Answer:
Subatomic particles making up an atom
Explanation:
Atom is the smallest unit of any matter
An atom consists of three subatomic particles - Protons, Neutrons, Electrons. Major atomic mass is in the nucleus ie a tiny deep area at the centre. Nucleus consists nucleons, which includes protons (positively charge) & neurons (neutrally charged). Negatively charged electrons are outside the central nucleus.
Answer:
No
Explanation:
It is not correct to say that an object with the largest volume has the largest mass.
Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.
Mass is the amount of matter in a substance. Volume is the space a body occupies.
- A balloon and a stone for example is a typical one.
- A balloon has more volume but far lesser mass compared to a stone.
- A stone, gravel sized has low volume but more massive than a balloon.
Therefore, it is wrong to say a balloon has more mass because it has more volume.
The answer is B hope this helped
Ideal Gas Law
Given: P1= 1.25 atm P2= 95 atm
V1= 2.50 L
Unknown: V2=?
Formula: V=nRT/P; n = RT / PV
Solution: n = (0.0821 L x atm / K x mol) (285K) / (1.25 atm) ( 2.50L)
= 23.40 / 3.125
Answer: n = 7.49 moles of gas the balloon holds
