Explanation

• In a saturated solution, the solvent has dissolved the maximum amount of solute possible under the given conditions.
• It leading to equilibrium between the dissolved and undissolved solute.

Explanation

• Lemon juice, which is primarily liquid, dissolves in water, another liquid, creating a liquid-liquid solution.
• Where both solute (lemon juice) and solvent (water) are in liquid form.

Explanation

The particles in a gas have the following characteristics:

• They move randomly, with no fixed pattern or direction
• They have unlimited space to move, as there are no boundaries or restrictions
• They move freely in any direction, without any obstacles or barriers
• They can travel long distances, as there are no constraints on their movement

Explanation

Increasing the proportion of reactants which have enough energy to overcome the activation energy: At a higher temperatures, more reactants have enough energy to overcome the activation energy. This increases the frequency of successful collisions so the rate increases.

Explanation

• Strontium has the largest metallic radius with a value of 215 pm (picometers).
• This is due to its position in the periodic table, as it is a heavy alkaline earth metal with a large atomic radius.

Here are the atomic radii of the elements you've listed:

• Strontium (Sr): 215 pm
• Calcium (Ca): 197 pm
• Magnesium (Mg): 160 pm
• Beryllium (Be): 125 pm

Explanation

Dipole-induced dipole force is the weakest among intermolecular forces, caused when a polar molecule induces a dipole in a nonpolar molecule.

It is weaker than dipole-dipole and ion-dipole interactions.

Explanation

In sp² hybridization, the unhybridized p orbital remains perpendicular to the plane formed by the sp² hybridized orbitals, contributing to the formation of a π bond.

Explanation

• When fuel is burned, carbon dioxide gas (CO₂) is primarily produced.
• The combustion of fuel, particularly hydrocarbons, typically results in the formation of carbon dioxide and water vapor (H₂O).

Explanation

• A concentrated solution has a high amount of solute relative to the solvent.
• Indicating that there is a large quantity of the dissolved substance compared to the amount of solvent.

Explanation

• The solvent is the substance that dissolves the solute, typically present in a larger amount than the solute.
• It can be a solid, liquid, or gas, and its molecules or atoms separate the solute molecules or atoms, allowing them to dissolve.
• Examples: water, alcohol, and acetone.
