What is the net ionic equation for the reaction if any that occurs when aqueous solutions of Na2CO3 and HCL are mixed?
strojnjashka [21]

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)

HELP! I NEED THIS ANSWERED ASAP!!!
stealth61 [152]

Answer:

The rate of reaction will maintain constant

Explanation:

Rate of reaction is proportionate to rate constant x [A] ^2 x [B]. This means that the order of reaction with respect to C is 0 as it does not affect the rate of reaction as seen in the rate equation.

Essentially, order of reaction with respect to C is [C] ^0

Hence if [C] triples and becomes [3C]^0, the result will still be 1 as anything to the power of 0 is 1.

Therefore, the answer is that the rate of reaction will remain constant.
