Expert Answer:
1. concentrated sulphuric acid reacts with solid sodium chloride in the cold to produce hydrogen chloride and sodium hydrogensulphate.
2. calcium fluoride, CaF2 react with concentrated sulfuric acid, H2SO4 to form hydrogen fluoride.
CaF2(s) + H2SO4(l) -> 2HF(g) + CaSO4(s)
3. Copper reacts with sulphuric acid to give copper sulphate, sulphur dioxide and water
4
concentrated sulfuric acid oxidizes carbon
- C + 2 H2SO4 ? CO2 + 2 SO2 + 2 H2O
