1.
n = m/2.016 g/mol = V/22.4 l
V = 22.4 l
Hence,
m = 2.016 g ≈ 2.02 g
B.) 2.02 g
2.
Balancing the equation, we get,
Mg + 2HCl → MgCl2 + H2
PV = nRT
V = nRT/P
V = 1.5 mol × 8.314 atm/(mol.K) × 298 K/(0.96 atm)
V = 3871.206
V ≈ 38.2 l
Explanation:
Liquids cannot change volume but gases can because they have a fixed shape like solids.
Liquids have strong intermolecular forces binding their molecules together resulting is fixed ordering.
- Gases are randomized with their molecules haphazardly arranged.
- This allows them to expand spontaneously on their own.
- Molecules of liquids are more tightly packed compared to gases.
- In a liquid, the molecules have a less random pattern of motion and can only slide past one another.
- In a gas, the molecules are in continuous random, straight line motion.

Answer:
I can say that it is not a compound because I got it wrong
Explanation:
Hello! My name is Zalgo and I am here to help you out today. The most common form of matter in the universe would be "Plasma". Plasma is gas that is heated a lot so it turns into high energy (high energy would be said "Plasma").
I hope that this helps! :D

The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.
<h3>What is an atom?</h3>
An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.
The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.
The atomic mass can be given as:
The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:
The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.
