Flashcardizz- Quiz: Atoms, Chemical Bonding, and Properties of Water

Front

What is pH?

Back

pH is a scale used to measure the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What pH value represents a base?

Back

A pH value greater than 7 represents a base. For example, a pH of 8.1 indicates a basic solution.

Front

What type of bond forms between Sodium+ and Chlorine-?

Back

An ionic bond forms between Sodium+ and Chlorine-, where electrons are transferred from one atom to another.

Front

What is cohesion in terms of water molecules?

Back

Cohesion is the attraction between water molecules, which allows them to stick together, contributing to surface tension.

Front

Where are protons located in an atom?

Back

Protons are found in the nucleus of an atom.

Front

What are the three properties of water?

Back

The three properties of water are cohesion, adhesion, and high specific heat.

Front

What is adhesion in terms of water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to climb up surfaces.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is the significance of high specific heat in water?

Back

High specific heat means water can absorb a lot of heat without a significant change in temperature, which helps regulate climate.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a partial positive charge on one side and a partial negative charge on the other, while nonpolar molecules have no charge separation.
