1. The general chemical equation for the reaction between metals and acids to produce hydrogen gas is: Metal(s) + Acid(aq) ⟶ Metal Salt(aq) + Hydrogen Gas(g) This reaction involves the metal reacting with an acid to form a metal salt and release hydrogen gas.

    The general chemical equation for the reaction between metals and acids to produce hydrogen gas is:

    Metal(s) + Acid(aq) ⟶ Metal Salt(aq) + Hydrogen Gas(g)

    This reaction involves the metal reacting with an acid to form a metal salt and release hydrogen gas. The specific metal salt formed depends on the metal and acid involved in the reaction. For example, with hydrochloric acid, the metal chloride is formed, while sulfuric acid produces the corresponding metal sulfate. This type of reaction is a common way to generate hydrogen gas in the laboratory and is utilized in various chemical processes.

    The combustion of fuels like coal and petroleum releases various environmental pollutants. Carbon dioxide (CO2) is a major greenhouse gas contributing to climate change. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are emitted, leading to acid rain and air pollution. Particulate matter (PM), including soot and ash, poses respiratory health risks. Trace elements like mercury and heavy metals can contaminate ecosystems. Incomplete combustion generates carbon monoxide (CO), a poisonous gas. Additionally, volatile organic compounds (VOCs) contribute to smog formation. The environmental impact necessitates the development of cleaner energy sources and emission control technologies to mitigate these pollutants.

    Saturated hydrocarbons are generally unreactive due to the strength and stability of carbon-carbon single bonds. However, they undergo rapid reactions with chlorine in sunlight due to the presence of ultraviolet (UV) light. UV light provides the energy needed to break the relatively strong carbon-hydrogen (C-H) and carbon-carbon (C-C) bonds, initiating free radical substitution reactions. The chlorine radicals formed in this process readily substitute hydrogen atoms in the hydrocarbon, resulting in the formation of chlorinated products. This reaction is specific to the presence of sunlight and is a characteristic feature of alkanes reacting with halogens under these conditions.

  4. When chlorine substitutes hydrogen atoms in the higher homologues of alkanes (such as higher molecular weight alkanes), a mixture of products known as chlorinated derivatives or chlorinated alkanes is formed. These products result from free radical substitution reactions initiated by ultraviolet (UVRead more

    When chlorine substitutes hydrogen atoms in the higher homologues of alkanes (such as higher molecular weight alkanes), a mixture of products known as chlorinated derivatives or chlorinated alkanes is formed. These products result from free radical substitution reactions initiated by ultraviolet (UV) light. Multiple hydrogen atoms in the larger hydrocarbon molecule can be replaced by chlorine atoms, yielding a mixture of mono-, di-, tri-, and so on, chlorinated products. The specific chlorination pattern depends on factors like reaction conditions and the availability of hydrogen atoms in different positions within the hydrocarbon chain.
