I think the correct answer would be the third option. The correct name for the hydrocarbon described above would be 2-heptyne. It has a chemical formula written as CH3 - CH2 - CH2 - CH2 - C ≡ C - CH3. Counting the number of carbons, we have 7 carbon atoms so we use the prefix hepta-. Since it has a triple bond then it is an alkyne. So, it would be named as heptyne. The triple bond is located on the second carbon atom so we write 2 before the name to indicate the location of the triple bond. The name of the compound would be 2-heptyne.
Answer:
I think C. Hope this Helps!
Explanation:
Answer:
fluoride ion with a charge of -1
Explanation:
If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
There are 3 ions in one formula unit of (NH4)2CO3.
Ions present in Ammonium carbonate.(NH4)2CO3
(NH4)2CO3 is called Ammonium carbonate. The formula indicates that in one mole of ammonium carbonate, There are
- Two moles of ammonium ions,NH₄⁺ with valency of +1.
- 1 mole of Carbonate ions CO₃²⁻ with valency of -2.
When 1 mole of ammonium carbonate is dissolved in water it gives
(NH₄)₂CO₃ ₊ H₂O---->2NH₄⁺ ₊ CO₃²⁻
Ions present are 2NH₄⁺ and CO₃²⁻
