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

Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction: The student will perform the experiment in order to find the percent yield by using the theoretical value found using the balanced equation for sodium carbonate as well as sodium bicarbonate. The objective is to stabilize the substances by titrations and finding the percent yield when all the data is collected. The purpose of this procedure is so that the student will get better understanding of stoichiometry. The student

The article‚ “Limiting Democracy: The American Media’s World View‚ and Ours‚” written by Glenn Greenwald presents that fallacious facts have been conferred by the media as a whole which leads to political bias that was built upon misquoted or manipulated truth. Greenwald wrote‚ “One of the difficulties in discussing the notion that it is the media that limits our idea of politics is that we all have an inherent resistance to believing that our own understanding of the political world is artificially

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

A student takes a sample of KOH stock solution and dilutes it with 100.0 mLof water. The student determines that the diluted solution is 0.046 M KOH‚ but has forgotten to record the volume of the original stock solution sample. The concentration of the stock solution is 2.09 M.

The leaders of the political parties of the Canadian House of Commons ‚ with the assistance of ’whips’‚ very strongly discipline their party members to vote on issues as a single entity‚ especially in plenary sessions (Olson‚ 2003). Although‚ some degree of party discipline is essential for any political

Head injuries can take students out of the game for the rest of their lives‚ and make their lives different forever. Concussions are a big problem with sports today‚ but so is the amount of pressure put on these student athletes. limiting sports can help athletes by limiting the pressure put on them.

Introduction The objective of this lab was to show how stoichiometry is applied to a specific chemical reaction. Stoichiometry is pretty much the math behind chemistry. Doing stoichiometry can calculate masses‚ moles‚ and percents with a chemical equation. The use of stoichiometry is how we were able to find the limiting reagent in this lab. A limiting reagent is the chemical that will be used up first. Many calculations had to be made throughout this lab. Some of the calculations we made were
