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.

Answer:
Heat, Q = 262 kJ
Explanation:
Given that,
Mass of a sample, m = 750 g
Initial temperature,
Final temperature,
The specific heat of the sample,
We need to find the amount of heat released. The amount of heat released is given by the formula as follows :
So, 262 kJ of heat is released by the sample.
Answer:
The pH of the solution is 4.69
Explanation:
Given that,
Mass of potassium = 2.643 grams
Weight of water = 50.00 mL
Weight of HCl=100.00 ml
Mole = 0.120 M
We know that,
is a basic salt.
Let's write it as KY.
The acid would become HY.
We need to calculate the moles of KY
Using formula of moles
The reaction is
The number of moles of KY is 20.98 m
initial moles = 20.98
Final moles
We need to calculate the value of pKa(HY)
Using formula for pKa(HY)
We need to calculate the pH of the solution
Using formula of pH
Put the value into the formula
Hence, The pH of the solution is 4.69
1. carbon lies in the 2nd period where silicon in the third period.
2. carbon is a non metal whereas silicon is a metalloid.
3. there are only 3 isotopes of carbon and 23 isotopes of silicon
4. size of silicon atom is larger
5. silicon is heavier than carbon.
7. Neutralisation. Which would (obviously) appear GREEN on the chart.
