Question

решите , пожалуйста : PbSO4+BaCl2 = ? K2CO3+HCl= ? NH4NO3 + NaOH = ?

Answer 1

1)PbSO4 + BaCl2=BaSO4 + PbCl2

2)K2CO3+HCl=KCl + CO2 + H2O

3)NH4NO3 + NaOH=NaNO3+NH3 (тут нарисуй стрелку вверх- это газ) +H2O

 

Answer 2

PbSO4 + BaCl2 = ?

The reaction between lead(II) sulfate (PbSO4) and barium chloride (BaCl2) can be represented by the following balanced chemical equation:

PbSO4 + BaCl2 → PbCl2 + BaSO4

In this reaction, lead(II) sulfate reacts with barium chloride to form lead(II) chloride and barium sulfate.

K2CO3 + HCl = ?

The reaction between potassium carbonate (K2CO3) and hydrochloric acid (HCl) can be represented by the following balanced chemical equation:

K2CO3 + 2HCl → 2KCl + H2O + CO2

In this reaction, potassium carbonate reacts with hydrochloric acid to form potassium chloride, water, and carbon dioxide.

NH4NO3 + NaOH = ?

The reaction between ammonium nitrate (NH4NO3) and sodium hydroxide (NaOH) can be represented by the following balanced chemical equation:

NH4NO3 + NaOH → NH3 + H2O + NaNO3

In this reaction, ammonium nitrate reacts with sodium hydroxide to form ammonia, water, and sodium nitrate.
