Question

4. Na2O + H2O = _NaOH 5. — С+ 0, = — СО9. — К+ СІ, = _КСІ10. — Fe(OH), = Fe,0, + — но​

Answer 1

Ответ:

Объяснение:

Na2O + H2O = 2NaOH

2C + O2 = 2CO

2K + Cl2 = 2KCl

2Fe(OH)3 = Fe2O3 + 3H2O

Answer 2

It looks like you've provided a list of chemical reactions and equations. I'll help you balance these chemical equations:

4. Na₂O + H₂O → 2NaOH

5. C + O₂ → CO₂

6. KCl + AgNO₃ → AgCl + KNO₃

7. Fe(OH)₃ → Fe₂O₃ + 3H₂O

Please note that in chemical equations, coefficients are used to balance the number of atoms on both sides of the equation, ensuring that the law of conservation of mass is upheld.
