2. Write the steps of agriculture in the correct order
3. What are metalloids? Name three metalloids.
4. Define Corrosion.​

Answer 1

Answer:

PLEASE MARK IT AS THE BRAINLIEST

Explanation:

1. Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. In electroplating, the deposited metal becomes part of the existing product with the plating/coating.
2. The main steps for agricultural practices include preparation of soil, sowing, adding manure and fertilizers, irrigation, harvesting and storage.
3. metalloids, an element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid non-metals or semiconductors.
4. Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.

Answer 2

Answer:

1. Electroplating is a process in which we put a coating of one metal on another to reduce the corrosion.

2. Ploughing

sowing

adding manure

irrigation

harvesting

storage

3. Metalloids are the elements who have the properties of both metal and non metal. eg. boron, silicon, germanium.

4. Corrosion is the natural process in which a refined metal become corrode and form oxides, hydroxide etc. due to the Acton AF air and moisture.
