Question

Закончить уравнение реакций. расставить коэффициенты. определить тип реакции. дать названия всем веществам SO2+H2O=? BaO+H2O=? Mg+H2SO4=? Na2So3+ZnCl2=?

Answer 1

1)SO2 + H2O→← H2SO3- реакция соединения
"→←"- это означает, что реакция обратима.

2)BaO+ H2O→ Ba(OH)2- реакция соединения

3) Mg+ H2SO4→ MgSO4+H2-реакция замещения

4) Na2SO3+ZnCl2→ 2NaCl+ ZnSO3- реакция обмена

Answer 2

Balancing Chemical Equations

Balancing the Equations:

1. SO2 + H2O = ? - The balanced equation for the reaction of sulfur dioxide (SO2) with water (H2O) is: ``` SO2 + H2O = H2SO3 ``` - The coefficients are: 1, 1, 1 2. BaO + H2O = ? - The balanced equation for the reaction of barium oxide (BaO) with water (H2O) is: ``` BaO + H2O = Ba(OH)2 ``` - The coefficients are: 1, 2, 1 3. Mg + H2SO4 = ? - The balanced equation for the reaction of magnesium (Mg) with sulfuric acid (H2SO4) is: ``` Mg + H2SO4 = MgSO4 + H2 ``` - The coefficients are: 1, 1, 1, 1 4. Na2SO3 + ZnCl2 = ? - The balanced equation for the reaction of sodium sulfite (Na2SO3) with zinc chloride (ZnCl2) is: ``` Na2SO3 + ZnCl2 = ZnSO3 + 2NaCl ``` - The coefficients are: 1, 1, 1, 2

Types of Reactions:

- SO2 + H2O = H2SO3 represents a chemical reaction known as a neutralization reaction. - BaO + H2O = Ba(OH)2 represents a chemical reaction known as a base-metal oxide reaction. - Mg + H2SO4 = MgSO4 + H2 represents a chemical reaction known as a single displacement reaction. - Na2SO3 + ZnCl2 = ZnSO3 + 2NaCl represents a chemical reaction known as a double displacement reaction.

These are the balanced equations and the types of reactions for the given chemical reactions. If you have any more questions or need further assistance, feel free to ask!
