Question

Складіть рівняння можливих реакцій між бромідною кислотою й такими речовинами: вода, хром, магній оксид, натрій гідроксид.​

Answer 1

Відповідь:

Br2+H2O <=> HBrO+ HBr (р-ція зворотня)

2Cr+3Br2—> 2CrBr3 (р-ці я проходить під дією температури t)

2MgO+2Br2 -–>2MgBr2+O2

3Br2 + 6NaOH —> 5NaBr + NaBrO3 + 3H2O (р-ція відбувається під дією температури t)

Answer 2

#### Possible Reactions between Hydrobromic Acid and Various Substances Hydrobromic acid (HBr) is a strong acid that can react with various substances to form different products. Let's explore the possible reactions between hydrobromic acid and water, chromium, magnesium oxide, and sodium hydroxide. 1. Reaction between Hydrobromic Acid and Water: - Hydrobromic acid can react with water in a reversible reaction to form hydronium ions (H3O+) and bromide ions (Br-). - The balanced chemical equation for this reaction is: **HBr + H2O ⇌ H3O+ + Br-**. 2. Reaction between Hydrobromic Acid and Chromium: - Hydrobromic acid can react with chromium to form chromium(III) bromide and hydrogen gas. - The balanced chemical equation for this reaction is: **2HBr + Cr → CrBr3 + H2**. 3. Reaction between Hydrobromic Acid and Magnesium Oxide: - Hydrobromic acid can react with magnesium oxide to form magnesium bromide and water. - The balanced chemical equation for this reaction is: **2HBr + MgO → MgBr2 + H2O**. 4. Reaction between Hydrobromic Acid and Sodium Hydroxide: - Hydrobromic acid can react with sodium hydroxide to form sodium bromide and water. - The balanced chemical equation for this reaction is: **HBr + NaOH → NaBr + H2O**. Please note that these reactions are theoretical and may require specific conditions (e.g., temperature, concentration) to occur. It is always important to conduct experiments or refer to reliable sources for accurate information on specific reactions. I hope this information is helpful!
