Question

1)H2O+K2CO3-->   2)HCl+NaOH-->   3)H2SO4+CaCl2--->   4)H2SO4-->MgCl2-->   ответы пожалуйста с коэфицентами раставлеными:)

Answer 1

1) H2O + K2CO3 -> 2KOH + CO2 2) HCl + NaOH -> NaCl + H2O 3) H2SO4 + CaCl2 -> CaSO4 + 2HCl 4) H2SO4 + MgCl2 -> MgSO4 + 2HCl

1) H2O + K2CO3 -> 2KOH + CO2 - Water (H2O) reacts with potassium carbonate (K2CO3) to produce potassium hydroxide (KOH) and carbon dioxide (CO2) [[1]].

2) HCl + NaOH -> NaCl + H2O - Hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) to produce sodium chloride (NaCl) and water (H2O) [[2]].

3) H2SO4 + CaCl2 -> CaSO4 + 2HCl - Sulfuric acid (H2SO4) reacts with calcium chloride (CaCl2) to produce calcium sulfate (CaSO4) and hydrochloric acid (HCl) [[3]].

4) H2SO4 + MgCl2 -> MgSO4 + 2HCl - Sulfuric acid (H2SO4) reacts with magnesium chloride (MgCl2) to produce magnesium sulfate (MgSO4) and hydrochloric acid (HCl) [[4]].

Please note that the coefficients in the balanced chemical equations represent the stoichiometric ratios of the reactants and products.
