Question

Phytomining uses plants to extract nickel from low-grade ores. The plant contains 0.792 _________.

1) nickel
2) copper
3) iron
4) gold

Answer 1

The plant mentioned in the question uses phytomining to extract 0.792 of a metal, which is identified as nickel (Ni), based on the context of phytomining and the information provided.

Step-by-step explanation:

Phytomining, also known as agromining, is a technique that uses plants to extract metals from soil, particularly from low-grade ores. The plants absorb metal ions through their roots and concentrate these ions in their tissue. Once the plants have grown and absorbed the metals, they can be harvested, dried, and incinerated to recover the metals. In the case of this question, the plants contain 0.792 of a certain metal and you are asked to identify which one.

Considering the information provided and the context of phytomining, the metal that plants are typically used to extract, and which matches the abbreviation provided "0.792 _________" is nickel. The symbol for nickel on the periodic table is Ni, which corresponds to option 1) nickel. Therefore, when discussing phytomining in this scenario, the plant would contain 0.792 nickel.
