Which of the following substances react with sulfuric acid: BaO, SO2, AI (OH) 3, ZN, HNO3, Cu

Sulfuric acid reacts with metals standing in a series of voltages to the left of hydrogen, metal oxides, bases and salts:
H2SO4 (expanded) + Zn = Zn SO4 + H2 ↑
BaO + H2SO4 (dil.) → BaSO4 + H2O
Al (OH) 3 + 3H2SO4 → Al (SO4) 3 + 3H2O
Copper is among the stresses after hydrogen – therefore, dilute sulfuric acid does not act on copper.
Diluted and concentrated sulfuric acid behave differently. Zinc, as an active metal, can form sulfur dioxide, elemental sulfur, and even hydrogen sulfide with concentrated sulfuric acid.
2H2SO4 (conc.) + Zn = SO2 ↑ + ZnSO4 + 2H2O
Copper is a less reactive metal. When interacting with concentrated sulfuric acid, it reduces it to sulfur dioxide.
2H2SO4 (conc.) + Cu = SO2 ↑ + CuSO4 + 2H2O
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
