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 for germanium plus sulfur is Ge + S -> GeS.
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.
This is not a chemical formula or equation.
Chemicals equations use chemical formulas and other symbols instead of words to summarize a reaction.
The chemical equation for this photosynthesis reaction is: 6CO2 + 6H2O → C6H12O6 + 6O2.
The chemical equation for Na2S (sodium sulfide) reacting with H2O (water) is: Na2S + H2O → 2NaOH + H2S
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.
The chemical equation for magnesium reacting with iodine is: Mg + I2 -> MgI2
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
The balanced chemical equation is: C2H6S + 5O2 -> 2CO2 + 3H2O + 2SO2. This equation is balanced as it has the same number of each type of atom on both sides of the reaction arrow.
