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.
<span>They have similar or common ancestor. The similarities inherited from the common ancestor as in the case of homologous organs. In evolutionary biology a group of organisms share a common descent if they have a common ancestor. There are many other examples like in the case of hemoglobin to prove the theory of common ancestor</span>
Random errors will shift each measurement from its true value by a random amount and in a random direction. These will affect reliability (since they're random) but may not affect the overall accuracy of a result.
Answer:
A Family Portrait
That element is NOT in the family. When we told you about families, we said that they were groups of elements that react in similar ways. Hydrogen is a very special element of the periodic table and doesn't belong to any family. While hydrogen sits in Group I, it is NOT an alkali metal.
