In this chemical reaction, one can see that when putting the bath bomb in the water, it creates fizz. Bath bombs are made up of several ingredients, but in simplest terms, there are two ingredients that cause this specific chemical reaction. These two ingredients are, citric acid and soda bicarbonate. When the bath bomb is released into the water, the ingredients and water form fizz. The basic chemistry formula to form fizz in the experiment is: Acid + Alkali = Water = Fizz

When putting bacon onto a pan, one can only smell the amazing mouthwatering aroma the chemical reaction creates. When the bacon is put on the pan, it goes through the Maillard Reaction, which is what causes food to turn brown and get flavor. The reaction thus lead the sugars to react with the amino acids.The sweet bacon aroma has compounds, which are, hydrocarbons and aldehydes. They create numerous bonds, some of which create the sweet smell.

All plants go through photosynthesis. The color of a leaf is made partly by photosynthesis. Throughout all of the seasons there are different compounds that make different colors of leaves. Photosynthesis is a chemical reaction within in the leaf, after this the leaf is hungry for sugars, other compounds feed this craving. For example, in the fall, carotenoids cause the leaves to have orange, yellow, or brown colors. Leaves with good amounts of the carotenoids and anthocyanins (which give a red color) create a nice read leaf. The two mix together to form a red color.

During holidays, many people enjoy watching fireworks. In a firework, charcoal, sulfur, and potassium nitrate erupt into flame after heating. The sulfur and charcoal act as fuels in the reaction, while the potassium nitrate acts as the chemical that combines with oxygen (oxidizing). This proves that once the three compounds /elements are heated, they erupt into a firework!

The candy ZotZ is a candy that contains a sour powder full of malic and tartaric acids mixed with sodium bicarbonate. When the powder of these compounds dissolves in someones mouth, the acids and sodium bicarbonate react with the liquid (saliva or water) to produce carbon dioxide bubbles and fizzing. This reaction shows that the chemicals create a fizz.

When someone opens up a bottle of champagne, they see the fizz that comes out. This fizzing is caused by the release of dissolved carbon dioxide (CO2) into the air. Carbon dioxide is dissolved in water under high pressure, by a process called carbonation. The dissolved carbon dioxide reacts with water to form aqueous carbonic acid (H2CO3). When you open the bottle, the pressure drops, and the carbonic acid breaks down to release carbon dioxide, which fizzes out. Since the reaction is accompanied by the emission of gas, this proves that it is a chemical change.

Every once in awhile, a person sits down to eat an apple, they may leave this apple sitting out without finishing it, when they come back to the apple, it is brown. This is because of a chemical reaction that happens between the air and the iron in the apple cells, forming iron oxides. Also, an enzyme called polyphenol oxidase (present in apple cells) helps make this reaction go faster. The oxidase in the apple, makes the apple turn brown fast.

Pennies and many statues are made out of copper. Over a period of time, copper turns a greenish color because of the chemical reaction it experiences. When the copper reacts with the oxygen in the air, water, and carbon dioxide, the brown color turns green. This chemical reaction is called hydrated copper carbonate.

If someone were to pour glycerol onto potassium permanganate they would see in this experiment that the temperature goes from room temperature to very hot because of the flame that erupts. The potassium permanganate oxidises the glycerol to become carbon dioxide and water. Also, the permanganate reduces its size. The chemical formula is: 14KMnO4 + 4C3H5(OH)3 ----> 7K2CO3 + 7Mn2O3 +5CO2 +16H2O

Many people enjoy drinking coffee with their meals, but what gives coffee its nice smell? The coffee smell is created during the main chemical change, which occurs in the roasting process of the coffee making. Chemicals in coffee beans are taken out during brewing and impact the aroma. Two main factors impact the distinctive scent; the concentration of the compound, and the compound's minimum concentration at which coffee's scent is detectable. The ratio of the compound's concentration affect the aroma. The chemical reaction of coffee occurs in the brewing , where compounds are extracted and create an aroma. This shows that a chemical reaction occurred.

Elephant toothpaste is a very cool reaction that many people enjoy experimenting with or watching online. In this reaction, concentrated hydrogen peroxide is mixed with liquid soap. After, potassium iodine is added to make the hydrogen peroxide decompose faster. The hydrogen peroxide breaks down into oxygen and water. Then, a small amount of hydrogen peroxide creates a large amount of oxygen, the oxygen quickly emerges out of the container. The soapy water traps the oxygen, creating bubbles, and turns into foam. The reaction between the potassium iodine and the hydrogen peroxide proves that a chemical reaction happened.

When mixing sulfuric acid with sugar a very cool reaction happens between the two. Sugar is a carbohydrate, when someone removes the water from the molecule, you're basically left with elemental carbon. This dehydration reaction is a type of elimination reaction, proving that a chemical reaction happened. The reaction creates a smell of burnt sugar. The chemical formula is:
C12H22O11 (sugar) + H2SO4 (sulfuric acid) → 12 C (carbom) + 11 H2O (water) + mixture water and acid

During the winter months, the roads are usually very icy. To solve this problem, people throw salt on the ice to melt the ice. The salt lowers the temperature of the ice. The salt also breaks the bonds between the ice molecules which uses energy to do this and the temperature lowers. This is called an endothermic reaction. This proves that pouring salt on ice is a chemical reaction. The video shows how salt melts ice (in this case, onto peoples skin, ouch)!

When someone dissolves sodium hydroxide in water, the water temperature rises. This is because the sodium hydroxide reacts with the water to create heat. The video includes the chemical formula and how this reaction works.

If someone were to combine sodium chloride and sliver nitrate they would see the outcome is a precipitate. The chemical formula is: AgNO3(aq) + NaCl (aq) --> AgCl (s) + NaNO3 (aq)

During campfires, the main snack eaten is a s'more. When toasting a marshmallow for the s'more. the marshmallow undergoes a chemical reaction to become toasted. The sugar molecules in the marshmallow are being changed into carbon. Also. when toasting marshmallows, the heat causes a chemical reaction producing water molecules which then evaporate, leaving the carbon behind.

Cakes are one of the most popular desserts made. While baking a cake in the oven, the cake experiences different chemical reactions. Heat from the oven helps baking powder produce tiny bubbles of gas, which makes the cake light and fluffy. The heat also causes protein from the eggs to change and make the cake firm. Oil keeps the heat from drying out the cake. These prove that a chemical reaction does happen while baking.
