Explanation

Mayonnaise is primarily made by emulsifying oil (usually vegetable oil) in water (along with vinegar or lemon juice and egg yolk, which contains emulsifiers).

This creates a stable mixture of oil droplets dispersed in the water phase.

Explanation

• Liquids have a lower mobility than gases.
• In a liquid, the molecules are close together and have a certain degree of attraction, which limits their ability to move freely.
• In contrast, gas molecules are widely spaced.
• It have little attraction, allowing them to move more freely and rapidly.

Explanation

Polymers that soften on heating and harden when cooled are called thermoplastics.

Explanation

• An Addition Reaction is also known as both a Combination Reaction and a Synthesis Reaction.
• All three terms refer to a chemical reaction where two or more substances combine to form a new, single compound.

Explanation

The angle through which plane-polarized light is rotated by a reacting mixture is measured by the optical rotation method.

Optical rotation, also known as optical activity, is a property exhibited by certain substances

That causes them to rotate the plane of polarized light passing through them

This rotation is quantified by measuring the angle of rotation, typically using a polarimeter

Explanation

The concentration of A after 29 seconds is approximately 0.15 M.

Explanation

Benzene is more volatile because it has a low boiling point and evaporates quickly at room temperature.

Volatility refers to a liquid's tendency to vaporize — benzene does so more readily than the others listed.

Explanation

• The incorrect statement is: Particles are in loose clusters.
• In solids, particles are actually closely packed and arranged in a regular pattern, with minimal space between them.
• This is what gives solids their rigidity and structure.

Explanation

• Sodium carbonate is produced by the Solvay process, also known as the ammonia-soda process.
• This process was developed by Ernest Solvay in the 1860s.
• It uses salt and limestone as the main ingredients, which are readily available and inexpensive.
• The Solvay process produces roughly three-quarters of the world's supply of sodium carbonate, with the remaining being mined from natural deposits.

Explanation

The standard hydrogen electrode (SHE) is used as a reference electrode with an assigned electrode potential of 0 V.
