Question

MgO+?→ Mg²+ + H₂O;H+ +?→H2O​

Answer 1

Ответ:

для того чтобы найти ? Надо посмотреть на продукты , там есть водород значит добавим

MgO+H2=Mg+H2O

а вторая реакция простая

H2+0.5 O2=H2O

Объяснение:

Answer 2

Based on the chemical equations you provided, it seems like you're asking for the missing reactants in each equation.

In the first equation: MgO + ? → Mg²+ + H₂O

MgO is a compound composed of magnesium (Mg) and oxygen (O). When it reacts, it forms magnesium ions (Mg²+) and water (H₂O). The missing reactant is water (H₂O). Therefore, the balanced equation would be:

MgO + H₂O → Mg²+ + H₂O

In the second equation: H+ + ? → H₂O

H+ represents a hydrogen ion, typically found in an acidic solution. When it reacts, it forms water (H₂O). The missing reactant is hydroxide (OH-). Therefore, the balanced equation would be:

H+ + OH- → H₂O
