What is it about these three questions that you don't understand? You're asking us to do your homework and few here will do that.

Did you know?

Did you know that light has a significant effect on elements such as sodium, potassium, lithium, rubidium, and caesium? When exposed to light, these elements can undergo interesting reactions and changes in their properties. For example, sodium reacts explosively with water when exposed to light, while caesium is known to emit a faint blue glow when illuminated. This highlights the fascinating ways in which light interacts with matter and contributes to various chemical phenomena. Did you know that you can design an experiment to prepare or precipitate silver halides? One common method involves mixing a soluble silver salt, like silver nitrate, with a halide salt, such as sodium chloride or potassium iodide. This combination results in the formation of insoluble silver halides, like silver chloride or silver iodide, which precipitate out of solution. This experiment can help students understand the principles of precipitation reactions and the formation of solid compounds. Did you know that an investigation of light on silver halides can yield interesting results? When light interacts with silver halides, it can trigger a phenomenon known as photochemical decomposition. This means that the light can break down the silver halide compound, leading to a change in color or even the release of silver ions. This investigation can provide insights into the role of light in chemical reactions and the impact of different wavelengths on the decomposition process.
