Question

Sn->SnO->Sn(No3)2->Sn(OH)2

Answer 1

Ответ:

1) 2Sn + O2 = 2SnO

2) SnO + 2HNO3 = Sn(NO3)2 + H2O

3) Sn(NO3)2 + 2NaOH = Sn(OH)2 + 2NaNO3

Answer 2

The sequence you've provided appears to be a series of chemical reactions involving tin (Sn) progressing from its elemental form to different chemical compounds. Let me explain each step of the sequence:

1. Sn (Tin): This represents elemental tin in its metallic form. Tin is a chemical element with the symbol Sn and atomic number 50.

2. SnO (Tin(II) oxide or stannous oxide): In this step, tin reacts with oxygen to form tin(II) oxide (SnO). The chemical equation for this reaction is:

   Sn + O2 -> SnO

3. Sn(NO3)2 (Tin(II) nitrate): Tin(II) oxide (SnO) can react with nitric acid (HNO3) to form tin(II) nitrate (Sn(NO3)2). The chemical equation for this reaction is:

   SnO + 2HNO3 -> Sn(NO3)2 + H2O

4. Sn(OH)2 (Tin(II) hydroxide): Tin(II) nitrate (Sn(NO3)2) can react with a base like sodium hydroxide (NaOH) to form tin(II) hydroxide (Sn(OH)2). The chemical equation for this reaction is:

   Sn(NO3)2 + 2NaOH -> Sn(OH)2 + 2NaNO3

So, the overall sequence of reactions is:

Sn -> SnO -> Sn(NO3)2 -> Sn(OH)2

These reactions show the transformation of elemental tin into tin(II) oxide, then into tin(II) nitrate, and finally into tin(II) hydroxide through a series of chemical reactions.
