Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

C-O-C bond angle is 111o‚ slightly higher than the H-O-H bond angle in water because of the stronger electron repulsion between the bulky alkyl groups. Preparation of Ethers: 1. Preparation of symmetrical ethers from alcohols H2SO4 R O R + H2O 2ROH 2. Williamson Ether Synthesis R O Na - - + + + R’X R O R’ + NaX Ar O Na + RX Ar O R + NaX Involves a nucleophilic substitution reaction. Halide ion is displaced by the alkoxide or phenoxide ion.

The Separation of Powers exists to protect the natural rights of the people. It was created by Baron de Montesquieu during the Enlightenment and used in the Declaration of Independence by the Framers. The Separation of Powers is a division of government into three branches which prevents one branch from gaining too much power. The Separation of Powers‚ used by the Founding Fathers‚ is just as important today as when the written. The Separation of Powers is a system of Checks and Balances that acts

Acid-Base Strengths of Organic Compounds By: Chris Frankmore Due Date: February 15‚ 2011 Resonance Benzenesulfonic Acid Benzoic Acid Benzyl Alcohol Benzylamine P-Cresol P-Toluidine Acid/Base | Structure | pH | Why It is a strong/weak acid/base | Benzenesulfonic Acid | | 1 | This is a strong acid because it has a pH of 1. Another reason why this is a strong acid is that its conjugate base has strong resonance stabilization

According to the hypothesis of Baltes and his colleagues there are five components of wise judgment consisting of factual knowledge about matters of life‚ procedural knowledge‚ lifespan contextualism‚ recognition and management of uncertainty and relativism regarding solutions. An example situation is one that a mother knows her seven year old child has stolen has stolen a box of cookies from the store while she was shopping. In this situation the mother is well aware of the factual knowledge that

Conclusion and Evaluation Conclusion In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water‚ one was 5% sugar‚ one 10%‚ one 15%‚ one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution. To keep the experiment fair we only changed one variable which was the salt concentration. The results that we got showed the chip went up in mass for 0%

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest
