Gas Laws Lab Essay

IntroductionThe 4 rudimentary physical properties of a gunslinger sample are pressure, gaudiness, temperature, and compute of moles. The spate simply indicates the volume of the container since a gasconade will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases, the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number of moles indicates the amount of gas particles.Gases do not have a definite shape of volume. Gases spread surface into their container and occupy the entire volume available, which means they are free to fire around and have large amounts of empty space. In many chemical substance reactions, gases are produced for example, reactions involving metal hundredates that react with an acid produce gaseous carbon dioxide. ObjectiveTo determine the volume of gas produced from a reaction surrounded by a metal carbonate and acid and to determine the identity of an little-known carbonate salt.Pre-Lab Questions1. If you increase the temperature what happens to the speed of the particles? Explain. 2. What is the formula to convert Celsius temperature to Kelvin? a. C+273.15=K3. What are the standard conditions for a gas? Are you at standard conditions in the lab? 4. Boyles Law The principle that the volume of a given mass of an ideal gas is inversely comparative to its pressure, as long as temperature remains constant. Boyles law is a subcase of the ideal gas law. P1V1 = P2V2 Charles Law The law of volumes. The volume of a unconquerable amount of gas at constant pressure is directly relative to the Kelvin temperature of the gas. (Temperature must be in Kelvin). V1T1= V2T2 V/T = K V1T2 = V2T1 Gay-Lussacs Law Pressure is directly proportional to temperature if the volume is constant. P1/T1 = P2/T2 5. What is the beau ideal Gas Law in formula form? What is the value for the ratio constant with units? Why are those units so important?b. PV = nRTc. C = PV / T6. Write the balanced equations for CaCO3, BaCO3, Li2CO3, and Na2CO3 reactions with hydrochloric acid. 7. Calculate the molar mass of these same four metallic carbonates. LiCo3 = mass/mole 3.0036g/0.0344 mol = 87.31 g/molMaterials/Equipment* 3.0 M HCl (aq)* 5 ml graduated cylinder* Balloon String* scissors* Weighing paper* 3g of unsung 2 carbonate salt* funnelProceduresFirst measure out 5ml of 3.0 M HCl into the graduated cylinder and beseech 3 g of the unknown carbonate salt. Using the funnel, pour the unknown carbonate salt into the expand and put the open end of the balloon over the graduated cylinder and secure with a string. It is important to dissemble sure the string is very tight to prevent the gas from leaking. overturn the contents of the balloon into the graduated cylinder that contains the 3.0 M HCl. After the gas fills the balloon, use a string and measure the circumfere nce of the balloon. ObservationsCarbonate is constricting reactant.ConclusionBased upon our experiment, equations, and calculations that our unknown Carbonate Salt for Unknown D was Li2CO3 Lithium Carbonate. There could be a number of factors that could have caused us to receive an 18.1% error. How we held the balloon when tipping it over the acid could greatly affect the gas constant of our balloon.
