If calcium carbonate decomposes, the product of the reaction would be calcium oxide and carbon dioxide.
Balanced chemical reaction: CaCO₃(s) → CaO(s) + CO₂(g).
CaCO₃ is calcium carbonate.
CaO is calcium oxide
CO₂ is carbon dioxide or carbon(IV) oxide
Chemical decomposition is the separation of a single chemical compound (in this example calcium carbonate) into its two or more simpler compounds (in this example calcium oxide and carbon dioxide).
Decomposition is reaction where one substance is broken down into two or more simpler substances. Heat is usually necessary to this type of reaction.

Answer:
Light demonstrates wave-like and particle-like characteristics
Explanation:
Light itself is a wave but under circumstance it will present particle-like charcteristics. This is called wave-particle duality :)
Answer:
Mixing colored lights & mixing colored paints. The primary colors of light are also known as the additive colors, because, when you add these three colors of light (red, green and blue) your brain perceives white light. The primary colors of paints, however, are known as subtractive colors.

Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.
<h3>What is a separation technique?</h3>
A separation technique can be defined as a technique that is used to separate (convert) two or more mixture and solution of chemical substances into distinct products such as solutes, chemical compounds or elements.
<h3>What is a chemical element?</h3>
A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.
Generally, some examples of a chemical element include the following:
In Chemistry, sodium hydroxide, caustic soda, or lye all refer to the same chemical compound which is represented by this chemical symbol, NaOH.
According to the narration, Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.

79,200 feet.
Just multiply the total miles times the amount of feet in a single mile.
15 X 5280 ft= 79,200 feet
