Chemical Reaction Scheme

The given chemical reactions are as follows: 1) CaCO3 → CaO + CO2 2) Ba + O2 → BaO 3) K + S → K2S 4) Al(OH)3 → Al2O3 + H2O

The sum of coefficients for the reactions is to be determined.

Coefficients Sum Calculation

Let's calculate the sum of coefficients for the given chemical reactions.

1) For the reaction CaCO3 → CaO + CO2, the sum of coefficients is 3. 2) For the reaction Ba + O2 → BaO, the sum of coefficients is 2. 3) For the reaction K + S → K2S, the sum of coefficients is 2. 4) For the reaction Al(OH)3 → Al2O3 + H2O, the sum of coefficients is 4.

Therefore, the sum of coefficients for all the reactions is 3 + 2 + 2 + 4 = 11.

So, the correct answer is 11 (Б).
