The given reaction is an example of "synthesis" reaction, in particular one in which two elements react to form a chemical compound.
The reaction between 2 moles of potassium (K) and 1 mole of iodine (I2) to form 2 moles of potassium iodide (KI) is a combination or synthesis reaction. In this reaction, two elements are reacting to form a single compound.
synthesis reaction
The given reaction represents a double displacement reaction also known as a metathesis reaction. In this type of reaction, the cations and anions of two different compounds switch places to form two new compounds.
This is a double replacement reaction which forms barium sulfate and salt (NaCl) when the sodium ions in sodium sulfate (mirabilite) remove chlorine from barium chloride.
The formations of these compounds from elements are as follows. 2 Na + S --> Na2S 2K + I2 --> 2KI These two reagents do not react with each other.
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 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 between 2 moles of potassium (K) and 1 mole of iodine (I2) to form 2 moles of potassium iodide (KI) is a combination or synthesis reaction. In this reaction, two elements are reacting to form a single compound.

When iron reacts with potassium iodide, it forms potassium iodide. The reaction can be written as 2Fe + 2KI → 2K + 2FeI. Potassium iodide is a salt and is commonly used as a nutritional supplement.
One atom of potassium will react with one atom of iodine according to the balanced chemical equation for the reaction between potassium and iodine: 2K + I2 → 2KI.
2k + 2h2o --> 2 koh + h2 (Actual chemical symbols are in capital letters, we are having a technical problem.)
14KMnO4 + 4C3H5(OH)3 --> 7K2CO3 + 7Mn2O3 + 5CO2 + 16H2O
No, the reaction 2K + Br2 is not balanced. To balance it, you would need to change the coefficients of the reactants and products so that the same number of each type of atom is present on both sides of the reaction arrow.
