Explanation

The magnitude of a unit vector is always 1.

If this question refers to a general vector,

The magnitude is calculated based on its components,

But if it's asking conceptually or generally, then 1 is the correct choice.

Explanation

Galileo Galilei was a renowned astronomer, often called the "father of modern observational astronomy."

He made key improvements to the telescope and supported the heliocentric theory.

Explanation

 There are two isomers possible for the molecular formula C₂H₆O: ethanol (also known as ethyl alcohol) and dimethyl ether.

These two molecules have the same number of carbon, hydrogen, and oxygen atoms

However, their atoms are arranged differently, resulting in distinct properties

Explanation

The chemical formula CH₃COOH represents acetic acid, a weak organic acid commonly found in vinegar.

Key Information:

Common Name: Acetic acid (systematic name: ethanoic acid).

Properties:

• Weak acid (partially dissociates in water).
• Pungent smell, sour taste (vinegar contains ~4–8% acetic acid).

Explanation

Isotopes are atoms with different atomic masses that have the same atomic number.

The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Isotopes:

• The isotopes are a group of atoms that have the same atomic numbers but different mass numbers.
• That means all isotopes of an element have the same number of protons in their atomic nuclei and the same number of electrons in the electron cloud surrounding the nucleus.

Difference between isotopes

• Isotopes differ in the total number of neutrons present in their respective atomic nuclei.
• Thus they have different mass numbers.
• Different isotopes of the same element are having different masses.
• Protium (1 proton,1 electron, and no neutrons), Deuterium (1 proton, 1 electron, and 1 neutron), and Tritium (1 proton, 1 electron, and 2 neutrons) are examples of isotopes of Hydrogen.

Explanation

Avogadro's number represents the specific quantity of particles (atoms, molecules, ions, or electrons) contained in one mole of a substance.

It's a large constant value approximately equal to 6.022 x 10^23.
