Abstract Water “hardness” was analyzed in this experiment‚ through the determination of CaCO3 concentration. This was achieved by the titration of an unknown solution using a standardized 0.1M EDTA‚ and addition of Eriochrome Black T to the unknown‚ to indicate the endpoint of the titration. The average concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The

DISCUSSIONS WEEK 1: #1 A group of illegal aliens gather together to protest the ratification of a treaty between the U.S with a country rival to their own home country. The group begins a march on Washington. Does the Constitution promote or prohibit this group’s ability to protest? Which parts of the Constitution are involved? Answers: Every person in the U.S. has the right to engage in a protest. The protest should be done in a peaceful matter. The constitution protects every person regardless

English 1A: Discussion Topics John Berger’s “Ways of Seeing” Topic 1: Berger argues that there are barriers to vision‚ problems in the ways we see or don’t see original works of art‚ problems that can be located in and overcome by strategies of approach. For this topic‚ discuss what‚ as you read Berger‚ gets in the way when we look at paintings‚ and what it is that we might do to overcome the barriers to vision (and to history). Imagine that you are speaking to someone interested in art‚ but someone

Findings Analysis to determine the sex of our case study AFA was done using a physical exam karyotyping and PCR-based sex testing. The results from our physical exams on AFA showed well-developed female external genitalia‚ presence of breasts‚ no menstrual cycle‚ and no facial or chest hair. This led to a conclusion that AFA is a sterile female. The results from the Karyotype Analysis showed presence of 22 pairs of autosomes chromosomes and two X’s revealing that she is female. Lastly the PCR-based

Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore‚ it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However‚ it is often not possible to directly measure the heat energy change of the reactants and products (the system). We can measure the heat change that occurs in the surroundings by monitoring temperature changes. If we conduct a reaction between two substances in aqueous solution‚ then the

From the graph I can clearly see that Distilled water has a much larger concentration of water then the cell sap in the potato tissue. I can make this conclusion because the results show a big increase in weight of the potato piece. Meaning that water has moved from outside the potato into the potato due to Osmosis‚ proving that the distilled water had a higher concentration of water‚ as water moves from a high concentration to a low concentration. I can also see that the glucose
