Question

H2O->H2->HCl->AlCl3->AgCl

Answer 1

1) 2Н2O + 2Na = 2NaOH + H2
2) H2 + Cl2 = 2HCl
3) 6HCl + 2Al = 2AlCl3 + 3H2
4) AlCl3 + 3AgNO3 = Al(NO3)3 + 3AgCl

Answer 2

Chemical Reaction: H2O -> H2 -> HCl -> AlCl3 -> AgCl

The given chemical reaction sequence is as follows: H2O -> H2 -> HCl -> AlCl3 -> AgCl.

Let's break down the reaction step by step:

1. H2O -> H2: - This reaction represents the decomposition of water (H2O) into hydrogen gas (H2). - The balanced equation for this reaction is: 2H2O -> 2H2 + O2. - However, the given reaction only shows the formation of hydrogen gas (H2) from water (H2O).

2. H2 -> HCl: - This reaction represents the combination of hydrogen gas (H2) with chlorine gas (Cl2) to form hydrogen chloride gas (HCl). - The balanced equation for this reaction is: H2 + Cl2 -> 2HCl. - However, the given reaction only shows the formation of hydrogen chloride gas (HCl) from hydrogen gas (H2).

3. HCl -> AlCl3: - This reaction represents the reaction between hydrogen chloride gas (HCl) and aluminum hydroxide (Al(OH)3) to form aluminum chloride (AlCl3). - The balanced equation for this reaction is: 3HCl + Al(OH)3 -> AlCl3 + 3H2O. - However, the given reaction only shows the formation of aluminum chloride (AlCl3) from hydrogen chloride gas (HCl).

4. AlCl3 -> AgCl: - This reaction represents the reaction between aluminum chloride (AlCl3) and silver nitrate (AgNO3) to form silver chloride (AgCl) and aluminum nitrate (Al(NO3)3). - The balanced equation for this reaction is: 3AgNO3 + AlCl3 -> 3AgCl + Al(NO3)3. - However, the given reaction only shows the formation of silver chloride (AgCl) from aluminum chloride (AlCl3).

It's important to note that the given reaction sequence is not a complete representation of the chemical reactions involved. The reactions mentioned above are the balanced equations for the respective reactions.
