Question

Выбрать электролиты Na2O,HNO3,Be(OH)2,Ca(HS)2,Na2CO3

Answer 1

HNO3,Be(OH)2,Na2CO3
Электролиты это кислоты,основания,и соли ) 

Answer 2

Electrolytes:

1. Na2O: Sodium oxide (Na2O) is an ionic compound that can dissociate into sodium ions (Na+) and oxide ions (O2-) when dissolved in water. Therefore, Na2O can act as an electrolyte in aqueous solutions.

2. HNO3: Nitric acid (HNO3) is a strong acid that dissociates completely into hydrogen ions (H+) and nitrate ions (NO3-) when dissolved in water. As a result, HNO3 is a strong electrolyte.

3. Be(OH)2: Beryllium hydroxide (Be(OH)2) is a weak base that partially dissociates into beryllium ions (Be2+) and hydroxide ions (OH-) when dissolved in water. Therefore, Be(OH)2 can act as a weak electrolyte.

4. Ca(HS)2: Calcium bisulfide (Ca(HS)2) is an ionic compound that can dissociate into calcium ions (Ca2+) and bisulfide ions (HS-) when dissolved in water. Thus, Ca(HS)2 can act as an electrolyte in aqueous solutions.

5. Na2CO3: Sodium carbonate (Na2CO3) is an ionic compound that can dissociate into sodium ions (Na+) and carbonate ions (CO3^2-) when dissolved in water. Therefore, Na2CO3 can act as an electrolyte in aqueous solutions.
