Science Concepts Flashcards

Front

A compound held together by opposite electrical charges is an ionic compound.

Back

An ionic compound is formed when atoms transfer electrons.

Front

The attraction of one water molecule for another is known as cohesion.

Back

Cohesion is responsible for water's high surface tension.

Front

Carbon can form up to four bonds, which is a reason why it is important for life.

Back

This tetravalency allows carbon to form a variety of complex molecules.

Front

Nitrous oxide (N₂O) is not considered an organic compound because it contains no carbon.

Back

Organic compounds are primarily based on carbon.

Front

When a peptide bond forms between two amino acids, water is released.

Back

This process is known as a dehydration synthesis.

Front

A change in temperature indicates a change in the average speed of a substance’s particles.

Front

Entropy describes the disorder in a system like a messy room.

False

Front

The smallest part of a covalent compound is a formula unit.

Front

Brownian motion is motion caused by the collisions between particles.
