Gas Laws Lab Essay

IntroductionThe quartet basic physical properties of a spoil sample are pressure, plenty, temperature, and build of jettyes. The volume simply indicates the volume of the container since a bobble will concentrate up all space available to it. The temperature indicates the average kinetic dexterity of the splosh particles. For gases, the temperature must be converted to the grand 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 birth a definite shape of volume. Gases ext rest out into their container and occupy the entire volume available, which means they are forfeit to move around and have large amounts of empty space. In numerous chemical reactions, gases are produced for example, reactions involving metal carbonates that react with an acid produce va shootish carbon dioxide. ObjectiveTo determine the volume of gas produced from a rea ction between a metal carbonate and acid and to determine the identity operator of an unknown carbonate common 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? argon you at standard conditions in the lab? 4. Boyles Law The article of faith that the volume of a given mass of an ideal gas is inversely proportional to its pressure, as long as temperature remains constant. Boyles honor 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 instantly 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 Ideal Gas Law in formula form? W hat is the range for the proportionality constant with units? Why are those units so great?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 homogeneous 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 take in* 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 put 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 prevent the gas from leaking. Empty the contents of the balloon into the graduated cylinder that contains the 3.0 M HCl. later on 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 secret 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 carry on the radius of our balloon.
