Ice cubes are made of water which has undergone freezing, which made it into ice. Both ice cubes and water have the same properties. But in this case, when ice and water are mixed, it is considered a heterogeneous mixture and not homogeneous. Why? Going back to the definition of what a heterogeneous mixture is, this mixture shows a visible difference of difference phases or substances. In the ice and water mixture, it is obviously seen that ice is solid, and water is liquid.
What? Why does it have a question mark it makes no sense because there isn’t any options and you didn’t explain what the question is about.
It is transferred onto the next animal. Think of it as the trophic level system: since the animal is being used for food, its energy is being used by the next animal.
Answer:
Explanation:
Chemical equation:
HCl + Fe₂O₃ → FeCl₃ + H₂O
Balanced Chemical equation:
6HCl (aq)+ Fe₂O₃(s) → 2FeCl₃(aq) + 3H₂O(l)
Ionic equation:
6H⁺(aq) + 6Cl⁻(aq) + 2Fe⁺³(aq) + 3O²⁻(aq) → 2Fe⁺³(aq) + 6Cl⁻(aq) + 3H₂O(l)
Net ionic equation:
6H⁺(aq) + 3O²⁻(aq) → 3H₂O(l)
The Cl⁻(aq) and Fe⁺³(aq) 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.
