### Decomposition of Hydrobromic Acid (HBr)The compound HBr (hydrobromic acid) can be decomposed to form hydrogen gas (H₂) and bromine gas (Br₂). This chemical reaction can be represented at the atomic level by the equation:\[ \mathbf{2HBr \rightarrow H_2 + Br_2} \]According to the law of conservation of mass, the mass of the reactants must equal the mass of the products. Given the scenario:- **Given Data:** - 31.7 grams of HBr decomposes. - 0.4 grams of H₂ is formed.- **Question:** - How many grams of Br₂ must simultaneously be formed?**Solution:**To determine the mass of Br₂ formed, consider the mass conservation principle:\[ \text{Mass of } HBr = \text{Mass of } H_2 + \text{Mass of } Br_2 \]From the given values:\[ 31.7 \text{ grams of } HBr = 0.4 \text{ grams of } H_2 + \text{Mass of } Br_2 \]Thus, the mass of Br₂ can be calculated as:\[ \text{Mass of } Br_2 = 31.7 \text{ grams} - 0.4 \text{ grams} \]\[ \text{Mass of } Br_2 = 31.3 \text{ grams} \]Therefore, the mass of Br₂ formed is:\[ \boxed{31.3} \text{ grams Br}_2 \]
