Rust
Here :
Fe2O3 + xH2O-> Fe2O3.xH2O(Rust)
FeO + xH2O-> No visible change
x is any number of water molecules.
The chemical equation is:3 NaOH + FeBr3 = 3 NaBr + Fe(OH)3
This is not a chemical formula or equation.
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.
This is the chemical reaction for burning of propane.
The arrow "->" signifies that the reactants in a chemical equation yield the products.
The chemical equation is:3 NaOH + FeBr3 = 3 NaBr + Fe(OH)3
The chemical equation is C7H4O9
The plus sign in a chemical equation indicates the presence of more than one reactant or product. It separates individual chemical species on either side of the equation.
Chemicals equations use chemical formulas and other symbols instead of words to summarize a reaction.
