Answer:
The Cl⁻ and K⁺ are spectator ions.
Explanation:
Balanced Chemical equation:
BaCl₂(aq) + K₂CrO₄(aq) → BaCrO₄(s) + 2KCl (aq)
Ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + 2K⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s) + 2k⁺(aq) + 2Cl⁻ (aq)
Net ionic equation:
Ba²⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s)
The Cl⁻ and K⁺ are spectator ions that's why these are not written in net ionic equation. The BaCrO₄ can not be splitted into ions because it is present in solid 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.
Answer:
It has direction and size.
Explanation:
The way I learned it was that vectors have direction and Magnitude. Magnitude is just the length of the vector. So you are right.
En Quimica, una reaccion de deshidratacion es una conversion que implica la perdida de agua de la molecula o ion que reacciona.Las reacciones de deshidratacion son procesos comunes, lo contrario de una reaccion de hidratacion.Los agentes deshidratantes comunes ultilizados en la sintesis organica incluyen acido sulfurico y alumina.
