The acid dissociation constant ka equals 1.26 × 10–2 for hso4– and is 5.6 × 10–10 for nh4. which statement about the following equilibrium is correct? hso4–(aq) + nh3(aq) so42–(aq) + nh4+(aq)

From the reaction, we can conclude the following about equilibrium;

The reaction will favour the reactants because ammonia is a stronger base compare to the sulphate ion.

petroleum? coal maybe?

gravity causes stares to cluster i think so
