Answer:
CO₃²⁻(aq) + 2H⁺(aq) → CO₂ (g) + H₂O (l)
Explanation:
The balanced reaction between Na2CO3 and HCl is given as;
Na₂CO₃ (aq) + 2 HCl (aq) → 2 NaCl (aq) + CO₂ (g) + H₂O (l)
The next step is o express the species as ions.
The complete ionic equation for the above reaction would be;
2Na⁺(aq) + CO₃²⁻(aq) + 2H⁺(aq) + 2Cl⁻(aq) → Na⁺(aq) + Cl⁻(aq) + CO₂ (g) + H₂O (l)
The next step is to cancel out the spectator ion ions; that is the ions that appear in both the reactant and product side unchanged.
The spectator ions are; Na⁺ and Cl⁻
The net ionic equation is given as;
CO₃²⁻(aq) + 2H⁺(aq) → CO₂ (g) + H₂O (l)
I suppose it could be <span>Xenon, but I'm not pretty sure about this.</span>
Answer:

Explanation:
Reactions:
With: ![K_1=\frac{[NO][O]}{[NO_2]}=6.8*10^{-49}](https://tex.z-dn.net/?f=K_1%3D%5Cfrac%7B%5BNO%5D%5BO%5D%7D%7B%5BNO_2%5D%7D%3D6.8%2A10%5E%7B-49%7D)

With: ![K_2=\frac{[NO_2}{[O_3][NO]}=5.8*10^{-34}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BNO_2%7D%7B%5BO_3%5D%5BNO%5D%7D%3D5.8%2A10%5E%7B-34%7D)
To achive the reaction we combine those two reactions:
The equilibrium constant:
