If countries are on plate boundaries, such as Japan, they are more prone to earthquakes. If countries are above hot spots, such as Hawaii, they are more prone to volcanoes.
Answer:
O the molecular formula
Explanation:
The true ratio of atoms in a molecule or formula unit is called the molecular formula.
The molecular formula of a compound shows the true number of atoms that are combining to form a compound.
For example, the molecular formula of water is H₂O.
- Empirical formula of a compound is its simplest ratio.
- When the number of atoms are divided by the smallest possible factor, it yields the empirical formula.
C₅H₁₂ + 8O₂ = 5CO₂ + 6H₂O
5CO₂ - 10O
6H₂O - 6O
16O - 8O₂
8 moles of molecular oxygen are consumed
It doesn't exactly mean anything, but it does describe the second group of elements, the Alkali Earth Metals.
