Question

(NaNO_3 (s) + H_2SO_4 (l) → NaHSO_4 (s) + HNO_3 (g)) (Δ H = 21.2 , {kJ}) How much heat must be absorbed by the reaction system to convert 100g of (NaSO_3) into (NaHSO_4 (s))?

Answer 1

To calculate the amount of heat absorbed by the reaction system, additional information such as molar masses and the balanced chemical equation is needed. However, there is likely a typo in the provided chemical equation involving NaNO3 and Na2SO3.

Step-by-step explanation:

The question you've provided involves the calculation of heat change during a chemical reaction, which is a concept within the field of thermochemistry. Specifically, the reaction of sodium nitrate (NaNO3) with sulfuric acid (H2SO4) to produce sodium hydrogen sulfate (NaHSO4) and nitric acid gas (HNO3 (g)) is described.

The reaction is endothermic, with a heat change (ΔH) of 21.2 kJ. To calculate the amount of heat absorbed when converting 100g of sodium sulfite (Na2SO3) into sodium hydrogen sulfate, more information is needed, such as the balanced chemical equation and molar masses.

However, from the context, it seems there was a typo, and the correct reactant is likely sodium nitrate, NaNO3.
