Explanation

In Karst topography, both gypsum and dolomite are soluble.

They can form karst landscapes through dissolution.

This process is similar to limestone, though it occurs at varying rates.

Explanation

Real gases show deviation from ideal behavior at low temperature and high pressure.

Due to increased intermolecular forces and reduced volume available for gas molecules, which contradicts the assumptions of ideal gas behavior.

Explanation

Joseph Priestley discovered laughing gas (nitrous oxide) in 1772.

It was later studied for its anesthetic properties.

Explanation

• Chlorination is the process of adding disinfectants, such as chlorine, to water to kill harmful microorganisms.
• It prevent the spread of waterborne diseases.

Explanation

A concentrated solution has a large amount of solute compared to the solvent.

Therefore, the solute-to-solvent ratio is high in such a solution.

Explanation

An aqueous solution is one where the solute is dissolved in water.

"Aqua" means water, making it the key solvent in such solutions.

Explanation

Neon (Ne) is a noble gas.

It is exists as a monoatomic (single-atom) molecule under normal conditions.

Explanation

Magma that is low in silica and high in iron and magnesium is mafic magma.

Mafic magma is also known as basaltic magma

Silica content: Mafic magma has a silica content of roughly 50%. 

Mafic magma contains dark-colored minerals, such as olivine and pyroxene,

Explanation

In a bomb calorimeter, reactions are carried out at constant volume.

This is because the calorimeter is designed to keep the volume constant during the reaction.

Any heat released or absorbed during the reaction causes a temperature change, which is measured to determine the heat of the reaction.

The constant volume ensures that the heat measured is solely due to the chemical reaction taking place

Without any external influences like changes in pressure or volume.

Explanation

Rock candy is made by crystallizing sugar from a supersaturated solution using a seed crystal.

This process is known as the seedling technique, where crystals slowly grow over time.
