Potassium Permanganate + Sugar and Caustic Solution

# data[].attributes.body
In this video, potassium permanganate is put into a beaker of sugar and caustic solution. The mixture is then mixed using magnetic stirrer until the mixture has chemically combined.

KMnO4 (purple) + C6H12O6 (sugar) + NaOH (caustic) → K2MnO4

The chemical change that occurs through the change in color of this reaction means that a chemical reaction happened. This reaction happens because the permanganate ion loses an electron.

In this video, There is cake batter put in the oven and baked as a liquid. When the cake comes out of the oven it is a new solid with a new smell or aroma.

2NaHCO3 → Na2CO3 + H2O + CO2

This is a chemical change because when the cake is baking the baking soda after being heated releases C02 that makes the cake rise. This is an endothermic reaction in which the cake batter is absorbing the heat from around it in order to create the baked cake. As the cake is baked the smell changes and it is a different and stronger scent then before.

In the video between two glasses, hydrogen peroxide, potassium iodide, sodium thiosulfate, starch, and an acid were mixed together. ONe they are mixed together the color changes.

H2O2 (aq) + 2 I- (aq) + 2 H+ (aq) → I2 (aq) + 2 H2O (l)

This reaction works because the substances the produce iodine mixed with the starch and the reaction causes a color change. This color is the sign that a chemical change has occurred and a new substance has been produced.

In this video the wood is being burnt in the form of a fire and smoke is being let off.

C6H10O5 + 6O2 → 6CO2 + 5H2O + Heat.

THis reaction takes place when wood reacts with oxygen. The result of this combination is a chemical change that is scene in the form of an effervescence.

In this video a cup of milk is left out for hours and it turns sour. This reaction creates a new substance. This new substance will also have a new or different smell the kit had at the beginning. Because of this change in aroma and creation of a new substance, this is a chemical reaction.

C12H22O11 (lactose) + H2O → 4C3H6O3 (lactic acid

In this video we see the original small mixture as it enters the sky and turns into a colorful firework. This little mixture creates an entirely new substance when all of its components are mixed and then launched into the sky. This is a chemical reaction because of its creation of a new substance.

6KNO3 + C7H4O + 2S → K2CO3 + K2SO4 + K2S + 4CO2 + 2CO + 2H2O + 3N2

In this video there is a beaker of hydrogen peroxide. In this beaker there is then yewats added. This combination created a chemical reaction. We know that this chemical reaction took place because of the foam and effervescence that happened as a result of the chemical reaction showing the chemical change.

2H2O2 → 2H2O + O2

In this video a temperature is recorded of the calcium hydroxide. The water is added to the calcium hydroxide and left to sit. Once the temperature is recorded again it is noticed that there is a big temperature change.

Ca(OH)2 (s) + H2O (l) → Ca(OH)2 (aq

During the process of this reaction there is a very large about of heat that is released. This is because of the very intense reaction. The drastic temperature change indicates that there is a chemical change happening.

In this video pancake batter is added to a pan on the stove and fried. This creates a new substance.

NaHCO₃ (baking soda) + H+ (acid) → CO₂ (carbon dioxide) + H₂O (water) + Na+ (sodium ion)

When pancakes are being cooked the baking soda and whatever acid is incid creates CO2. The CO2 then becomes trapped in the batter that helps the pancakes rise. The substance has then changed from the pancake batter to a cooked pancake as a result of this chemical change.

In this reaction these two substances were added together. As a result of these being added together a precipitate was formed. The Silver chloride was the part that created the precipitate. The precipitate was how we know a chemical change occured.

KCl (aq) + AgNO3 (aq) → AgCl (s) + KNO3 (aq)
