Question

с какими из перечисленных веществ: вода, цинк, медь, оксид кальция, гидроксид натрия, N2СО3, СО2 , С; будут реагировать: 1) азотная кислота; 2) оксид кремния; 3)фосфорная кислота; 4)кремниевая кислота; 5) оксид С (IV) 6)серная кислота; 7) оскид серы (VI) 8) соляная кислота

Answer 1

что за N2CO3? это уже органикой попахивает)

1.азотка реагирует с цинком, медью - продукты зависят от того разбавленная или концетрированная. с CaO - Ca(No3)2+H2O

2.оксид кремния с водой, оксидом кальция

 

Answer 2

Reactivity of Substances with Listed Compounds

1) Nitric acid (HNO3): Nitric acid is a strong acid and can react with various substances. It can react with water to produce nitrate ions (NO3-) and hydronium ions (H3O+). It can also react with metals like zinc and copper to form metal nitrates and release hydrogen gas [[1]].

2) Silicon dioxide (SiO2): Silicon dioxide, also known as silica, is a covalent compound and is generally unreactive with most acids and bases. However, it can react with strong bases like sodium hydroxide (NaOH) to form sodium silicate (Na2SiO3) [[2]].

3) Phosphoric acid (H3PO4): Phosphoric acid is a weak acid and can react with various substances. It can react with metals like zinc and copper to form metal phosphates and release hydrogen gas. It can also react with bases like sodium hydroxide to form sodium phosphate [[3]].

4) Silicic acid (H4SiO4): Silicic acid is a weak acid and can react with strong bases like sodium hydroxide to form sodium silicate [[4]].

5) Carbon dioxide (CO2): Carbon dioxide is a non-reactive gas under normal conditions. It is generally unreactive with most acids and bases. However, it can react with water to form carbonic acid (H2CO3) [[5]].

6) Sulfuric acid (H2SO4): Sulfuric acid is a strong acid and can react with various substances. It can react with metals like zinc and copper to form metal sulfates and release hydrogen gas. It can also react with bases like sodium hydroxide to form sodium sulfate [[6]].

7) Sulfur trioxide (SO3): Sulfur trioxide is a highly reactive compound and can react with water to form sulfuric acid. This reaction is highly exothermic and can release a large amount of heat [[7]].

8) Hydrochloric acid (HCl): Hydrochloric acid is a strong acid and can react with various substances. It can react with metals like zinc and copper to form metal chlorides and release hydrogen gas. It can also react with bases like sodium hydroxide to form sodium chloride [[8]].

Please note that the reactivity of substances can vary depending on the specific conditions and concentrations of the reactants involved.
