Front

What occurs at the anode in an operating electrochemical cell?

Back

Loss of electrons.

Front

What term represents the strength of the attraction an atom has for the electrons in a chemical bond?

Back

Electronegativity.

Front

What happens to the pH of a solution when the concentration of hydrogen ions is decreased by a factor of ten?

Back

The pH increases by 1.

Front

Which bond is most polar: C–O, S–O, H–O, or N–O?

Back

C–O.

Front

How is the molecular polarity and charge distribution in carbon dioxide (CO₂) described?

Back

Nonpolar and symmetrical.

Front

Define electrochemical cell.

Back

A device that converts chemical energy into electrical energy through redox reactions.

Front

What is the definition of electronegativity?

Back

The tendency of an atom to attract electrons in a chemical bond.

Front

Explain the relationship between pH and hydrogen ion concentration.

Back

pH is the negative logarithm of the hydrogen ion concentration; a decrease in hydrogen ions increases pH.

Front

What is a polar bond?

Back

A bond between two atoms with different electronegativities, resulting in a distribution of charge.

Front

What is the significance of molecular symmetry in determining polarity?

Back

Symmetrical molecules are often nonpolar, while asymmetrical molecules are usually polar.
