2SO2 (g) + O2 (g)→2SO3 (g), ΔH = −198 kJ
What is the missing ΔH?
−594 kJ
−198 kJ
+198 kJ
+792 kJ

Does the number of ions in solution increase, decrease, or remain constant? it continuously decreases. it continuously increases. it decreases at first, then increases. it increases at first, then decreases.
