Question

Be➡️BeO➡️Be(NO3)2➡️Be(OH)2⬇️➡️Na2[Be(OH) 4] (T⬆️) ➡️Na2BeO2

Answer 1

Ответ:

1)2Be+O2⇒2BeO

2)BeO+2HNO3⇒Be(NO)2+H2O

3)Be(NO3)2+2NaOH⇒2NaNO3+Be(OH)2↓

4)Be(OH)2+2NaOH⇒Na2║Be(OH)4║

5)2Na2║Be(OH)4║⇒Na2BeO2+2NaOH+Be(OH)2+2H2↑(Ну это не точно:)

Answer 2

The series of chemical reactions you've described involve beryllium (Be) and its compounds. Let's go through each step:

1. Be: This is elemental beryllium, which is the starting material.

2. BeO (Beryllium Oxide): Beryllium reacts with oxygen to form beryllium oxide, BeO.

3. Be(NO3)2 (Beryllium Nitrate): Beryllium oxide can react with nitric acid (HNO3) to form beryllium nitrate, Be(NO3)2.

4. Be(OH)2 (Beryllium Hydroxide): Beryllium nitrate can react with a base, like sodium hydroxide (NaOH), to form beryllium hydroxide, Be(OH)2.

5. Na2[Be(OH)4] (Sodium Tetrahydroxoberyllate): Beryllium hydroxide can further react with sodium hydroxide to form sodium tetrahydroxoberyllate, Na2[Be(OH)4]. The upward arrow (↑) indicates that heat or some form of energy is needed for this reaction to occur.

6. Na2BeO2 (Sodium Beryllate): Finally, sodium tetrahydroxoberyllate can undergo further reactions to produce sodium beryllate, Na2BeO2.

It's important to note that beryllium and its compounds can be hazardous, and working with them should be done with proper safety precautions and under controlled conditions due to their toxic nature. Also, the reactions described here are simplified and may involve multiple steps and intermediate compounds in a real laboratory setting.
