I believe it is already balanced. No coefficients neccessary
Balanced :2 K + 2 H2O ----> 2 KOH + H2
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and potassium (K) is: 2HCl + 2K -> 2KCl + H2.
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1
The balanced chemical equation for potassium bromide is KBr(s) --> K+(aq) + Br-(aq).

Yes, the equation K + Br2 = KBr is a balanced chemical equation. For example, 2 K + Br2 = 2 KBr is one and another balance chemical equation is Fe + Cl2 = FeCl3.
The balanced chemical equation for potassium bromide is KBr(s) --> K+(aq) + Br-(aq).
k equals 5.6
Balanced equation: 2 H2 + O2 --> 2 H2O
The reaction between K₂S and HCl forms KCl and H₂S gas. The balanced chemical equation is: K₂S + 2HCl → 2KCl + H₂S.
To balance the equation K + Br₂ → KBr, you need to make sure the number of atoms of each element is the same on both sides of the equation. To balance this equation, you need to put a coefficient of 2 in front of KBr. This way, you will have 2 potassium atoms, 2 bromine atoms, and 2 KBr molecules on both sides of the equation.
The balanced equation for the reaction between borax (sodium borate) and sulfuric acid is: Na2B4O7·10H2O + 4H2SO4 → 4H3BO3 + 2Na2SO4 + 5H2O.
The balanced chemical equation for the reaction between potassium (K) and sulfuric acid (H2SO4) to form potassium sulfate (K2SO4) and hydrogen gas (H2) is: 2K + H2SO4 -> K2SO4 + H2
