Question

4) KNO3 (разб.) +H2SO4(разб.) →; 5) NaCl(тв.) + H2SO4(конц.) →;​

Answer 1

Ответ:

Объяснение:

KNO3 (разб.) + H2SO4(разб.) → KHSO4  + HNO

NaCl(тверд.) + H2SO4(конц.) = NaHSO4 + HCl↑.

Answer 2

Ответ:

Объяснение:

2KNO₃(разб.)  + H₂SO₄ (разб.) = K₂SO₄ + 2HNO₃

NaCl(тв.) + H₂SO₄(конц.) = NaHSO₄ + HCl↑

Answer 3

4) KNO3 (разб.) + H2SO4 (разб.) → When potassium nitrate (KNO3) is dissolved in sulfuric acid (H2SO4), it undergoes a reaction. The reaction between KNO3 and H2SO4 produces nitric acid (HNO3) and potassium hydrogen sulfate (KHSO4) as products. The balanced chemical equation for this reaction is:

2 KNO3 (aq) + H2SO4 (aq) → 2 HNO3 (aq) + K2SO4 (aq)

In this reaction, two moles of potassium nitrate react with one mole of sulfuric acid to produce two moles of nitric acid and one mole of potassium sulfate.

5) NaCl (тв.) + H2SO4 (конц.) → When solid sodium chloride (NaCl) is added to concentrated sulfuric acid (H2SO4), a reaction occurs. The reaction between NaCl and H2SO4 produces hydrogen chloride gas (HCl) and sodium hydrogen sulfate (NaHSO4) as products. The balanced chemical equation for this reaction is:

2 NaCl (s) + H2SO4 (l) → 2 HCl (g) + Na2SO4 (s)

In this reaction, two moles of sodium chloride react with one mole of sulfuric acid to produce two moles of hydrogen chloride gas and one mole of sodium sulfate.

Please note that these reactions involve strong acids and should be performed with caution in a controlled laboratory setting.
