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,

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.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
