The reactants are the pure aluminum and ion oxide with the aluminum powder. The product is Iron and aluminum oxide.

# data[].attributes.body
Aluminum Poder: 2Al(s)  +
pure aluminum and ion oxide: Fe₂O₃(s) = 2Fe(s) + Al₂O₃ (s)

# data[].attributes.body
This reaction is extremely exothermic. The pure aluminum and ion oxide combined with aluminum powder together when activated produce iron and aluminum oxide. A temperature change and new substance is created.

# data[].attributes.body
In this video we see aluminum powder, combined with pure aluminum and ion oxide (rust). The solid is in a cup along with a sparkler. The sparkler gives the solid the activation it needs to react. The reaction produces iron and aluminum oxide.

The reactants are Lead Nitrate and Sodium Iodide. The product is Lead Iodide.

# data[].attributes.body
Lead Nitrate: Pb(NO3)2  +
Sodium Iodide: NaI  =

Lead Iodide: PbI2

# data[].attributes.body
There are 3 indicators a chemical reaction took place. The two clear liquids produced a yellow solid. A color change and and a change in matter. When the Lead Nitrate's and Sodium Iodide's atoms combined, it formed a new substance; Lead Iodide. Lead Iodide is a yellow solid.

# data[].attributes.body
In this video we see Lead Nitrate and Sodium Iodide dissolved in water. When the two substances are mixed together, we see a reaction occur. The two liquids produce a solid and change color.

# data[].attributes.attachment_link.description
Lead Nitrate and Sodium Iodide are each dissolved in water. The two dissolved substances are then added together and a reaction occurs: Sodium Nitrate is formed and remains dissolved in the water. Lead Iodide is also formed. However Lead Iodide is a solid and a brilliant yellow!

Chemical Equation for a turquoise firework 

# data[].attributes.body
copper compounds + chlorine producer
copper acetoarsenite (Green), Cu₃As₂O₃Cu(C₂H₃O₂)₂ = blue
copper (I) chloride, CuCl = turquoise blue

# data[].attributes.body
The electrons from the CuCl₂ start to heat up and gain temperature. The firework explodes because its fuel, oxidant, and element are all heated up. The elements electrons are becoming 'excited' from the heat. The element used gives the firework its color. For example, copper would produce a green firework. The color the element gives off is caused by the difference in energy levels of the electrons.

# data[].attributes.body
In this video we can see beautiful fireworks exploding. We can take the green firework as an example here. The green firework is made from CuCl₂, fuel, and the proper oxidant. The firework is heated and shot into the sky, and proceeds to explode.

The reactants are the caustic soda and water solution and the potassium permanganate. The product is manganese(IV) oxide.

# data[].attributes.body
caustic soda (NaOH) and water (H2O)  +  potassium permanganate (KMnO4)  =  manganese(IV) oxide (MnO2)

# data[].attributes.body
The Potassium Permanganate  reacts with the sugar from the caustic soda and water solution. This forms potassium manganate, which is green. This reaction keeps occurring, until finally the color stops at a brownish-orange. This final solution is manganese (IV) oxide.

# data[].attributes.body
In this chemical reaction, we have a solution of caustic soda and water. Potassium Permanganate- a purple substance is added into the solution. The solution is spun by a magnetic stirrer and changes colors several times.

The reactants are the thiols. The produce the stinky skunk spray- the product.

# data[].attributes.body
2-butene-1-thiol:   C ₄ H ₈ S
3-methyl-1-butanethiol:    (CH ₃)₂ CHCH ₂ CH ₂ SH
Added together equal skunk spray!

# data[].attributes.body
Skunk spray consists of a mixture of chemicals containing sulfur. It is composed of 7 components that are extremely volatile. These 7 components can be divided into thiols and acetate derivatives of the thiols. 2-butene-1-thiol and 3-methyl-1-butanethiol are responsible for the stink the spray causes.

In the picture above we can see a chemical reaction occur. The skunk is spray a disgusting odor out of it's rear end.

The reactants are baking soda and vinegar. The product they produced is Carbon Dioxide.

# data[].attributes.body
NaHCO3  +  CH₃COOH  =  CO₂

# data[].attributes.body
When the vinegar dissolves the baking soda, it creates CO₂. We can see that a chemical reaction takes place because of two indicators. When the baking soda hits the vinegar, it fizzes up which is one indicator. The second indicator is a new substance forming- CO₂.

# data[].attributes.body
In  this video we see a reaction occur between vinegar and baking soda. When the vinegar is mixed with the baking soda, it starts to fizz up, releasing CO₂. The carbon dioxide extinguishes the candle because the flame doesn't have access to oxygen.
