This produces the fizz, or bubbles which is truly just the carbon dioxide gas being released.]]> 2016-02-19 20:32:06 UTC https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96191303 jarettfersten20 https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96191390 Rusting is the breakdown of the metal iron. The reactants of this chemical reaction are iron, water, and oxygen, and the product is iron oxide, better known as rust. Rust, unlike iron, is crumbly and orange. The nail was originally silver but after rusting it is now orange. ]]> 2016-02-19 20:32:43 UTC https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96191390 jarettfersten20 https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96192161 When the wood reaches a certain degree, the heat decomposes some of the material that makes up the wood. Some of the decomposed material is released as volatile gases, or smoke.The rest of the material forms char, which is all of the unburnable minerals in the wood.

This is because when an apple is either plucked or has a wound, it causes the production of new enzymes that act on the chemicals present in the fruit. This then causes the apple begins to emit an aroma. ]]> 2016-02-19 20:44:19 UTC https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96193416 jarettfersten20 https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96194414 An instant cold pack is an ice pack that is made of two bags; a bag containing water, which is inside a bag containing ammonium nitrate, calcium ammonium nitrate or urea. When the inner bag of water is broken by squeezing the package, it is allowed to dissolve the solid in an endothermic reaction. This reaction absorbs heat from the surroundings, quickly lowering the pack's temperature.]]> 2016-02-19 20:50:36 UTC https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96194414 jarettfersten20 https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96194682 Lead nitrate solution contains particles of lead and potassium iodide contains particles of iodide.

This process is called abscission. With less water, photosynthesis stops, and so does the integration of chlorophyll, one of the pigments in leaves. This then causes the leaf to take the color of the other pigments in the leaf, carotene and anthocyanins (yellow and red) and then we see a change in color.

This is when hydrogen peroxide, dish soap, and a yeast water solution are combined. The yeast contains an enzyme that breaks down the hydrogen peroxide into oxygen, gas, and water. The oxygen gets trapped by the soap, and as a result a large foamy solution is created. ]]> 2016-02-21 17:05:36 UTC https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96279577 jarettfersten20 https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96280085 2016-02-21 17:14:28 UTC https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96280085 jarettfersten20 https://padlet.com/jarettfersten20/xigo1a7jpsoi/wish/96281013 Milk becoming sour is a chemical change because once it is left out in room temperature bacteria forms in the milk, and it becomes sour.
