Write the formula of each of the following
1. Ferrous sulfide
2. Sodium sulphite
3. Magnesium carbonate
4. Hydro sulfuric acid
1. FeS
2. Na2SO3
3. MgCO3
4. H2S
1. The formula for Ferrous sulfide is FeS.
2. The formula for Sodium sulphite is Na2SO3.
3. The formula for Magnesium carbonate is MgCO3.
4. Hydro sulfuric acid is a compound that does not exist. However, if you meant Hydrogen sulfide (H2S) instead, then the formula would be H2S.
