Reactant
This depends on the specific reaction.
Iron (II) sulfate is the correct name for this compound. The Fe ion has a charge of 2 and so does the sulfate ion, so there is no subscript after them.
This depends on the reaction involved.
Since the product, K2SO4 has twice as many potassium atoms as the reactant, KNO3, we may conclude that it takes two moles of reactant to produce one mole of product. The sulfate and nitrate ions will not be the limiting factor.
product
Iron sulfate can be both a reactant and a product in different chemical reactions. When iron reacts with sulfuric acid, iron sulfate is produced as a product. However, when iron sulfate reacts with other chemicals, it can also act as a reactant in the reaction.
Lead sulfate is the product.
It may be either a reactant or a product depending on what the reaction is. If you react elemental zinc with sulfuric acid to form zinc sulfate and hydrogen, then it is a product. If you react aqueous zinc sulfate with sodium hydroxide to form solid zinc hydroxide and sodium sulfate, then it is a reactant.
Iron sulfate, also known as iron(II) sulfate, can be a reactant in chemical reactions. It is commonly used in various industrial processes, such as in the production of iron oxide pigments, treating wastewater, and in the synthesis of other chemical compounds.
Lead sulfate is the product.
It may be either a reactant or a product depending on what the reaction is. If you react elemental zinc with sulfuric acid to form zinc sulfate and hydrogen, then it is a product. If you react aqueous zinc sulfate with sodium hydroxide to form solid zinc hydroxide and sodium sulfate, then it is a reactant.
The product of iron sulfate reacting with calcium carbonate is iron carbonate and calcium sulfate. The iron from the iron sulfate displaces the calcium in the calcium carbonate to form iron carbonate, while the sulfate from the iron sulfate combines with the calcium to form calcium sulfate.
Reactant.
Iron sulphate can be both a reactant and a product, depending on the chemical reaction. It can react to form different compounds or be produced from the reaction of iron and sulphuric acid.
This depends on the specific reaction.
The salt product formed when iron reacts with sulfuric acid is iron sulfate, also known as ferrous sulfate.
There is no elemental iron (Fe) involved in this reaction, neither as reactant (iron sulphide -FeS- plus oxygen are) nor as product (iron oxide (FeO) plus sulphur dioxide are)
