The balanced equation is 2K + Br2 → 2KBr. This equation shows that two moles of potassium (2K) react with one mole of bromine (Br2) to produce two moles of potassium bromide (2KBr).
KCl: 2K(s) + Cl2(g) -> 2KCl(s) Br2: Br2(l) -> 2Br(s)
The coefficient for H2O is 1 in the balanced equation: 2K + 2H2O + 2KOH + H2
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and potassium (K) is: 2HCl + 2K -> 2KCl + H2.
The balanced equation is 2K + 2H2O -> 2KOH + H2, balancing the atoms on both sides of the equation.
The balanced equation is 2K + Br2 → 2KBr. This equation shows that two moles of potassium (2K) react with one mole of bromine (Br2) to produce two moles of potassium bromide (2KBr).
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).
The examples of decomposition reactions are: 2NO -> N2 + O2 2KBr -> 2K + Br2 H2 + Cl2 -> 2HCl
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.
KCl: 2K(s) + Cl2(g) -> 2KCl(s) Br2: Br2(l) -> 2Br(s)
The balanced equation for the thermal decomposition of potassium nitrate is: 2 KNO3 (s) → 2 KNO2 (s) + O2 (g)
The coefficient for H2O is 1 in the balanced equation: 2K + 2H2O + 2KOH + H2
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and potassium (K) is: 2HCl + 2K -> 2KCl + H2.
(2k + 3) (2k + 3)
The balanced equation is 2K + 2H2O -> 2KOH + H2, balancing the atoms on both sides of the equation.
8k +2k + 7 = 10k + 7
