Question

Составьте уравнения химических реакций: SO3 + H2O → MgO + HBr → H2SO4 + KOH → NaOH + CO2 → Cu(OH)2 → нагр.

Answer 1

Объяснение:

1) H2So4

2) MgO + 2 HBr → MgBr2 + H2O

3) 2KOH + H2SO4 → K2SO4 + 2H2O

4) 2NaOH + CO2 → Na2CO3 + H2O

5) CuO H2O

Answer 2

Chemical Equations:

1. Sulfur Trioxide and Water Reaction: - The chemical equation for the reaction between sulfur trioxide and water is: ``` SO3 + H2O → H2SO4 ``` [[Source 1]]

2. Magnesium Oxide and Hydrobromic Acid Reaction: - The chemical equation for the reaction between magnesium oxide and hydrobromic acid is: ``` MgO + 2HBr → MgBr2 + H2O ``` [[Source 2]]

3. Potassium Hydroxide and Sodium Hydroxide Reaction: - There is no direct chemical reaction between potassium hydroxide and sodium hydroxide. These two compounds do not react with each other under normal conditions.

4. Carbon Dioxide and Copper(II) Hydroxide Reaction: - The chemical equation for the reaction between carbon dioxide and copper(II) hydroxide is: ``` CO2 + Cu(OH)2 → CuCO3 + H2O ``` - Upon heating (denoted by "нагр."), copper(II) carbonate decomposes to form copper(II) oxide and carbon dioxide: ``` CuCO3 → CuO + CO2 ``` [[Source 3]]
