✔ 最佳答案
HCl(g)Because H2SO4(l) is non-volatile and HCl is gaseous state in room temperature and pressure.
H2SO4(l)+2NaCl(aq)---->Na2SO4(aq)+2HCl(g)

No gas occured.
Although conc. sulphuric acid is a very weak oxidizing agent
Na+ is stronger than conc. sulphuric acid, so no reaction occured.

The equation should be as follows:
H2SO4 + NaCl -----> NaHSO4 + HCl
Gas released is HCl.
H2SO4 + NaCl -----> NaHSO4 + HCl
Gas released is HCl.
