Question

1) K2CO3 + .... = CO22) CO2 + .... = Na2CO3​

Answer 1

Ответ:

Объяснение:

K2CO3 + 2HCl = 2KCl + CO2 + H2O

CO2 + Na2O = Na2CO3

Answer 2

1. K2CO3 + H2SO4 = CO2 + K2SO4 + H2O

When potassium carbonate (K2CO3) reacts with sulfuric acid (H2SO4), it forms carbon dioxide (CO2), potassium sulfate (K2SO4), and water (H2O). The balanced chemical equation for this reaction is:

K2CO3 + H2SO4 → CO2 + K2SO4 + H2O

2. CO2 + 2 NaOH = Na2CO3 + H2O

When carbon dioxide (CO2) reacts with sodium hydroxide (NaOH), it forms sodium carbonate (Na2CO3) and water (H2O). The balanced chemical equation for this reaction is:

CO2 + 2 NaOH → Na2CO3 + H2O
