Phytoremediation uses plants and related microbes to cleanse pollutants from soils and waters. Yudha Gusti Wibowo's research in a controlled environment explores phytoremediation's potential in treating mixed wastewater. Wibowo suggests that Pistia stratiotes, a floating aquatic plant, and Eichhornia crassipes, a water hyacinth, are capable of removing heavy metals like Fe (A) and Mn (B) from wastewater over time.11 Mark For ReviewWhich finding, if true, would directly support Wibowo’s claim?A) After exposing Pistia stratiotes to contaminated wastewater, X-ray fluorescence microscopy revealed an average concentration of 10ppm of Fe (A) within the plant tissues.B) After exposing Pistia stratiotes to contaminated wastewater for five weeks, Pistia stratiotes exhibited substantial growth.C) After exposing Pistia stratiotes to contaminated wastewater, the team observed no accumulation of the introduced Fe (A) and Mn (B) isotopes within the tissues of Pistia stratiotes.D) After exposing Pistia stratiotes to contaminated wastewater for five weeks, the concentration of microbes such as Pythium and Rhizoctonia has been found to exhibit a significant increase.

What method uses bacteria to help extract copper from low-grade copper ores?PhytominingReduction by carbonBioleachingElectrolysis2What type of plants does phytomining depend on? Plants that can absorb copper ions from soilPlants that can detoxify copper ionsPlants that can release copper ions into soilPlants that can make copper ions during photosynthesis3What two methods can be used to extract copper from a solution of copper sulfate produced by bioleaching or phytomining?Neutralisation or reduction by carbonNeutralisation or displacementElectrolysis or displacementElectrolysis or thermal decomposition4In the electrolysis of copper, which half equation shows what happens at the negative copper electrode? 2Cu2+(aq) + 2e– → 2Cu(s)2Cu(s) → 2Cu+(aq) + 2e–Cu(s) → Cu2+(aq) + 2e– Cu2+(aq) + 2e– → Cu(s)5What is the balanced symbol equation for the displacement reaction between copper sulfate and iron?Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)Fe(s) + CuSO4(aq) → FeS(aq) + CuO4(s)FeSO4(aq) + Cu(s) → Fe(s) + CuSO4(aq)Fe(s) + CuSO4(aq) → FeO4(aq) + CuS(s)6Which of the following is not an advantage of bioleaching and phytomining over the traditional methods of extracting copper from high-grade ores?Removes toxic copper from soilMore energy efficientDoes not require miningVery fast methods
