The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Bioremediation**: Bioremediation is a process that uses living organisms, primarily microbes, to remove or neutralize contaminants from soil and water. In this case, it specifically refers to the conversion of heavy metal pollutants into less toxic forms. 2. **Identifying the Role of Microbes**: Certain microbes have the ability to degrade heavy metals and convert them into less harmful substances. This is crucial for restoring the health of contaminated environments. 3. **Considering Different Microbes**: The question mentions several microbes, including E. coli, Rhizobium, Trichoderma, and Pseudomonas. Each of these has different roles in the ecosystem: - **E. coli**: Known for its ability to degrade various pollutants, including heavy metals. - **Rhizobium**: Primarily involved in nitrogen fixation in leguminous plants. - **Trichoderma**: A fungus that is beneficial for plant health but not specifically known for heavy metal degradation. - **Pseudomonas**: While it has various roles, it is not primarily recognized for heavy metal bioremediation. 4. **Selecting the Correct Microbe**: Based on the information provided, E. coli stands out as the microbe that specifically converts heavy metal pollutants into less toxic salts. Therefore, it is the correct answer for the question. 5. **Final Answer**: The microbe employed in bioremediation for the conversion of heavy metal pollutants in soil into less toxic salts is **E. coli**. ---

When a transition metal ion (usually) is involved in octahedral complex formation, the five degenerate d-orbitals split into two set of degenerate orbitals (3+2) . Three degenerate orbitals of lower energy (d_(xy),d_(yz),d_(zx)) and a set of degenerate orbitals of higher energy (d_(x^(2)-y^(2)" and "d_(z^(2)) . The orbitals with lower energy are called t_(2g) orbitals and those with higher energy are called e_(g) orbitals. In octahedral complexes, positive metal ion may be considered to be present at the centre and negative ligands at the corner of a regular octahedron. As lobes of d_(x^(2)-y^(2)" and "d_(z^(2) lie along the axis, i.e., along the ligands, the repulsions are more and so, high is the energy. The lobes of the remaining three d-orbitals lie between the Axis i.e., between the ligands. The repulsions between them are less, so lesser the energy. In the octahedral complexes, if metal ion has electrons more than 3, then for pairing them, the options are (i) Pairing may start with 4th electron in t_(2g) orbitals. (ii) Pairing may start normally with 6th electron when t_(2g)" and "e_(g) orbitals are singly filled. In which of the following configurations, hybridisation and magnetic moment of octahedral complexes are independent of nature of ligands. (P) d^(3) configuration of any metal cation (Q) d^(6) configuration of IIIrd transition series metal cation (R ) d^(8) configuration of Ist transition series metal cation (S) d^(7) configuration of any metal cation Select the correct code:

Air sample from an industrial town, heavily polluted by CO_(2) was collected and analyzed . In one anaylsis , 56L of air measured at 1 atm and 273 K was passed through a 250 mL of 0.025 M NaOH solution , where CO_(2)(g) was absorbed completely . 25 mL of the above solution was then treated with excess of BaCl_(2) solution where all the carbonate was precipitated as BaCo_(3)(s) . The solution was filtered off and the filtrate required 25 mL of a 0.005 MHCl solution for neutralization. ppm strenght of CO_(2)(g) , volume by volume i.e. , mL of CO_(2) per 10^(6) mL of air was :
