The concept of Freedom of speech is one which is held sovereign by many constitutions and individuals‚ especially within the American states. The idea of limiting an American citizen’s freedom of speech would be highly offensive and seen as an act only a dictatorial Government would undertake which‚ with many factors considered‚ is true. The actions that in many cases are considered by these Governments are;

Using Stoichiometry to Determine Gases Produced in a Reaction Introduction Magnesium is a metal and is the third most commonly used metal by chemists. Some would say it is the least dense structural metal. Its lightness is often alloyed with aluminum. Magnesium is also used in racing car wheels called MAG wheels. Many car-manufacturing companies will use magnesium and aluminum because of the lightness of the metal. Both of these metals are reactive with acids. The most common acid in they

Stoichiometry Practice Problems Be sure to balance all equations before you start calculating! Answer key is at the end. 1) Lithium hydroxide reacts with hydrobromic acid to produce lithium bromide and water. If you start with ten grams of lithium hydroxide‚ how many grams of lithium bromide will be produced? 2) Ethylene (C2H4 ) reacts with oxygen gas to produce carbon dioxide and water. If you start with 45 grams of ethylene‚ how many grams of carbon dioxide will be produced?

Limiting Homework English 101 Stundents Under Stress In the article “Students under Stress” author Marcia Clemmitt points out that students who are undergoing stress in school is because of the increase of homework. Too much homework is causing an increase of problems for students. The increase of homework is causing students to be depressed‚ stressed‚ and pressured unnecessarily‚ especially for students at young ages causing them to have a negative view of school. The amount of homework

Investigating Stoichiometry with Carbonic Acid Salts Problem: Testing the actual yield versus the theoretical yield of NaCl when HCl is titrated into Na2CO3 and NaHCO3. When 0.15g of both NaHCO3 and Na2CO3 are titrated with HCl‚ then 0.165g of NaCl should form from the NaHCO3‚ and 0.104g of NaCl should form from the 0.15g of Na2CO3. Procedure: Weigh 2 samples of 0.15g of dried unknown each‚ and dissolve each into 50mL of distilled water. Add 0.5 to 1mL of bromocresol green indicator until the

Fewer than one percent of people who are exposed to alcohol in the U.S have required medical attention due to consumption. Some people argue that strict laws on alcohol are needed to prevent people from endangering themselves or others‚ however if we taught moderation and responsibility at an early age we could still enjoy the benefits of drinking in a more controlled environment. The laws that focus on drinking need to be formed to include all of the teaching moments and benefits that go along with

Lab #3: Stoichiometry of a Precipitation Reaction October 14‚ 2014 Abstract: The purpose of the lab‚ Stoichiometry of a Precipitation Reaction‚ is to be able to calculate the amount of a second reactant we need to react with the reactant one. You must calculate the amount of the second reactant using stoichiometry to figure out what amount is needed. After the amount is calculated‚ you then can add it to the first reactant and it will give you a full reaction. To figure out what you

ETHERS Classification of Ethers: Symmetrical ethers – two groups attached to O are identical Ex. CH3CH2OCH2CH3 – diethyl ether Unsymmetrical ethers – two groups attached to O are not identical Ex. CH3CH2OCH3 – ethyl methyl ether Physical Properties of Ethers: Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the

Limiting Immigration Would you reject or support David Miller’s grounds for limiting immigration? In his 2005 “Immigration: The Case of Limits” paper‚ David Miller argues in favor of the right for countries to limit immigration. He replies to defenders of open borders and gives conditions for morally acceptable immigration policies. Most importantly‚ he offers two reasons for nation-states to limit the flux of incoming long-term residents (refugees are thus not part of our discussion) to their
