The balanced chemical equation for this reaction is 2HBr (aq) + 2NaOH (aq) → 2H2O (l) + 2NaBr (aq). This balanced equation represents the reaction between hydrobromic acid and sodium hydroxide to produce water and sodium bromide. Each side of the equation has the same number of atoms for each element.

Hydrobromic acid
Hydrogen gas is formed when aluminum metal reacts with aqueous sodium hydroxide. The reaction produces aluminum hydroxide and hydrogen gas.
When aqueous potassium hydroxide is reacted with sulfur dioxide, potassium sulfite (K2SO3) and water are produced. The balanced chemical equation for the reaction is: 2KOH + SO2 → K2SO3 + H2O.
The reaction between aqueous sodium nitrate, sodium hydroxide, and aluminum foil produces hydrogen gas. This is because aluminum reduces sodium ions to sodium metal, which releases hydrogen gas in the presence of water and sodium hydroxide.
The reaction between sodium hydroxide and sulfuric acid produces sodium sulfate and water. Sodium hydroxide (NaOH) reacts with sulfuric acid (H2SO4) in a neutralization reaction to form sodium sulfate (Na2SO4) and water (H2O).
The reaction between dissolved sodium hydroxide and aqueous hydrogen sulfate forms aqueous sodium sulfate and water vapor. This is a neutralization reaction where sodium hydroxide and hydrogen sulfate ions combine to form sodium sulfate and water. The balanced chemical equation for this reaction is 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
The products of the double-replacement reaction between aqueous hydrogen bromide and aqueous sodium hydroxide are water and sodium bromide. The hydrogen ion from HBr combines with the hydroxide ion from NaOH to form water, while the sodium ion from NaOH combines with the bromide ion from HBr to form sodium bromide.
The net ionic equation for the reaction between hydrobromic acid (HBr) and ammonia (NH3) is: H+ + NH3 -> NH4+. This represents the formation of ammonium ion (NH4+) when ammonia accepts a proton from hydrobromic acid.
The reaction between aqueous nitric acid (HNO3) and aqueous calcium hydroxide (Ca(OH)2) forms water (H2O) and aqueous calcium nitrate [Ca(NO3)2]. This is a double displacement reaction where the positive ions switch partners to form the products.
When aqueous ammonia is added to lime water, a white precipitate of calcium hydroxide is formed as the ammonia reacts with the calcium hydroxide present in the lime water. This reaction can be represented as: Ca(OH)2 + 2NH3 → Ca(NH2)2 + 2H2O.
