HNO3+H2SO4H2O+NO+2+HSO4

Explanation:

This is an acid-base reaction, with sulfuric acid (H2SO4) acting as an acid and nitric acid (HNO3) acting as a base. After the nitric acid gets protonated, it decomposes to form a water molecule (H2O) and a nitronium ion (NO+2). The equilibrium lies very much to the left.

This reaction is commonly a precursor to aromatic nitration.
