In the Mass and Mole Relationships in a Chemical Reaction lab, our goal was to investigate mass and mole relationships between the reactants and products of a chemical reaction. Our hypothesis was that if there is a 1:1 mole ratio between a product and reactant, then the given number of moles will produce the same number of moles of the product. This hypothesis was proven false because at the end of the reaction, less than 1 mole of sodium was produced. The second hypothesis was that if a chemical reaction occurs, then there is a chance that the reaction will produce less than the expected amount. Our results showed that this hypothesis was true because we predicted that the mass of the salt would be 1.41 grams but the actual mass was 1.33 …show more content…
The actual yield was 1.41 grams. The percent yield is defined as the accuracy of the chemical reaction. To find it, divide the experimental mass with the theoretical mass and multiply the number by 100. The percent yield of this was 94.33%, meaning the experiment was about 94.33% accurate. However, one of the flaws in this process is that the beaker was heated too quickly which caused the contents to overheat, leaving no sodium. To fix this mistake, we could have made the flame from the bunsen burner smaller which might allow the beaker to heat at a normal pace. One of our solutions was borrowing lab data from another group. A question I was left with after the lab was, if the beaker being heated too fast was not the problem that messed up our reaction, what else could have caused the chemical reaction to go wrong? Also, will there ever be an instance where one of the hypotheses is true and with a 1:1 ratio, the given number of moles of reactants will produce the same number in the product? All in all, I learned that when mixed together and heated, sodium bicarbonate, also known as baking soda, and hydrochloric acid can create

Enthalpy Lab Report Essay

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice, once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:…

and adding iron sulfate and copper will be used in a single replacement action. Also it should be able to find the ratio of moles of a reactant to moles of a product in the chemical reaction. Thus, it should answer another purpose for the lab which is to find is to be able to relate this ratio to the coefficients of these substances in the balanced equation for the reaction. Hypothesis: Both of coefficient off iron Variables: Procedure Find the mass of a clean, dry 100 ml beaker. Record the mass…

Heat Of Reaction Lab Essay

Chem 1212 Lab report Heat of Reaction In this experiment, we explore the fundamental rules of heat in reactions. We notice how heat flows from hotter to colder systems, we determine the heats of reactions and we test the difference or visualize the difference between exothermic and endothermic heat reactions. This goes hand in hand with our previous experiment, the specific heat lab. We are reminded to wear out safety glasses at all times, of course; as is the case with every lab we carry…

Synthesis of Co(Acac)3 Essay

Amanda Tran Date of lab: 04/25/05 Date submitted: 05/09/05 Chem 2130-3 Experiment 3: Synthesis of Co(acac-NO2)3 Introduction In this lab, Co(acac·NO2)3 is synthesized using the Co(acac)3 complex produced in Experiment 2. The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3, Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product…

Exergonic Reaction Lab

Background The cell is filled with a myriad of chemical reactions happening simultaneously that work to ensure its survival. Some of these reactions are exergonic, meaning they release energy and occur spontaneously. They occur spontaneously because the products of the reaction have a lower free energy than the reactants. The free energy of a reaction is how much of the energy in the reaction's system is free to do work. When the reaction occurs, the free energy that was stored in the reactants…
