Answer:
what is this question in the physics
Answer:
a. Decomposition.
Explanation:
A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y ⇒ XY.
- Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements.
- A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces other element in a compound.
- A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (action) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Hence, the answer is a decomposition reaction.

Explanation:
Hello!
In this case, since Helium is undergoing a volume-pressure change, according the Boyle's law, we infer the following equation is used:
Thus, since we are not given the volume at 0.25 atm, we can solve for V2 to do so:
Thus, we plug in to obtain:
Best regards!
Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.
