Question

Write the formula of the following compounds: 1. Hydrochloric acid 2. Iron sulphide 3. Blue vitriol 4. Silver nitrate 5. Steam 6. Sulphuric dioxide 7. Methane 8. Sulphuric acid 9. Zinc oxide 10. Copper oxide ​

Answer 1

Answer:

1. HCl
2. FeS
3. CuSo4
4. AgNO3
5. Steam is essentially water in gas-like state so it's formula will be H2O.
6. Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO2, SO3, S7O2, S6O2, S2O2, etc. I think there'll be Sulphuric Dioxide, so it's formula is SO2.
7. CH4
8. H2SO4
9. ZnO
10. CuO
