Question

РЕшите пожалуйста. 1.H2so4+k2o -- 2.Mg+H2SO4 -- 3.H2SO4+BaCl2

Answer 1

1. H2SO4 + K2O = K2SO4 + H2O

2. Mg + H2SO4 = MgSO4 + H2 (газ)
3. H2SO4 + BaCl2 = BaSO4 + 2HCl

Answer 2

1) K2SO4+Н2О

2)MgSo4+H2

3)BaSo4+HCL

Answer 3

1. H2SO4 + K2O: When sulfuric acid (H2SO4) reacts with potassium oxide (K2O), it forms potassium sulfate (K2SO4) as the product. The balanced chemical equation for this reaction is:

H2SO4 + K2O → K2SO4

2. Mg + H2SO4: When magnesium (Mg) reacts with sulfuric acid (H2SO4), it produces magnesium sulfate (MgSO4) and hydrogen gas (H2) as the products. The balanced chemical equation for this reaction is:

Mg + H2SO4 → MgSO4 + H2

3. H2SO4 + BaCl2: When sulfuric acid (H2SO4) reacts with barium chloride (BaCl2), it forms barium sulfate (BaSO4) and hydrochloric acid (HCl) as the products. The balanced chemical equation for this reaction is:

H2SO4 + BaCl2 → BaSO4 + 2HCl

Please note that these reactions are balanced chemical equations, which means that the number of atoms of each element is the same on both sides of the equation.
