Question

1)H2+Br2>HBr2)HClO3>HCl+O23)Na2+H2>NH34)K2+H20>KOH+H25)Ca+O2>CaO​

Answer 1

Ответ:

Br2 + H2 → 2HBr

2HClO3 → 2HCl + 3O2

Na2 + 3H2 → 2NaH3

K2 + 2H2O → 2KOH + H2

2Ca + O2 → 2CaO

Объяснение:

Answer 2

It looks like you've written a series of chemical reactions. I can help you balance these chemical equations:

1. H2 + Br2 -> 2HBr (Balanced: 1:1 ratio)
2. HClO3 -> HCl + O2 (Balanced: 1:1:3 ratio)
3. 2Na + H2 -> 2NaH (Balanced: 2:2 ratio)
4. K2 + H2O -> 2KOH + H2 (Balanced: 2:2:2 ratio)
5. 2Ca + O2 -> 2CaO (Balanced: 2:1 ratio)

These equations are now balanced, showing the correct stoichiometry of reactants and products. If you have any further questions or need more assistance, feel free to ask!
