Gas Laws Lab Essay

IntroductionThe four basic physical properties of a gas sample be pressure, volume, temperature, and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic push button 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 step to the fore into their container and occupy the entire volume available, which means they are free to move near and have large amounts of empty space. In many chemical reactions, gases are produced for example, reactions involving metal carbonates that react with an acid produce gaseous carbon dioxide. ObjectiveTo pose the volume of gas produced from a reaction between a metal carbonate and acid and to determine the identity of an unknown carbonate salt.Pre-Lab Questions1. If you increase the temperature what happens to the upper 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 proportional 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 fixed amount of gas at constant pressure is promptly proportional 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 ensample Gas Law in formula form? What is the value for the proportionality constant with units? Wh y are those units so important?b. PV = nRTc. C = PV / T6. salve 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 unknown 2 carbonate salt* FunnelProceduresFirst measure out 5ml of 3.0 M HCl into the graduated cylinder and weigh 3 g of the unknown carbonate salt. Using the funnel, pour the unknown carbonate salt into the balloon and honk the open end of the balloon over the graduated cylinder and secure with a string. It is important to make sure the string is very tight to hamper the gas from leaking. Empty 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 circumference of the balloon. Observations change is limiting 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 radius of our balloon.
