They are made up of atoms of only one type of element.
They are made up of particles that are arranged in a repeating pattern.
They are made up of a random ratio of elements that are bonded together.
Ionic compounds are made up of particles that are arranged in a repeating pattern. Therefore, the correct option is option C.
A specific class of chemical compound known as an ionic compound is created when two or more atoms share electrons. It is made up of anions, which are negatively charged ions, and cations, which are positively charged ions. Most frequently, ionic compounds are created when a metal interacts with a non-metal. The non-metal atom receives one or more electrons to become an anion during this reaction, whereas the metal atom loses one or more electrons to become a cation. The development of a stable ionic compound happens as a result of the electrostatic forces that draw these oppositely charged ions to one another.

The wave with the longest wavelength is (A,B,C). The wave with the smallest amplitude is (A,B,C). The wave with the most energy is (A,B,C).
A is the wave with the longest wavelength. The graph clearly shows this since wave A has a larger wavelength than waves B and C. Wave A has the longest wavelength when compared to the other two waves.
C is the wave with the least amplitude. The graph shows this since wave C has a significantly lesser amplitude than waves A and B. Wave C has the least amplitude when compared to the other two waves. B is the most energetic wave.
The graph shows this because wave B has a larger amplitude than waves A and C. Wave B has the greatest amplitude when compared to the other two has the more energy in comparison to the two.
The longest wavelength wave has the lowest frequency and the lowest energy. A wave's wavelength is inversely related to its frequency, which implies that as the wavelength grows, so does the frequency. Because energy is proportional to frequency, the wave with the longest wavelength has the least energy.
The wave with the smallest amplitude has the least amount of energy. The largest displacement of a wave from its equilibrium position is referred to as its amplitude. The energy of a wave is exactly proportional to its amplitude, therefore as the amplitude falls, so does the energy.

Cl₃ is formed by thecombination of 3 chlorine atoms. Hence, not a single element and not a compound. Instead Cl₃ is a molecule of chlorine.
Molecules are the combination of atoms of same element or are the basic units of a compound. A compound is formed by the combination of two or more atoms of different elements.
The combination of atoms can be different bond types, such as ionic bond, covalent bond, hydrogen bonding etc. The type of bond is dependent on the nature of atoms.
Combination of same atoms in any number are forming the molecules of that element and not a compound. Hence, Cl₃ is a molecules and not element or compound.

Answer:
CI3 is a compound called carbon tetra iodide
b. The concentration of Cl⁻ ion will be 0.1M.
c. The concentration of undissociated H₂O molecules remains unchanged.
d. The pH of the beaker's contents will be neutral.
e. The pH of the beaker's contents falls.
Answer: Option (e) is the correct answer.
Explanation:
Since, the beaker contains NaOH solution whose pH is 13. As pH of NaOH is greater than 7 so, it means that this solution is basic in nature.
Whereas pH of HCl solution is equal to 1. As its pH is less that 7 so, it is acidic in nature.
Hence, when we add 10 ml of HCl into 100 mL of NaOH then there will be a slight decrease in pH of the solution because an acid is being added into the NaOH solution.
Thus, we can conclude that the statement pH of the beaker's contents falls, correctly describes the results of this mixing.

1. Nucleus: Contains genetic material, controls cell activities.
2. Mitochondria: Produces energy through cellular respiration.
3. Golgi apparatus: Modifies and packages proteins.
1. Nucleus: The nucleus controls the cell by storing DNA instructions. It affects cell growth, reproduction, and metabolism by regulating gene expression.
2. Mitochondria: Cellular respiration powers mitochondria. They convert foods into cell energy source ATP. Metabolism and cell signalling depend on mitochondria.
3. Golgi apparatus: It changes and packages endoplasmic reticulum proteins and lipids. Cisternae are stacked membranous sacs. The Golgi apparatus adds carbohydrates or lipids to proteins, organises them into vesicles, and guides them within or outside the cell. It is crucial for intracellular transport and secretion.
