| May 6, 2021 | education

The reaction takes place between substances such as calcium carbonate salt and nitric acid. Formed salt calcium nitrate and carbonic acid, which under normal conditions decomposes into water and carbon dioxide. Graphically, this equation of a chemical reaction can be expressed as follows:

CaCO3 + 2 HNO3 = Ca (NO3) 2 + CO2 + H2O
Sodium hydroxide reacts with nitric acid and, as a result of the substitution reaction, the sodium nitrate salt is formed and water is released. The molecular equation of the reaction can be written as follows:

NaOH + HNO3 = NaNO3 + H2O
The reaction takes place between substances such as zinc oxide and nitric acid. Zinc nitrate salt is formed and water is released. Graphically, this equation of a chemical reaction can be expressed as follows:

ZnO + 2 HNO3 = Zn (NO3) 2 + H2O
Copper reacts with nitric acid. As a result of chemical interaction, copper nitrate salt, nitric oxide and water are formed. Graphically, this equation of a chemical reaction can be expressed as follows:

3 Cu + 8 HNO3 = 3 Cu (NO3) 2 + 2 NO + 4 H2O.
