Explanation

The flame test is a qualitative analysis technique used to identify certain elements based on the color they produce when heated in a flame.

In the case of copper halides (such as copper chloride or copper bromide), the flame test produces a bluish-green color, which indicates the presence of copper.

Explanation

Organic qualitative analysis deals with the identification of functional groups in organic compounds.

Functional groups are specific groups of atoms within a molecule that determine its chemical properties and reactivity.

Explanation

The Analytical Chemistry deals with instruments and methods to separate, identify, and quantify the matter.

Explanation

According to the Arrhenius definition, an acid is a substance that increases the H+ ion concentration in aqueous solution.

HCl, HNO3, and H2SO4 all dissociate in water to produce H+ ions, making them Arrhenius acids.

CO2 does not dissociate in water to produce H+ ions.

Explanation

• One atmospheric pressure, also known as standard atmospheric pressure.
• It is defined as 101325 Pascals (Pa).
• This is the pressure exerted by the weight of the atmosphere at sea level.
• It is used as a standard unit of pressure.

Explanation

• The diagram that shows atoms are bonded with the same electronegativity is: A -----:----- B.
• In this representation, the bond is shown with a symmetrical distribution of electrons.
• It suggesting that the atoms have the same or very similar electronegativity.

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.
