Sodium hydrogen carbonate decomposes above 110°c to form sodium carbonate, water, and carbon dioxide. 2nahco3(s) na2co3(s) + h2o

(g) + co2(g) one thousand grams of sodium hydrogen carbonate are added to a reaction vessel, the temperature is increased to 200°c, and the system comes to equilibrium. what happens in this system if another 50 g of sodium carbonate are now added?

The given chemical equation is,

2NaHCO_{3}(aq)  Na_{2}CO_{3}(aq)+CO_{2}(g) + H_{2}O(g)

When sodium carbonate is added the system tries to minimize the effect of the additional product added, by shifting the equilibrium such that the extra product is converted back to the reactants. This takes place until the equilibrium is re-established. Therefore, the equilibrium shifts towards the reactants side. The concentrations of sodium carbonate, carbon dioxide and water vapor decrease while the concentration of sodium hydrogen carbonate increases.

What is the balanced, net ionic equation
Effectus [21]

A net ionic equation which tends to show the ions that underwent a change in the reaction

<h3>What is a reaction equation?</h3>

The term reaction equation is the term that can be used to describe the instance where reactants combine together. If this occurs in solution we can say that the reaction is an aqueous phase reaction because the reactants wee all dissolved in solution.

It is possible for ionic substances in solution to react. When this occurs, it is possible for us to put down a net ionic equation which tends to show the ions that underwent a change in the reaction and the product of this reaction may be a liquid, a gas or a solid.

In this case, the complete molecular equation can be written as;

Ba(NO3)2(aq) + Na2SO4(aq) -----> BaSO4(s) + 2NaNO3(aq)

The complete ionic equation can be written as;

Ba^2+(aq) + 2NO3^-(aq) + 2Na^+(aq) + SO4^2-aq)  -----> BaSO4(s) +  2NO3^-(aq) + 2Na^+(aq)

Net ionic equation is;

Ba^2+(aq) + + SO4^2-aq)  -----> BaSO4(s)
