Yes there elements can have various numbers of neutrons
Acids and bases are fairly important for the fact that they are very essential to the human body. As well as they balance the Ph levels in our body. You can use acids and bases to nurtralize eachother aswell
Answer:
The NH⁺₄ and SO₄²⁻ are spectator ions.
Explanation:
Chemical equation:
NH₄OH(aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq) + H₂O(l)
Balanced Chemical equation:
2NH₄OH(aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq) + 2H₂O(l)
Ionic equation:
2NH⁺₄(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2NH⁺₄ (aq) + SO₄²⁻(aq) + 2H₂O(l)
Net ionic equation:
2OH⁻(aq) + 2H⁺(aq) → 2H₂O(l)
The NH⁺₄ and SO₄²⁻ are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
