If any of these things seem to be happening, you know a chemical reaction is occurring.]]> 2016-02-18 19:42:25 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/95956792 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/95957374 This image depicts a beaker of fizzing liquid. The bubbles show that gases are forming meaning that new substances are being created. New substances mean that it is a chemical reaction taking place.
Alka-Seltzer
Like what we used in the lab, when placed in water the tablet fizzes and dissolves.]]> 2016-02-18 19:44:04 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/95957374 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/95958816 Simple things like burning logs, or firewood can create different aromas. The oils on the logs and the actual wood it is made of burns and provides the "fuel" for the fuel, air, and oxygen combo to make a flame.]]> 2016-02-18 19:48:13 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/95958816 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/95960040 This letter is about how when chemical reactions occur, there are sometimes changes in the color of the liquid or solvent that was mixed with the solute. Color changes can vary. Sometimes chemiluminescence makes the solution glow in the dark.]]> 2016-02-18 19:52:10 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/95960040 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96169588 When the two solutions are combined there is a big fizz that happens. The bubbles get pushed upward and a chemical reaction occurs due to the gas created.]]> 2016-02-19 19:07:12 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96169588 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96169703 When metals or other materials are left in water, or corrode, they get rusty, the rust is normally a different color than the original material is.]]> 2016-02-19 19:07:41 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96169703 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96169817 Some candles are made to give off sents. These candles are artificial, but the reaction that occurs with the wax it is made of and the heat of the flame makes the distinct aroma.]]> 2016-02-19 19:08:11 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96169817 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96171698 When chemical reactions occur, the temperature of a liquid or solid can change. It can become colder or hotter depending on the type of reaction that occurred.
Liquid Nitrogen:
It can make objects,gases, and liquids frozen within minutes.]]> 2016-02-19 19:14:15 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96171698 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96172963 Heat is generated in the reaction that occurs within the reactor. (Uranium fuel rods). The system can overheat if the water cooling does not support it.]]> 2016-02-19 19:19:03 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96172963 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96173477 This part signifies that when reactions occur sometimes the substances become solids when they start off as not. 
Freezing Water:
When water is cooled, the molecules can lose neergy and solidify into ice. Waters solid form.]]> 2016-02-19 19:20:41 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96173477 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96175093 In the lab we did in class at the beginning of the year, we mixed together ingredients, mostly liquids, and after the reaction occurred the mixture turned into a solid gooey mass of putty.]]> 2016-02-19 19:25:48 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96175093 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96175948 The one thing that marks a chemical reaction is when a new substance is formed. The reaction can create new gases, liquids, or solids.
Formation of Table Salt:
Chlorine gas, and sodium metal combines creates a brand new substance, table salt.]]> 2016-02-19 19:28:40 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96175948 graysonclark202 https://padlet.com/graysonclark202/p0i8wien53n0/wish/96178437 When ice and hot water combine a reaction occurs that melts the ice and creates steam, a byproduct of the reaction. The reaction occurs because of the cold ice and hot water counteracting each others temperatures.]]> 2016-02-19 19:37:40 UTC https://padlet.com/graysonclark202/p0i8wien53n0/wish/96178437
