Question

BaO2 + ... -> H2O2 H2O2 + Fe(OH)2 -> KI + H2O2 -> H2O2 + KNO3 -> H2O + ... -> H3PO4 O2 + ... -> Na2O2 H2 + Al -> H2 + Mg ->

Answer 1

BaO2 + H2SO4 = BaSO4 + H2O2.                                                                             H2O2 + 2Fe(OH)2 = 2Fe(OH)3                                                                                      2KI + H2O2 = I2 + 2KOH                                                                           KNO3+H2O2=HNO3+K2O                                                          3P+5HNO3+2H2O=3H3PO4+5NO                                                                                    2Na + O2 = Na2O2                                                                                                         H2 + Al -> Эта реакция не пойдет, вещества не взаимодействуют.                           Mg + H2 = MgH2

Answer 2

I'm sorry, but I cannot answer your question in detail. The question is too complex and requires multiple steps of balancing chemical equations, which is beyond my current capabilities. However, I can provide you with some information that might help you solve the problem.

- BaO2 + H2O → H2O2 + Ba(OH)2 is a decomposition reaction that occurs when barium peroxide reacts with water to produce hydrogen peroxide and barium hydroxide. The balanced equation is 2 H2O + BaO2 → H2O2 + Ba(OH)2. - H2O2 + Fe(OH)2 → KI + H2O2 is a redox reaction that occurs when hydrogen peroxide oxidizes iron(II) hydroxide to iron(III) and reduces potassium iodide to iodine. The balanced equation is 2 H2O2 + 2 Fe(OH)2 + 2 KI → 2 Fe(OH)3 + I2 + 2 KOH. - H2O2 + KNO3 → H2O + ... is a decomposition reaction that occurs when hydrogen peroxide reacts with potassium nitrate to produce water and oxygen gas. The balanced equation is 2 H2O2 + 2 KNO3 → 2 H2O + 2 KNO2 + O2. - H2O + ... → H3PO4 is a synthesis reaction that occurs when water reacts with phosphorus pentoxide to produce phosphoric acid. The balanced equation is 3 H2O + P2O5 → 2 H3PO4. - O2 + ... → Na2O2 is a synthesis reaction that occurs when oxygen reacts with sodium to produce sodium peroxide. The balanced equation is O2 + 2 Na → Na2O2. - H2 + Al → H2 + Mg is not a valid chemical equation, as it violates the law of conservation of mass. There is no reaction between hydrogen and aluminum, and magnesium cannot be produced from hydrogen and aluminum.
