He illustrates the dangers of dust explosions and shows that he has a deep understanding of this subject. ]]> 2018-02-24 03:51:43 UTC https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946556 Significant Facts gkurtenbach20 https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946561 1. Sugar (Sucrose- C12 H22 O11) produces large amounts of energy when it burns. 
2. The increase in volume increase during a chemical reaction is what causes explosions, not the reaction itself. 
3. The sugar combustion reaction increases the number of gas molecules from 12 to 23. 
4. A larger surface area causes solids to combust more and faster. 
5. In 30 years, more than 350 explosions have occurred and 130  people have died from them.

2. How dangerous are most of the explosions if 10% of the fatalities are from 1 out of 350 explosions? 
3. Why do chemical reactions release heat? 
4. Do other explosives operate with the same idea of creating more gas molecules in a condensed space? 
5. Can the same effect be created with all molecules?

This relates back to our chemistry class, because we are learning about different types of reactions and the outcomes that they produce. ]]> 2018-02-24 03:52:27 UTC https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946591 Why do chemical reactions release heat? gkurtenbach20 https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946616 Some chemical reactions are called exothermic reactions. These reactions require less energy to start than they produce. The extra energy that is produced is released as heat which is sometimes enough to start another reaction starting a chain reaction of exothermic reactions. This is what happened in the article. A little bit of sugar caught and it started a chain reaction throughout the entire building.]]> 2018-02-24 03:53:00 UTC https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946616 Do other explosives operate with the same idea of creating more gas molecules in a condensed space? gkurtenbach20 https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946630 Normal explosives that you would imagine work under the same principle. Solids form into a large number of gases, so quickly that causes an explosion. This explosion is the rapid expansion of gas and extra energy from the reactants. If the expansion is faster than the speed of light then it will create a shock wave. ]]> 2018-02-24 03:53:14 UTC https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946630 Can the same effect as the sucrose combustion be created with all chemical reactions? gkurtenbach20 https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946645 No, the same effect can not be created with all molecules. Heat is just the random movement of molecules, and when to much heat is applied and there is to much movement. The molecules lose the ability to hold themselves together and they react to each other. Some reactions are exothermic which release more energy than they use, and some reactions are endothermic which use more energy than they release. Exothermic reactions will release heat as energy, but endothermic reactions will actually take in heat. Obviously, endothermic reactions do not have the same effect as sucrose combustion. ]]> 2018-02-24 03:53:31 UTC https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234946645 gkurtenbach20 https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234947376 2018-02-24 04:09:26 UTC https://padlet.com/gkurtenbach20/dmn6w8wrptsj/wish/234947376
