How many carbon atoms are in each compound?
2 answers:
Answer:
Methane: 1
Ethane: 2
Ethene: 2
Pentane: 5
Propene: 3
Hexane: 6
Ethyne: 2
Propane: 3
Hexane: 7
Octane: 8
Decane: 10
Butyne: 4
Butane: 4
Propyne: 3
Butene: 4
Explanation:
Use the chemical formula of the compounds:
Methane ⇒ Hexane ⇒
Decane ⇒
Ethane ⇒ Ethyne ⇒
Butyne ⇒
Ethene ⇒ Propane ⇒
Butane ⇒
Pentane ⇒ Hexane ⇒
Propyne ⇒
Propene ⇒ Octane ⇒
Butene ⇒
In the chemical formulas above, each formula has things known as coefficients (elements) and subscripts (atoms).
So to further explain, take methane as an example, there is a "C" at the beginning. C is capital as it is a pure substance and is a element. This also means there is 1 carbon atom in methane while there is 4 oxygen atoms. But to explain further, let's review definitions:
<h3>What is a compound in chemistry</h3>A pure substance composed of two or more elements composed of two or more elements.
<h3>What is a pure substance in chemistry</h3>A pure substance is a single element or compound, not mixed with any other substance
<h3>What is a element in chemistry</h3>One of a class of substances that cannot be separated into simpler substances by chemical means.
<h3>What is a chemical formula (Alternative name for molecular formula)</h3>A chemical formula that indicates the kinds of atoms and the number of each kind in a molecule of a compound.
So after reviewing let's find the carbon atoms.
The subscripts in each chemical formula that are to the right to the "C" are the amount of carbon atoms. If a capital letter does not have a subscript, it is assumed to have 1 atom only.

This is an incomplete question, here is a complete question.
The given molecule is, and structure is shown below.
Determine the number of shared and unshared electrons in the structure.
Shared (bonding) electrons :
Unshared (lone, non-bonding) electrons :
Answer :
Shared (bonding) electrons : 8
Unshared (lone, non-bonding) electrons : 16
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that sulfur and oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in = 6 + 3(6) = 24
Bonding electrons : These are those electrons that are shared between the atoms resulting in the formation of bond.
Non-bonding electrons : They are the valence electrons of the atom which are not shared with another atom.
According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
