The purpose of the first experiment was to practice obtaining accurate and precise results by doing combustion analysis to find the amount of carbon dioxide and water released and the amount of fuel consumed. To identify the amount of carbon dioxide, water and burner consumed there were three equations used to find it. Equation 1 shows how much carbon dioxide was released.
Mass of carbon dioxide = m2 - m1
Equation 1 was used as an experimental procedure created to help find out the amount of carbon dioxide.
To find how much water was released can be seen in Equation 2. Mass of water= m2 - m1
Like Equation 1, Equation 2 was also created to help find the amount of water released. To find the m2 in Equation 1 and Equation 2 it can be found as seen in Equation 3. m2= experiment weight- blank weight To find the m1 in Equation 1 and Equation 2 it can be seen in Equation 4. m1= blank weight- before weight
To find the amount that the burner consumed it can be seen in Equation 5.
Mass of burner= before weight- experiment weight
It is important to be able to understand how to do these equations because by knowing how to do them it can be applied to use in the second experiment. The purpose of the second experiment was to use the procedure practiced in the first experiment to identify what the unknown given is. By knowing how to find the identity of an unknown in experiment two, it can later be applied when a problem arises that there is a need to find an identity of an unknown.
Experimental:
For the first experiment, a funnel, carbon dioxide trap, water trap, a burner and connecters were obtained to make a combustion apparatus. The two traps were made by the teacher assistant for the first trial. The two traps and the burner were weighed and recorded. One end of the water trap was then attached to the funnel then a connector was attached to the other end of the water trap and one end of the carbon dioxide trap. The other end of the carbon
