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 2KBr → 2K + Br2 is endothermic because heat must be supplied to break the bonds in potassium bromide (KBr) in order to form potassium (K) and bromine gas (Br2).
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.
The ion MnO4 is reduced toMnO2 and sulfur is oxidized to ion sulfate. Sulfite is the reducing agent.
2K+ + 4H+ + 2O2- = 2K++ 2OH- + H2 Sodium is a reducing metal.
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.
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.
The equation 2K + Br2 -> 2KBr is balanced as there are equal numbers of atoms of each element on both sides of the reaction.
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.
2k + 2h2o --> 2 koh + h2 (Actual chemical symbols are in capital letters, we are having a technical problem.)
The reaction between potassium and fluorine results in the formation of potassium fluoride (KF), a white crystalline salt. The chemical equation for this reaction is: 2K + F2 → 2KF. This is a highly exothermic reaction due to the high reactivity of both elements.
(2k + 3) (2k + 3)
The reaction 2KBr → 2K + Br2 is endothermic because heat must be supplied to break the bonds in potassium bromide (KBr) in order to form potassium (K) and bromine gas (Br2).
8k +2k + 7 = 10k + 7
The complete ionic equation for the reaction is: Ca^2+(aq) + 2NO3^-(aq) + 2K+(aq) + CO3^2-(aq) --> CaCO3(s) + 2K+(aq) + 2NO3^-(aq)
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and potassium (K) is: 2HCl + 2K -> 2KCl + H2.
