What kinds of chemical reactions have you seen around your home? (Think about cooking or grilling.) Explain the evidence you have seen that they are chemical reactions.

When your cooking, or baking a cake. For example, If you bake a cake you are adding ingredients to the cake. When you still the cake into the oven all the ingredients are reacting to each other, causing a chemical reaction.  

Explanation:

Combustion, Rust, Soap and Detergent Reactions, and cooking

Explanation:

Combustion : Every time you strike a match, burn a candle, build a fire, or light a grill, you see the combustion reaction. Combustion combines energetic molecules with oxygen to produce carbon dioxide and water.

For example, the equation for the combustion reaction of propane, found in gas grills and some fireplaces, is:

C3H8 + 5O2 → 4H2O + 3CO2 + energy

Rust : Over time, iron develops a red, flaky coating called rust. This is an example of an oxidation reaction. Other everyday examples include formation of verdigris on copper and tarnishing of silver.

Here is the chemical equation for the rusting of iron:

Fe + O2 + H2O → Fe2O3. XH2O

Soap and Detergent Reactions : Soaps and detergents clean by way of chemical reactions. Soap emulsifies grime, which means oily stains bind to the soap so they can be lifted away with water. Detergents act as surfactants, lowering the surface tension of water so it can interact with oils, isolate them, and rinse them away.

Cooking : Cooking uses heat to cause chemical changes in food. For example, when you hard boil an egg, the hydrogen sulfide produced by heating the egg white can react with iron from the egg yolk to form a grayish-green ring around the yolk. When you brown meat or baked goods, the Maillard reaction between amino acids and sugars produces a brown color and a desirable flavor.

Hope this helped you, Good luck! :))
