In this video, the calcium chloride and water create an exothermic chemical reaction. When the water was added to the calcium chloride, the temperature began to increase dramatically. This indicates it's an exothermic chemical reaction because heat is being released

# data[].attributes.body
Substances used:
Calcium Chloride, CaCl2
Watere, H₂O

In this video, the sodium hydroxide and phenolphthalein create a chemical reaction. The two clear liquids create this pink color shown above which indicates it's a chemical reaction because of the color change.

# data[].attributes.body
Substances used:
Sodium Hydroxide, NaOH
Phenolphthalein, C₂₀H₁₄O₄

In this video, barium hydroxide and ammonium chloride create a chemical reaction. When the two are put together, it makes the temperature go down which indicates it's an endothermic chemical reaction.

# data[].attributes.body
Substances used:
Magnesium Chloride, MgCl₂
Silver Nitrate, AgNO₃

endothermic dissolution of ammonium nitrate

# data[].attributes.body
Substances used:
Barium Hydroxide, Ba(OH)₂
Ammonium Chloride, NH₄OH

# data[].attributes.body
In this video, sodium carbonate and hydrochloric acid created a chemical reaction. The effervescence created from the reaction between the two substances indicate it's a chemcial reaction.

In this video, sodium iodide and lead nitrate create a chemical reaction. When the two substances come in contact, they create a yellow solid which indicates it's a chemical reaction.

# data[].attributes.body
In this video, ammonia and copper sulfate create a chemical reaction. When the ammonia is added to the copper sulfate, it changes the clear liquid to a blue color which indicates it's a chemical reaction.
