The picture shows iron that has orange rust on it as a result of oxidation. The chemical equation for the rusting of iron is 4Fe + 3O2 → 2Fe2O3. The reactants are iron and oxygen and it produces a new substance which is rust and is also the product of the chemical reaction. The original silver or gray metal color turns to a brown orange which is from the rust.]]> 2019-02-26 17:09:25 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335478359 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335966961 When you buy milk from the store, it is a white liquid that is good for your bones. If the milk is left for too long, it changes. It gets expired. It probably will begin to smell. This is a chemical change. What happens to the milk produces a new substance which is its aroma. It has a terrible smell produced. The chemical equation for this reaction is C12H22O11+ H2O= 4C3H6O. The reactants are milk and air and the product is sour milk.]]> 2019-02-27 16:09:01 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335966961 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335971930 When sugar heats, it melts into a liquidy substance that is brown. The original sugar substance is white. This is a color change and a chemical reaction. The liquidy sugar substance is a newly formed substance. The reactants are sugar and fire and the product is caramel. C₁₂H₂₂O₁₁ and fire make the product. ]]> 2019-02-27 16:16:03 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335971930 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335973300 The reaction between vinegar and baking soda causes gas bubbles to form which makes the mixture fizz. The reactants are vinegar and baking soda. The chemical equation is CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O.]]> 2019-02-27 16:18:02 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/335973300 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336423668
The inside of an egg shell is somewhat liquidy. There is a clear sticky substance with a yellow center. When heat is applied, the egg becomes a solid. The outer liquid turns white and becomes solid. This solid is the new substance that is created in the chemical reaction. The reactants are raw egg and fire and the product is cooked egg. ]]> 2019-02-28 14:54:49 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336423668 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336423721
Brownie batter is a liquid made from many different ingredients. Many of the dry ingredients like flour, allow the batter to turn into a solid bread-like substance when it is heated up. This is the new substance that is formed. The reactants are brownie batter and heat. The product is baked brownies.]]> 2019-02-28 14:54:53 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336423721 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336664224 The ammonium chloride, when mixed with water, absorbs heat and leaves the water cooler than before. This reaction is endothermic because it absorbed heat instead of releasing it. The reactants are water and ammonium chloride.

The reactants in this experiment is potassium iodide and hydrogen peroxide (6%).  The container this experiment occurs in should feel warm because of the heat that was released. The new substance created is a foam that is so giant it looks like a form of toothpaste that an elephant could use.

Chemical reactions with plants occur everyday through photosynthesis. Plants convert carbon dioxide and water into glucose and oxygen. This gives them food to grow as well as the animals around them. The new substance produced is oxygen and glucose. The reactants are plants and water/carbon dioxide. The chemical equation for this is 6 CO₂ + 6 H₂O + light → C​₆H₁₂O₆ + 6 O₂]]> 2019-02-28 22:26:49 UTC https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336671127 sydneyban2023 https://padlet.com/sydneyban2023/collagerichardsonp4/wish/336672101 To light a match, the match and match box are striked together creating friction. This produces a tiny flame on the match. The molecules are combined with oxygen. This produces carbon dioxide and water. The reactants are oxygen and molecules and the product is carbon dioxide that is produced from the flame.
