Reteach and Remediate: Matter/Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement. It is greatest when the object is at its highest point.

Front

What elements generally make an ionic bond?

Back

An ionic bond is typically formed between a metal and a nonmetal.

Front

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

SiO2.

Front

What type of mixture is a density column?

Back

A density column is an example of a heterogeneous mixture.

Front

What is the energy transformation in a circuit with a glowing bulb?

Back

The energy transformation is chemical energy → electrical energy → light energy.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the composition is not uniform and different components can be seen.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.
