Answer:
The different elements are represented by their symbols one line shows a single bond and two lines show a double bond. This written representation is called a structural diagram
8 carbons is "oct" prefix (like polygons)
No pi bonds is "ane" suffix.
put it together to get.... Octane
Answer:
I do not know the Answer I'm just trying to get my point
Explanation:
Thank you
<span>Carbon can also bond with other
four atoms because of its outer shell (valence shell) that has four electrons.
This is the reason why organic molecules can be so large because of this
bonding. Suppose you have a compound of CCl4. You know that chlorine can only
share 1 electron because 7 of its electrons are filled. Also, in carbon, it can
only share 4 electrons because 4 of it are already filled. That is why carbon
needs four chlorine to form CCl4. The answer is letter <u>B.</u></span>
The volume of O₂ : 21 L
<h3>Further explanation</h3>
Given
8.7 grams of C₂H₄
Required
Volume O₂
Solution
Reaction
C₂H₄ + 3 O₂ ⇒ 2 CO₂ + 2 H₂O
mol C₂H₄(MW= 28 g/mol) :
= mass : MW
= 8.7 g : 28 g/mol
= 0.311
From the equation, mol O₂ :
= 3/1 x mol C₂H₄
= 3/1 x 0.311
= 0.933
At STP, 1 mol gas=22.4 L, so for 0.933 mol :
= 0.933 x 22.4 L
= 20.899 L ≈ 21 L
