Explanation

• Gram atomic mass (GAM) is the atomic mass of an element expressed in grams.
• It represents the mass of one mole of atoms of that element.

Explanation

The compound with the most acidic proton is Thiol. 

Thiols (R-SH):

These are more acidic than alcohols due to the larger size of sulfur compared to oxygen, resulting in a weaker S-H bond and a more stable conjugate base. 

Explanation

Friedrich Wöhler synthesized urea from ammonium cyanate in 1828, marking the birth of organic chemistry.

This experiment disproved the belief that organic compounds could only be made by living organisms.

Explanation

In the solid and liquid phase, AlCl₃ forms a bridged dimer structure: Al₂Cl₆, where two Al atoms are connected via chlorine bridges.

This happens because Al³⁺ seeks stability through coordinate bonding, leading to a bridge-type (dimeric) structure.

Explanation

Explanation

 The crystal structures with a coordination number of 12 are Face-Centered Cubic (FCC) and Hexagonal Close-Packed (HCP).

In these structures, each atom is surrounded by 12 other atoms. 

Explanation

Chlorine can be displaced by fluorine (F).

This is because fluorine is more reactive than chlorine.

As halogen reactivity decreases down the group in the periodic table.

Explanation

In a Daniell cell, the following is used as a cathode:

• Copper (Cu): The copper electrode is reduced and gains electrons to form copper atoms.
• The half-reaction is: Cu2+(aq) + 2e- → Cu(s)

Explanation

The molar mass of sodium chloride (NaCl) is 58.44 g/mol.

To find the mass of 2 moles of NaCl, you can multiply the molar mass by 2: 2 mol × 58.44 g/mol = 116.88 g

Rounded to the nearest gram, this is approximately 117 grams.

Explanation

 A solution that has a relatively less amount of solute in comparison to the solvent is called a dilute solution.
