it is a chemical change because there is two new solutions created and they cannot be transformed back, making it a chemical change.
When sodium hydroxide (NaOH) is reacted with iron (II) sulfate (FeSO4), it forms iron (II) hydroxide (Fe(OH)2) and sodium sulfate (Na2SO4). The balanced chemical equation for the reaction is: 2NaOH + FeSO4 -> Fe(OH)2 + Na2SO4
No. It is a physical process, so it technically isn't a reaction.
When adding NaOH to HCl, a chemical change occurs because the two substances react to form a new compound, NaCl (table salt), and water. This is evidenced by the formation of a new substance with different properties than the original reactants.
The balanced molecular equation for the reaction between ferrous sulfate (FeSO4) and sodium hydroxide (NaOH) is: FeSO4 + 2NaOH -> Fe(OH)2 + Na2SO4.

It is a chemical reaction for not only has the state changed of NaOH, but the identity of the substances have also changed.NaOH + H2O --> Na+ + OH-The "H2O" is not a reactant. It's actually supposed to go over the arrow. Sorry.Nonetheless, the dissolution of NaOH will increase the Hydroxide concentration, thus making it more basic. It will not change the identity of H2O.
The balanced molecular equation for the reaction between ferrous sulfate (FeSO4) and sodium hydroxide (NaOH) is: FeSO4 + 2NaOH -> Fe(OH)2 + Na2SO4.

NaOH.
The chemical formula for sodium hydroxide, commonly known as NaOH, is NaOH.
The chemical formula for sodium hydroxide is NaOH, while the chemical formula for hydrochloric acid is HCl.
The chemical equation for the reaction of TiOCl with NaOH is: TiOCl2 + 2 NaOH → Ti(OH)2 + 2 NaCl
Because the molecule of NaOH can be recovered unchanged from the solution.
unnecessary will change physically depending on what type of reaction, sometime chemically change . For example physically change are ice to water (solid to liquid) Chemically change are HCl + NaOH = NaCl + H2O ( the content changed )
