Accepted Answer
| Question: | Write its reaction with acid rain Calcium carbonate (CaCO3) + Combustion of carbon Carbon (C) + Why it is important Palladium (Pd) |
| Solution: | Calcium carbonate reacts with acid rain, and carbon undergoes combustion. Palladium plays a crucial role in catalysis. |
| Chemical Equation: | CaCOโ(s) + 2Hโบ(aq) โ Caยฒโบ(aq) + HโO(l) + COโ(g) 2C(s) + Oโ(g) โ 2CO(g) or C(s) + Oโ(g) โ COโ(g) |
| Explanation: | Acid rain, often containing sulfuric acid (HโSOโ) and nitric acid (HNOโ), reacts with calcium carbonate (limestone, marble etc.) ๐ชจ in a neutralization reaction, producing calcium ions, water, and carbon dioxide gas ๐จ. The combustion of carbon (C) ็็ง๐ฅ with oxygen (Oโ) produces either carbon monoxide (CO) or carbon dioxide (COโ), depending on the availability of oxygen. Palladium (Pd) ๐งช is important due to its catalytic properties, frequently used in various chemical reactions as a catalyst to speed them up ๐๏ธ without being consumed itself. It's crucial in various industrial processes and applications, including automotive catalytic converters ๐๐จ. |
