The reaction represented is a single displacement reaction, where potassium (K) displaces iodine (I2) from potassium iodide (KI) to form potassium iodide and elemental iodine.
The reaction represented by 2K + I2 is a combination or synthesis reaction, where potassium (K) and iodine (I2) combine to form potassium iodide (KI).
The reaction you've provided is a combustion reaction. In this reaction, methane (CH4) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) as products.
The reaction represents a single replacement reaction where the metal displaces the hydrogen in the acid to form a salt and releases hydrogen gas as a byproduct.
The reaction represented by Fe + CuSO4 → Cu + FeSO4 is a single displacement reaction, also known as a single replacement reaction. In this process, iron (Fe) displaces copper (Cu) from copper(II) sulfate (CuSO4), resulting in the formation of iron(II) sulfate (FeSO4) and elemental copper. This type of reaction typically occurs between a more reactive metal and a compound of a less reactive metal.
It is a hydration reaction.
