2nd period Chemical and corporeal Changes Lab Purpose: Experiment each(prenominal)y deem the limiting reactant in chemical reaction. Materials/Safety: HCLGlassesScoopula footrace undergroundsTest pipework rackBaking powder BaloonsBalance cognitive operation: jump add 2.0 M HCL to the mental trial runing organ pipes. whence we designate individually of three ballons as A,B,C and weighed them. accordingly weighed 3 portions of baking hot savory pop music as it was shown in table column. Then we laid ballons and reweighed them to know faultless draw of baking dad in ballons. Then we cautiously placed ballons on test supply without spilling any of baking soda into flask. After that we displace the fly so all solid went into liquid. When the reaction was complete, we carefully distant wallow, tied complete and weighed. Then subtracted the mass of the ballon to get mass of assail produced. data/Results: HCL in subwayBaking soda in BalloonActual mass of NaHCO3Mass ofGas producedObservation organ pipe 112ml1.3 g1.13g1.

The tube with more than chemical ever so gave more mass. The gas that alter the balloon was CO2. Error summary: Forgot to weigh ballon with Baking pulverisation in test tube 2 so had to total it. Comments: I did not want this lab because it had a parcel out of calculations included.If you involve to get a full essay, order it on our website: Ordercustompaper.com
