The correct Answer is:
To solve the question about which microbe is employed in bioremediation for converting heavy metal pollutants in soil into less toxic salts, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Bioremediation**: - Bioremediation is a technique that uses microbes or bacteria to remove contaminants and toxins from the environment, including soil and water. 2. **Evaluate the Options**: - The options given are: - **Rhizobium**: A nitrogen-fixing bacterium that helps in enriching soil but is not primarily used for bioremediation of heavy metals. - **E. coli**: A bacterium that has some applications in bioremediation, but it is not specifically known for heavy metal detoxification. - **Trichoderma**: A fungus used mainly for controlling plant diseases and not specifically for heavy metal bioremediation. - **Pseudomonas**: A genus of bacteria known for its ability to degrade various pollutants, including heavy metals and polycyclic aromatic hydrocarbons. 3. **Identify the Correct Microbe**: - Among the options, **Pseudomonas** is recognized for its capability to degrade toxic compounds and is widely used in bioremediation processes, particularly for heavy metal pollution. 4. **Conclusion**: - Therefore, the correct answer to the question is **Pseudomonas** as it is specifically employed in bioremediation to convert heavy metal pollutants into less toxic forms. ### Final Answer: The microbe employed in bioremediation for the conversion of heavy metal pollutants in soil into less toxic salts is **Pseudomonas**. ---

    Alkali metal salts ionic and soluble in water. The solubility of an ionic compound depends on (i) lattic ethalpy and (ii) hydration enthalpy. These two factor oppose each other. If hydration ethalpy is high, the ions will have greater tendency to be hydrated and therefore the solubility will be high. The smaller the cation, the greater is the degree of hydration. The reducing behaviour of alkali metals in solution is also dependent on the hydration enthalpy besides other factors. The ionic mobility of Li^(o+) is less than of the Na^(o+) ion in solution because

    Explain the following observations giving an appropriate reason for each. (i) The enthalpies of atomization of transmition elements are quite high. (ii) There occurs much more frequent matal-matal bonding in compounds of heavy transition metals (i.e, 3^(rd) series). (iii) Mn^(2+) is much more resistant then Fe^(2+) toawards oxidation.

    Hydrogen accounts for approximately 75% of the mass of the universe. Hydrogen serves as the nuclear fuel of our Sun and other stars, and these are mainly composed of hydrogen. On the earth, though hydrogen is rarely found in the uncombined state. Since the earth's gravity is too weak to hold such light molecules, nearly all the H_2 originally present in the earth's atmosphere has been lost to space. In the earth's crust and oceans, hydrogen is found in water, petroleum, proteins, carbohydrates and other compounds and it is the ninth most abundant element on a mass basis. Hydrogen has three isotopes : hydrogen or protium () , deuterium or heavy hydrogen (D or ), tritium (T or ) . The physical properties of the three isotopes are different due to the difference in their masses, i.e. isotope effect. The chemical properties of the three isotopes are similar as they have the same electronic configuration. Reaction between hydrogen and oxygen is highly exothermic, and gas mixtures that contain as little as 4% by volume hydrogen in oxygen (or in air) are highly flammable and potentially explosive. 2H_(2(g))+O_(2(g)), DeltaH^(ɵ)=-485 kJmol^(-1) As hydrogen is environmentally clean it is an enormously attractive fuel. 'Hydrogen economy' is an emerging field in which it is thought that our energy needs can be met by gaseous, liquid and solid hydrogen. As hydrogen is no a naturally occuring substance such as coal, oil or natural gas, energy must be exploaded to produce hydrogen before it can be used. Which of the following fuel produces least environmental pollution?
