1. The variation of decomposition temperature, solubilities, and bond angle of group five hydrides:<br /> - Decomposition temperature: The decomposition temperature of group five hydrides varies depending on the specific compound. For example, phosphine (PH3) decomposes at a lower temperature compared to nitrogen hydride (NH3).<br /> - Solubilities: The solubility of group five hydrides in water also varies. For instance, ammonia (NH3) is highly soluble in water, while phosphine (PH3) is less soluble.<br /> - Bond angle: The bond angle in group five hydrides can vary depending on the specific compound. For example, the bond angle in ammonia (NH3) is approximately 107 degrees, while in phosphine (PH3), it is approximately 93 degrees.<br /><br />2. Anomalous behavior of Nitrogen and uses of Group five compounds:<br /> - Anomalous behavior of Nitrogen: Nitrogen exhibits anomalous behavior in its physical and chemical properties. For example, it exists as a diatomic molecule (N2) under normal conditions, and it has a very low reactivity compared to other non-metal elements.<br /> - Uses of Group five compounds: Group five compounds, such as nitrogen, phosphorus, and arsenic, have various applications. For example, ammonia (NH3) is used in the production of fertilizers, while phosphorus is used in the manufacture of matches and detergents.<br /><br />3. Using chemical equations to describe the extraction of Bismuth (Bi) from bismuthinite:<br /> - The extraction of bismuth from bismuthinite involves several steps, including roasting, leaching, and purification. The overall chemical equation for the extraction process can be represented as:<br /> 2Bi2O3 + 3C → 4Bi + 3CO2<br /><br />4. Reactions of sulfur with air and excess air, and the use of these products to react with water:<br /> - Reaction with air: When sulfur is burned in air, it reacts with oxygen to form sulfur dioxide (SO2). The chemical equation for this reaction is:<br /> S + O2 → SO2<br /> - Reaction with excess air: When sulfur is burned in excess air, it reacts with oxygen to form sulfur trioxide (SO3). The chemical equation for this reaction is:<br /> 2S + 3O2 → 2SO3<br /> - Use of products: Sulfur dioxide (SO2) and sulfur trioxide (SO3) can be used to react with water to form sulfuric acid (H2SO4). The chemical equations for these reactions are:<br /> SO2 + H2O → H2SO3<br /> SO3 + H2O → H2SO4<br /><br />5. Definition of in-halogen compounds and explanation of their five properties:<br /> - In-halogen compounds: In-halogen compounds are compounds that contain halogen atoms bonded to carbon atoms. Examples include chloroform (CHCl3) and bromoform (CHBr3).<br /> - Properties of in-halogen compounds:<br /> 1. Low reactivity: In-halogen compounds are generally less reactive compared to free halogens.<br /> 2. Low boiling points: In-halogen compounds typically have lower boiling points compared to their corresponding free halogens.<br /> 3. Solubility in organic solvents: In-halogen compounds are generally soluble in organic solvents but insoluble in water.<br /> 4. Odor: In-halogen compounds often have a distinct odor, depending on the specific compound.<br /> 5. Toxicity: Some in-halogen compounds, such as chloroform, are toxic and can have harmful effects on human health.<br /><br />6. Chemical reaction of halogen with water:<br /> - The reaction of a halogen with water depends on the specific halogen. For example, chlorine (Cl2) reacts with water to form hydrochloric acid (HCl) and hypochlorous acid (HOCl). The chemical equation for this reaction is:<br /> Cl2 + H2O → HCl + HOCl
