The Bubble Bursts essays Have one ever-wondered why and how the stock market crashed? What happened in the 1930s will never be forgotten. It was a time of turmoil for our country. Many people became unemployed. Some people blamed it on the president, Herbert Hoover. They said that he shouldve seen it coming. One can learn more if one should read on. The Stock Market Crash of 1929 sparked the Great Depression. It threw thousands of Americans out of jobs and ruined many families. It was a horrible time in history for the lives of many Americans. The Stock Market Crash was a time when millions of stocks prices fell and thousands of Americans were out of money. The aftermath of this event was very bad. It left thousands of people out of job and many lost their homes and some went to the extreme, committing suicide. Over production was one of the causes of the depression. Although it wasnt the only cause, it made a big impact. Stores and companies had so many products left over by the war that they needed to sell them. When they wouldnt sell they lowered the prices. They ended up lowering them to very little money and werent making a profit. Another cause of the depression was weak banking system. Banks had made loans to people in the stock market. When the stock market crashed however, people couldnt pay back the loans. Without the money, banks couldnt pay other people. Many banks were forced to close. The US had made loans to Europe.

It all lead to worldwide economical collapse. During the depression, unemployment soared. Unemployment is where people are fired from their jobs. There wasnt anywhere for the people to work. Some people sold apples, which others sold newspapers or other random th ...

The Chemistry Behind How Febreze Works

The Chemistry Behind How Febreze Works Does Febreze remove odors or merely mask them? Heres the chemistry behind how Febreze works, including information about its active ingredient, cyclodextrin, and how the product interacts with odors. Febreze was invented by Procter Gamble and introduced in 1996. The active ingredient in Febreze is beta-cyclodextrin, a carbohydrate. Beta-cyclodextrin is an 8-sugar ringed molecule that is formed via an enzymatic conversion of starch, usually from corn. How Febreze Works The cyclodextrin molecule resembles a doughnut. When you spray Febreze, the water in the product partially dissolves the odor, allowing it to form a complex inside the hole of the cyclodextrin doughnut shape. The stink molecule is still there, but it cant bind to your odor receptors, so you cant smell it. Depending on the type of Febreze youre using, the odor might simply be deactivated or it might be replaced with something nice-smelling, such as a fruity or floral fragrance. As Febreze dries, more and more of the odor molecules bind to the cyclodextrin, lowering the concentration of the molecules in the air and eliminating the odor. If water is added once again, the odor molecules are released, allowing them to be washed away and truly removed. Some sources say that Febreze also contains zinc chloride, which would help to neutralize sulfur-containing odors (e.g., onions, rotten eggs) and might dull nasal receptor sensitivity to smell, but this compound is not listed in the ingredients, at least in the spray-on products.
