Purpose To obtain out the densities and to rule out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass, al-Quran, density, extensive properties, and intensive properties. Where do the units for mass and volume) come from and what do they spurious? What is the density of distilled wet system? What is Archimedes principle? Does temperature chance on the density of a solid? fluidity? Gas? Materials Safety glasses, 10, 25 or 50 mL graduated cylindersDistilled water metal Samples W, X,Y &amp Z Procedure 1. Class split into 5 free radicals. Every group will annoy info for four metals and tell it to the level 2. Choose a metal essay for every group consequently crystallize it around between groups. 3. Set a number of your metal essay and study the mass in the table. 4. Get a gradated cylinder with distilled water, but not to frequently to make it over flow when sample is put in. Record the amount of water in the cylinder accurately 5.Then intimation the cylinder to about 45 degrees then put sample into it slowly, DONT spill any water or have to restart. Make sure no air bubbles atomic number 18 clinging. Then eat down final volume of water cylinder. 6. Dump the water out, then teetotal sample off. 7. Repeat this over with the opposite metal samples. * Hypothesis * My hypothesis is that however though I will find the densities and names of the unknown metals its not divergence to be accurate because some water will spill out.Many people are going to come up with the distinguishable names because they arent care mount enough. Mass of metal Initial volume of water Final volume quite a little of metal ExperimentalDensity of metal Group information metallic element W Metal X Metal Y Metal Z Class Data Mass and Volumes of distributively groups metal samples Lab Group Metal W Metal X Metal Y Metal Z 1 2 3 4 5 Total * Class Exp.Density * * 1. raise an deterrent example of how your group calculated the data-establish densities of your group samples and the class samples. 1. Graph the class data using mass as the x axis and volume as the y axis, (title the graph and make a allegory or key for the various metal samples). 1. Compare your groups observational density to that of the classs experimental density from the graph and make note as to their relative accuracies. 1.Research the possible identities of the metals based on their extensive properties (density, radioactivity, heat capacity, conductivity, fatal exposure/dosage, and so on ) and intensive properties (color, texture, luster, magnetism, reactivity, etc. ). 1. Make a claim as to the identity of the various metals based on their extensive and intensive properties. Calculate the % fallacy for each of your claims for both your groups experimental values and the classs. Show an example of each type of deliberation and make a table representing the nonionic results. *
