299 H2SO4 + 10 K4Fe(CN)6 + 122 KMnO4 = 60 CO2 + 5 Fe2(SO4)3 + 188 H2O + 60 HNO3 + 162 KHSO4 + 122MnSO4
To balance the equation SO2 + H2S = S + H2O, we need to ensure that there are equal numbers of each type of atom on both sides of the equation. Begin by placing coefficients in front of the compounds to balance the number of sulfur and hydrogen atoms, then balance the oxygen atoms last by adjusting the coefficient for H2O. The balanced equation is SO2 + 2 H2S = 3 S + 2 H2O.
To balance the chemical equation CaO + SO2 → CaSO3, you need to add a coefficient of 1 in front of CaO and SO2. This balances the equation by ensuring that the same number of each type of atom is present on both sides.
Ca + Br2 = CaBr2 doesn't need to be balanced.
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.
To balance the equation, you need 2 molecules of HCN on the reactant side. This will give you the balanced equation: NaCN + H2SO4 -> Na2SO4 + 2HCN.

C2h2+3o2=2c02+2h2o+2c
If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
Type your answer here... The ratio of the substances' coefficients equals the ratio of their number of moles.
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 is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
