Molecule
Explanation:
The molecular formula HOH is an example of a molecule.
A molecule is the smallest particle of a substance (element or compound) capable of independent existence.
Molecules can be:
- Monoatomic with one atom e.g Neon, Argon
- Diatomic with two atoms e.g Nitrogen gas N₂
- Polyatomic e.g ozone O₃
The word molecule can also be used to refer to a covalent compound that has discrete or separate units.
The formula HOH or H₂O is a separate covalent that has an independent existence.

Answer:
Finches after drought had stronger and larger beaks to demolish the harder and larger seeds that the drought brought, a difference from those that lived in wet times that had smaller, pointy beaks to eat smaller seeds.
Explanation:
This is called the theory of animal evolution, where animals adapt according to the environment, this theory was just analyzed by this species of animals and many more on the island of Galapagos by Darwin.
What I also approve of as that animal that survives a certain environment is the one that is considered most suitable to live in that place.
Density of an object is computed by dividing its mass by its volume. D = M / V
Solution:
D = 500 g / 2.75 cm3
D = 181.82 g/cm3
Further, density of an object is computed by dividing its mass by its volume. D = M / V
However, since Volume is the missing component in the equation. Mass of an object is divided by its density to get its volume. V = M / D

<span>Volume of Iron Pyrite nugget = 50 g </span>/ <span>5.0g/cm3 = </span>10cm3
