They’re put in groups that have similar properties to them. but the periodic table is organized by atomic numbers.
It is true and the person above me is also right
The molar heat of vaporization of substance Z is 3.375 kJ/mol.
<h3>
Molar heat of vaporization of substance Z</h3>
The molar heat of vaporization of substance Z is calculated as follows;
ΔH(vap) = E/n
where;
- E is the energy required
- n is number of moles
ΔH(vap) = 5.4 kJ/1.6
ΔH(vap) = 3.375 kJ/mol
Thus, the molar heat of vaporization of substance Z is 3.375 kJ/mol.

Answer:
When two negatively charged particles interact with one another, the particles repel with each other. Opposite charges attract while like charges repel. A negatively charged object will exert a repulsive force upon a second negatively charged object.
Explanation:
There are certain rules to follow when naming covalent compounds. But first, let us look at the definition of Covalent Compounds.
<h3>
What are Covalent Compounds?</h3>
When covalent bonds aid the creation of a molecule, in which the atoms have at least one similar pair of valence electrons, a covalent compound is said to have been formed.
A very common example is water (H₂O)
<h3>
How are Covalent Compounds named?</h3>
To name a covalent compound, simply list the first element in the formula using the name of the element, then name the second element by adding the suffix "ide" to the stem of the second element's name.
If there is only one atom in the molecule of the first element, then no prefix should be added.
It is to be noted that if the second element in the compound is oxygen, then we should say:
- monox<em>ide</em> instead of monoox<em>ide</em> and
- triox<em>ide</em> instead of trox<em>ide</em>, all depending on how many atoms that are involved.
See the attached for the prefixes related to the various number of atoms in the compounds.
It is to be noted that the covalent compound to be named here is not stated hence the general answer.
