2K+2HCl-->2KCl+H2
The reaction between K₂S and HCl forms KCl and H₂S gas. The balanced chemical equation is: K₂S + 2HCl → 2KCl + H₂S.
I believe it is already balanced. No coefficients neccessary
Balanced :2 K + 2 H2O ----> 2 KOH + H2
There is no reaction, because all product ( if reaction goes) would be soluble. so : H+ + Cl- + K+ + I- = H+ + Cl- + K+ + I- and than all of them dare present as a ions only.

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
To balance the equation involving KMnO₄ and MgS, we first need to identify the correct stoichiometric coefficients for each compound. The balanced equation will have coefficients that maintain the same number of each type of atom on both sides. The correct coefficients are 2 for KMnO₄, 1 for MgS, 2 for K₂S, and 1 for Mg(MnO₄)₂. Thus, the balanced equation is: 2 KMnO₄ + MgS → K₂S + Mg(MnO₄)₂.
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).
Balanced equation: 2 H2 + O2 --> 2 H2O
k equals 5.6
