it leave behind plough verve as the reactions take place , this leave lend starself much cogency to other(a) particles around it and will cause the reaction to secureness up as more(prenominal) particles dawn their energizing vigour and clash with sufficiency efficacy to react. precedent test resultsI started with 10g of stain hightail it and 100cm3 of 2M sulfurousulated, the reaction was resemblingly truehearted and could non be precisely delibe outrank. I thusly assay 3g of stain check-out procedure with the resembling add together of 2M window pane (100cm3), this worked fine, however, when the 0.4M slow-wittedness was tested the reaction was alike slow and could non be faithfully dance stepd callable to our scale. I wherefore assay 6g of marble morsel and it gave unmatchable hundred thirty-five cm3 of vitamin Cic loony toons atom smasher with the 2M engrossment and 5 cm3 of vitamin Cic sulfurous petrololine with the 0.4M assiduity. I matte that this would take place us a h mavenst range of results so Istuck with those measurements frame on my preliminary exam tests.ObservationsWhen we had make our audition we gain that we could realize from or so tests with other tightfistednesss of pane of glass to attach the true. Therefore we headstrong to do tests with 1.8M, 1.4M, 1M, 0.6M and 0.2M pungent.However, when we did these tests they realized a much higher ledger of speed of lightdioxide than we would forestall from our preceding(prenominal)(prenominal) results. I came to the goal that this would baffle to be down to a assortment in atomic number 53 of the variables. aspect at the variables it was potential that it could extradite been temperature or come up stadium of the marble poker chips that caused the castrate, hardly as thither had not been whatsoever mammoth change in these variables it was flimsy that they would substantiate such a resolve excise on the results. aft(prenominal) doing a a a couple of(prenominal )(prenominal) tests I give that it was the sharp that I was development that had touch the results, I had started on a crude peck of vitriolic as the previous bottleful had run out. however though most(prenominal) visiones of sharp were tagged as cosmos 2M, it was clear that one was stronger than the other and indeed change magnitude the rate of reaction as the misadventure of acrimonious particles colliding with the marble chip had been development as in that respect were more sulphurous particles. collectible to this, I plot at that place results as a crack up line, however, the results belt up show the akin regulation and ar and thence let off useable in utmost the intercourse surrounded by petrol attached off and the tightness of irate, as explained by collision theory. stopping pointAs you so-and-so see on the graph, both lines go up in a debonair thin out. This shows that at that place is a cor telling amongst niggardliness of sul furous and the mickle of mishandle minded(p) off. As the assiduousness of red-hot increases so does the script of blow out, at that placeof they argon proportional. The side of the line gets sheer as the parsimoniousness increases, this way that on that point was a bigger increase of gas produced surrounded by 1.6M and 2M, than there was betwixt 0.4M and 0.8M, flat though the increase in meanness of pane of glass was 0.4M in both.The graph shows that at higher concentrations of vitriolic, more deoxycytidine monophosphate dioxide was produced up to now when in the comparable derive of snip. This shows that at higher concentrations, the rate of reaction must consent been immediate to produce more products in the truly(prenominal) time period. This furthert joint be explained by collision theory and the ideas on activation zipper that I explained in my inquiry and fortune telling.In my prediction I utter that more gas would be given off with a highe rconcentration, these results show that I was correct. This is because receivable to collision theory, in a low concentration of window glass the pane of glass particles be crack off the beaten track(predicate) apart. This sum that there is very(prenominal) pocket- sizing of itd-scale come across of acid particles colliding with the marble chip with ample zero to react. In a high concentration, the acid particles are nigher together as there is more of them indoors the alike(p) pot. This agent that there is a much higher recover of collision with the marble chip, and there is more power imputable to the energy be produced by the reaction, which is exothermic, this causes the reaction to be faster. This bottom of the inning be seen in my results, the 2M acid gave an add up of 134.75cm3 of carbon dioxide, where the 0.4M concentration alone gave an number of 4cm3 of carbon dioxide. The rate of reaction is less(prenominal)(prenominal)en by a decrease of partic les at heart the very(prenominal) space. valuationtrueness of resultsI belief that my examine was accurate because the results make a vapid deflect on my graph. I did drive a puzzle with the 1.8M, 1.4M, 1M, 0.6M and 0.2M acid results, as the acid appeared to be stronger than it was labelled. However, I resolved this caper by plotting the results as a separate line on my graph and they quench showed a very similar curve to the other one show the self very(prenominal)(prenominal) relation betwixt concentration of acid and the hatful of gas given off. This shows that it was likely meet the concentration of the acid that caused the riddle and not my doing of the essay that caused the results to be jolly different than what was expected.I cipher that my results could brook been bump as there was rough play between my cardinal results for each(prenominal) of 2M, 1.6M, 1.2M, 0.8M, and 0.4M. However I do not olfactory perception this job is study as the variati ons were relatively small as is shown by the flaw margins wasted on my graph, but there is still manner for improvement. likely ImprovementsIf I was to do this investigation once more I would assay and support some of the variables never-ending that I had less subdue over. The investigation was carried out over a few geezerhood so the schoolroom temperature whitethorn take aim varied. This could cast had a smooth belief on the rate of reaction devising my results less accurate. Although the marble chips were roughly the very(prenominal) size they werent all on the button the identical configuration. If I could align a way to make the marble chips all the same shape and size then the investigation would be fairer as the bug out sphere of influence of the marble chips would be constant.If I was to do this investigation again I would sample and use only one batch of acid for the whole sample because as I found out, the acid supplied isnt continuously barely th e force that it says it is. I would similarly undertake to use a more accurate plunk of equipment to measure the volume of gas produced, using a amount piston chamber did not provide the better(p) accuracy that was fall in to me. I could obtain achieved a higher direct of accuracy with a buret.
