Glow sticks cracking

charleebaker2029 — 2025-02-27 14:29:25 UTC

When you take a glow stick in your hands, and forcefully crack it, a chemical change occurs. Breaking the glass vial inside the stick, allows two separate chemicals to mix, triggering a chemical reaction that produces light. This is through a process called chemiluminescence (new bonds forming causing the glow).

Chemical Equation: H2O2 + C8H8O4 -> H2O + CO2

Reactants and Products:

Reactants:

diphenyl oxalate (plastic tube)
hydrogen peroxide (glass vial)

Products:

light
color (depends on dye)

This is also an example of a new substance being made (cant be reversed).

Sodium Bicarbonate and Lemon Juice

charleebaker2029 — 2025-02-27 14:29:46 UTC

In the lemon fizz experiment, you add a small amount of baking soda (sodium bicarbonate) to a glass, then quickly add some lemon juice. It will then fizz due to a chemical reaction between the acidic lemon juice and the basic baking soda. The causes carbon dioxide gas to release which creates bubbles.

Chemical Equation: NaHCO3 + C6H8O7 --> Na3C6H5O7 + H2O + CO2

Reactants and Products:

Reactants:

Lemon Juice
Baking Soda

Products:

Carbon Dioxide Gas
Water
Sodium Carbonate

This is also an example of a new substance being made (cant be reversed).

Iron Chloride and Sodium Hydroxide

charleebaker2029 — 2025-02-27 23:09:27 UTC

When mixing iron chloride and sodium hydroxide solutions, you can observe the formation of a solid precipitate, indicating a chemical reaction occurred. In the reaction, they drop a few drops of sodium hydroxide and just as it touches the other substance, it turns into a precipitate (when two liquids make a solid).

Chemical Reaction: FeCl3 (aq) + 3NaOH (aq) → Fe(OH)3 (s) + 3NaCl (aq).

Reactants and Products:

Reactants:

Iron Chloride
Sodium Hydrochloric

Products:

Salt
Iron

This is also an example of a new substance being made (cant be reversed).

Barium Chloride and Sodium Sulfate

charleebaker2029 — 2025-02-27 23:09:51 UTC

When barium chloride combines with sodium sulfate a white precipitate of barium sulfate is formed which is insoluble in water meaning it wont be able to dissolve. When a precipitate is created out of too liquids, it is a good indicator that a chemical reaction has occurred.

Chemical Equation: BaCl2 + Na2SO4 → BaSO4 + 2NaCl

Reactants and Products:

Reactants:

Barium Chloride
Sodium Sulfate

Products:

Barium Sulfate (a white precipitate)
Sodium Chloride (NaCl)

This is also an example of a new substance being made (cant be reversed).

Apple Rotting

charleebaker2029 — 2025-03-03 00:30:21 UTC

If you were to leave a piece of apple, a cake you made, oranges, etc, out for too long, it would cause it to rot and smell bad. If we take an apple for example, sit it out for a month and come back to it, it would have an oxidation reaction. This means that it would involve the transfer of electrons from one species to another. Having all of this happen, the smell of the apple in the beginnings to the end would change a tremendous amount. At first it would smell sweet and ripe but after the change occurred, they would smell sharp, tangy, and vinegar-like.

Chemical Equation: C6H12O6 + O2 -> C6H10O5 + H2O

Reactants and Products:

Reactants:

Apple
Oxygen
Light

Products:

Decayed/Rotten apple

This is also an example of a color change and a new substance (cant be reversed).

Alka-Seltzer tablets dissolving in water

charleebaker2029 — 2025-03-03 00:42:25 UTC

If you take a store bought seltzer tablet and inserted it into some water, a chemical change would occur. Carbon dioxide gas is formed as a result of a reaction between the tablet's components and water. This is evident by the visible fizzing and bubbles produced.

Chemical Equation: NaHCO3 + C6H8O7 + H2O → Na3C6H5O7 + CO2 + H2O

Reactants and Products:

Reactants:

Tablet
Water

Products:

Carbon Dioxide Gas
New substance (tablet in water)

This is also an example of a new substance being made (cant be reversed).

Baking a cake

charleebaker2029 — 2025-03-03 00:51:16 UTC

When you bake a cake, it is a chemical reaction because all the ingredients getting together form a new substance. Baking soda reacts with other ingredients to create carbon dioxide gas bubbles that make the cake rise. The structure of the batter changes aking with irreversible reactions being produced.

Chemical Reaction: Ingredients mix before baking; after baking, they transform into a solid cake due to heat and chemical reactions.

Reactants and Products:

Reactants:

Sugar
Butter
Eggs
Vanilla extract
Flour
Baking powder
Milk

Products:

Carbon Dioxide Gas
Cake

This is also somewhat an example of fizz because it does release carbon dioxide gas, a new substance being made (cant be reversed), and a color change.

Potassium Permanganate and Sodium Bisulfite

charleebaker2029 — 2025-03-03 02:43:12 UTC

In this experiment, the Potassium Permanganate (the purple solution) is in a jar and then the sodium bisulfite (a powder) is added. Nothing happens at first and then when swirled, the color completely changed, an indicator of a chemical reaction.

Chemical Equation: 2KMnO4 + 5Na2SO3 + 3H2SO4 → K2SO4 + 2MnSO4 + 5Na2SO4 + 3H2O

Reactants and Products:

Reactants:

Potassium Permanganate
Sodium Bisulfite

Products:

sodium sulfate

This is also an example of a new substance being made (cant be reversed).

Calcium Oxide and Water.

charleebaker2029 — 2025-03-03 03:05:36 UTC

This reaction is an exothermic reaction meaning it gives off energy (hot). This is when these two substances get mixed together and the temperature goes from lower to higher.

Chemical Reaction: cao+H2o ->ca(oH)

Burning a candle

charleebaker2029 — 2025-03-03 03:26:36 UTC

When you burn a candle, first off there is no way of reversing it meaning making it normal again but also, there is a change in temperature. These are both good indicators of a chemical reaction. It is an exothermic reaction (hot).

Chemical Equation: C25H52 + 38O2 → 25CO2 + 26H2O

Reactants and Products:
