Here are the answers to the objective questions:

1. Which word is derived from word "Kheem".

   • The word "Chemistry" is derived from "alchemy," which has roots in the Arabic word "al-kīmiyā," itself possibly from the Greek "khēmeia" or "khemia," related to Egypt (Kemet). "Kheem" is a phonetic representation that aligns with the origin of chemistry.
   • Answer: c) Chemistry

2. What is symbol of silver.

   • The chemical symbol for silver is Ag, derived from its Latin name, Argentum.
   • Answer: a) Ag

3. Vertical columns present in modern periodic table are called.

   • In the modern periodic table, vertical columns are known as groups, and horizontal rows are called periods.
   • Answer: b) Group

4. Type of matter having fix shape and fix volume is called:

   • A solid is a state of matter characterized by a fixed shape and a fixed volume.
   • Answer: a) Solid

5. 1 PPM is equal to how many mill liters.

   • PPM (parts per million) is a unit of concentration, not a direct measure of volume. It represents 1 part of a substance per 1,000,000 parts of the total. If the question implies "what volume represents 1 part when the total is expressed in millions of milliliters," then 1 part would be 1 milliliter. This interpretation is necessary to match the given options, as a direct conversion of PPM to mL is not standard.
   • Answer: a) 1

6. PH of basic solution is.

   • A basic (or alkaline) solution has a pH value greater than 7.
   • Answer: d) 8 to 14

7. Fusion means.

   • Fusion generally refers to the process of joining or combining. In physics, nuclear fusion involves combining atomic nuclei. In chemistry, it can refer to melting (solid to liquid). "To Add" is the closest option representing combining or joining.
   • Answer: b) To Add

8. The corrosion of iron is called.

   • The specific term for the corrosion of iron, which involves the formation of iron oxides, is rusting.
   • Answer: a) Rust

9. Oxidation takes place at which electrode.

   • In an electrochemical cell, oxidation (loss of electrons) always occurs at the anode.
   • Answer: d) Anode

10. ---------- is a ----------

    • This question is incomplete as the first part of the statement is missing, making it impossible to determine the correct answer from the given options (Conductor, Non-Conductor, Semi-Conductor, Super-Conductor).
