Question

H3PO4+K=H3PO4+K20=H3PO4+KOH=H3PO4+NA2CO3=

Answer 1

Ответ:

Объяснение:

2H3PO4  +  2K  =  2KH2PO4  +  H2↑

                           дигидрофосфат

                                  калия

H3PO4  +  K2О  =  K2HPO4  +  2H2О

                            гидрофосфат

                                 калия

H3PO4  +  KОН  =   KH2PO4  +  H2О

                          дигидрофосфат

                                  калия

    H3PO4  + Na2CO3  =  Na2HPO4  +  H2О  +  СО2

                                        гидрофосфат

                                              натрия                        

Answer 2

The chemical equations you provided appear to be incomplete or incorrect. Allow me to clarify:

1. H3PO4 + K: This equation represents the reaction between phosphoric acid (H3PO4) and potassium (K). However, it doesn't show a complete chemical reaction. Without further information, it is difficult to determine the specific products formed.

2. H3PO4 + K20: The notation "K20" is not a recognized chemical formula. It is likely a typographical error or a misunderstanding. Please provide the correct formula or information to assist you better.

3. H3PO4 + KOH: This equation represents the reaction between phosphoric acid (H3PO4) and potassium hydroxide (KOH). The balanced equation for this reaction is:

   H3PO4 + 3KOH → K3PO4 + 3H2O

   The products of this reaction are potassium phosphate (K3PO4) and water (H2O).

4. H3PO4 + NA2CO3: This equation represents the reaction between phosphoric acid (H3PO4) and sodium carbonate (Na2CO3). The balanced equation for this reaction is:

   2H3PO4 + 3Na2CO3 → Na3PO4 + 3H2O + 3CO2

   The products of this reaction are trisodium phosphate (Na3PO4), water (H2O), and carbon dioxide (CO2).

Please note that these equations represent balanced chemical reactions. The actual outcome may vary depending on the specific conditions and concentrations used in the reaction.
