The mass of the product in a chemical reaction must be equal the mass of the reactants.
The correct answer is polymerization. The synthesis of giant molecules from components of repeating units is polymerization. Polymerization is the process of reaction of molecules together in a chemical reaction that results into a polymer chain.
Answer:
D. The particles move up and down without changing their position
Explanation:
These are gases. They are typically known for their randomness and no fixed arrangement of their atoms.
Gases generally assume the volumes of the containers they fill. They spread easily and readily to fill the volume where they occupy. Also, gases are readily compressible as they lack intermolecular attraction between their molecules.
I'm confused... is there more info?
