Answer:
Net ionic equation:
Ca⁺²(aq) + CO²⁻₃(aq) → CaCO₃(s)
Explanation:
Chemical equation:
K₂CO₃ + CaCl₂ → KCl + CaCO₃
Balance chemical equation:
K₂CO₃(aq) + CaCl₂(aq) → 2KCl(aq) + CaCO₃(s)
Ionic equation:
2K⁺(aq) + CO²⁻₃(aq) + Ca⁺²(aq) + 2Cl⁻(aq) → 2K⁺(aq) + 2Cl⁻(aq) + CaCO₃(s)
Net ionic equation:
CO²⁻₃(aq) + Ca⁺²(aq) → CaCO₃(s)
The K⁺(aq) and Cl⁻ (aq) are spectator ions that's why these are not written in net ionic equation. The CaCO₃ 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.
The net ionic equation for the reaction between K2CO3 and CaCl2 is Ca2+(aq) + CO3^2-(aq) --> CaCO3(s). This is obtained after removing the spectator ions (K+ and Cl-) from the full ionic equation.
The subject of discussion is the net ionic equation for the given chemical reaction between K2CO3(aq) and CaCl2(aq). An ionic equation represents the ions that are present in a chemical reaction, and a net ionic equation only shows the ions that actually participate in the reaction.
To form the net ionic equation, we first write the complete ionic equation. In this case, K2CO3(aq) breaks down into 2 K+(aq) + CO3^2-(aq), and CaCl2(aq) breaks down into Ca2+(aq) + 2 Cl-(aq). The products would be 2 K+(aq) + 2 Cl-(aq) + CaCO3(s).
The net ionic equation is then formed by canceling out the spectator ions (ions that do not participate in the reaction). Here, the spectator ions are K+ and Cl-. So, the net ionic equation is: Ca2+(aq) + CO3^2-(aq) --> CaCO3(s)

The tail of a comet always points away from the Sun.
The tail of a comet always points away from the Sun. This is due to the interaction between the Sun's radiation and the comet's gas and dust particles. As the comet gets closer to the Sun, the solar radiation causes the ice within the comet to vaporize and release gas and dust particles, forming a glowing tail that always faces away from the Sun.

Answer:
A. Le Chatelier's principle
Answer and Explanation:
It is worthy to be mentioned that the equilibrium in this reaction is dynamic equilibrium.
Answer:
In a chemical reaction equilibrium is in the state which reacts with both products and reactants. Both reverse and forward are happening and both reaction rates forward and reverse are equal.
