Объяснение:

X - Calcium (Ca)

Y - Sulfur (S)

нижній ряд:

2CaS + 3O2 = 2CaO + 2SO2

CaO + 2HCl = CaCl2 + H2O

CaCl2 + 2H2O = Ca(OH)2 + 2HCl

Ca(OH)2 →(t)→ CaO + H2O

2CaO→(t)→ 2Ca+O2↑

середній ряд:

2CaS + 3O2 = 2CaO + 2SO2

2SO2 + O2 = 2SO3

SO3 + 2HNO3 = H2SO4 + N2O5

H2SO4 + 8HI = H2S + 4I2 + 4H2O

H2S + Cl2 = S + 2HCl

3S + 3Ca(OH)2 = 2CaS + CaSO3 + 3H2O

першій ряд:

SO2 + H2O = H2SO3

4H2SO3 + 2SO2 = 4H2SO4 + S2

H2SO4 + 8HI = H2S + 4I2 + 4H2O

2H2S + O2 = 2S + 2H2O
