Question

Na2CO3+HCIH2SO4+KOH-K2CO3+HC1-CuSO4+NaOH+FeC13+KOH-K2CO3+CO(NO3)2​

Answer 1

Ответ:

Na2CO3+2HCl-->2NaCl+CO2+H2O

H2SO4+2KOH-->K2SO4+2H2O

K2CO3+2HCl-->2KCl+CO2+H2O

CuSO4+2NaOH-->Na2SO4+Cu(OH)2

FECl3+3KOH-->Fe(OH)3+3KCl

Answer 2

It seems like you've provided a sequence of chemical reactions. I'll help you understand the reactions step by step:

1. Na2CO3 (Sodium carbonate) reacts with HCl (Hydrochloric acid): Na2CO3 + 2HCl → 2NaCl + H2O + CO2

2. The resulting products from the first reaction are NaCl (Sodium chloride), H2O (water), and CO2 (carbon dioxide).

3. NaCl (Sodium chloride) is not directly involved in the subsequent reactions, so we can ignore it for now.

4. CuSO4 (Copper sulfate) reacts with NaOH (Sodium hydroxide): CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4

5. The resulting products from the second reaction are Cu(OH)2 (Copper hydroxide) and Na2SO4 (Sodium sulfate).

6. FeCl3 (Iron(III) chloride) reacts with KOH (Potassium hydroxide): FeCl3 + 3KOH → Fe(OH)3 + 3KCl

7. The resulting products from the third reaction are Fe(OH)3 (Iron(III) hydroxide) and 3KCl (Potassium chloride).

It appears that you have three separate reactions, and the products from each reaction are different. If you want to know what happens in the subsequent reactions or if you have specific questions about any of the products formed, please provide more details, and I'll be happy to assist further.
