Answer 2

Reaction 1: K2SiO3 + H2SO4 -> CaO + HNO3

The reaction between potassium silicate (K2SiO3) and sulfuric acid (H2SO4) produces calcium oxide (CaO) and nitric acid (HNO3).

Potassium silicate (K2SiO3) is a compound composed of potassium ions (K+) and silicate ions (SiO3^2-). Sulfuric acid (H2SO4) is a strong acid composed of hydrogen ions (H+) and sulfate ions (SO4^2-).

When potassium silicate reacts with sulfuric acid, the potassium ions (K+) from potassium silicate combine with the sulfate ions (SO4^2-) from sulfuric acid to form potassium sulfate (K2SO4). The silicate ions (SiO3^2-) from potassium silicate combine with the hydrogen ions (H+) from sulfuric acid to form water (H2O). The balanced equation for this reaction is:

2K2SiO3 + H2SO4 -> K2SO4 + H2O + SiO2

The reaction between calcium oxide (CaO) and nitric acid (HNO3) produces calcium nitrate (Ca(NO3)2) and water (H2O). The balanced equation for this reaction is:

CaO + 2HNO3 -> Ca(NO3)2 + H2O

Reaction 2: CaO + HNO3 -> Zn(OH)2 + HCl

The reaction between calcium oxide (CaO) and nitric acid (HNO3) produces zinc hydroxide (Zn(OH)2) and hydrochloric acid (HCl).

When calcium oxide reacts with nitric acid, calcium nitrate (Ca(NO3)2) and water (H2O) are formed. The balanced equation for this reaction is:

CaO + 2HNO3 -> Ca(NO3)2 + H2O

Zinc hydroxide is formed when zinc ions (Zn^2+) from zinc nitrate (Zn(NO3)2) react with hydroxide ions (OH-) from water. The balanced equation for this reaction is:

Zn(NO3)2 + 2H2O -> Zn(OH)2 + 2HNO3

Hydrochloric acid is formed when hydrogen ions (H+) from nitric acid react with chloride ions (Cl-) from zinc chloride (ZnCl2). The balanced equation for this reaction is:

2HNO3 + ZnCl2 -> 2HCl + Zn(NO3)2

Therefore, the overall balanced equation for the reaction between calcium oxide (CaO) and nitric acid (HNO3) is:

CaO + 2HNO3 -> Zn(OH)2 + 2HCl
