Answer 2

1) Na H3PO4: The reaction between sodium phosphate (NaH3PO4) can be written as follows: NaH3PO4 + H2O -> H3PO4 + NaOH In this reaction, sodium phosphate reacts with water to form phosphoric acid (H3PO4) and sodium hydroxide (NaOH) [[1]].

2) CaCO + HCl: The reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl) can be written as follows: CaCO3 + 2HCl -> CaCl2 + H2O + CO2 In this reaction, calcium carbonate reacts with hydrochloric acid to form calcium chloride (CaCl2), water (H2O), and carbon dioxide (CO2) [[2]].

3) NaOH + H2SiO3: The reaction between sodium hydroxide (NaOH) and silicic acid (H2SiO3) can be written as follows: 2NaOH + H2SiO3 -> Na2SiO3 + 2H2O In this reaction, sodium hydroxide reacts with silicic acid to form sodium silicate (Na2SiO3) and water (H2O) [[3]].

4) MgO + HBr: The reaction between magnesium oxide (MgO) and hydrobromic acid (HBr) can be written as follows: MgO + 2HBr -> MgBr2 + H2O In this reaction, magnesium oxide reacts with hydrobromic acid to form magnesium bromide (MgBr2) and water (H2O) [[4]].

5) Mn + H2SO4: The reaction between manganese (Mn) and sulfuric acid (H2SO4) can be written as follows: Mn + H2SO4 -> MnSO4 + H2 In this reaction, manganese reacts with sulfuric acid to form manganese sulfate (MnSO4) and hydrogen gas (H2) [[5]].

6) Fe(OH)3 + HCl: The reaction between iron(III) hydroxide (Fe(OH)3) and hydrochloric acid (HCl) can be written as follows: Fe(OH)3 + 3HCl -> FeCl3 + 3H2O In this reaction, iron(III) hydroxide reacts with hydrochloric acid to form iron(III) chloride (FeCl3) and water (H2O) [[6]].

7) Na2CO3 + HNO3: The reaction between sodium carbonate (Na2CO3) and nitric acid (HNO3) can be written as follows: 2Na2CO3 + 2HNO3 -> 2NaNO3 + H2O + CO2 In this reaction, sodium carbonate reacts with nitric acid to form sodium nitrate (NaNO3), water (H2O), and carbon dioxide (CO2) [[7]].

8) CaO + H2S: The reaction between calcium oxide (CaO) and hydrogen sulfide (H2S) can be written as follows: CaO + H2S -> CaS + H2O In this reaction, calcium oxide reacts with hydrogen sulfide to form calcium sulfide (CaS) and water (H2O) [[8]].
