________ provide a path for electricity to flow.

• Conductors

• Insulators

Answer explanation

Conductors are materials like metals where electricity easily flows. Insulators are materials like rubber or plastic. Electricity does not flow through these materials.

A car battery is a _____ cell, which means it can be recharged.

• Primary

• Secondary

Answer explanation

The alternator helps to reverse the chemical reaction that happens in the battery. It restores the metals to their original form and charges the battery.

In a car battery the lead peroxide plate ________ electrons and is ________.

• gives up, oxidized

• accepts, oxidized

• gives up, reduced

• accepts, reduced

Answer explanation

The lead peroxide plate gives up electrons into the electrolyte. Anything that gives up electrons is the oxidizing agent in a redox reaction.

The lead plate ______ electrons and is ________.

• accepts, reduced

• gives up, reduced

• accepts, oxidized

• gives up, oxidized

Answer explanation

The lead plate accepts electrons from the electrolyte. Anything that accepts, or gains electrons in a redox reaction is the reducing agent. It is reduced because it becomes more negative as it gains electons.

True or False: All the electrons in the battery are balanced, which causes the movement of electrons.

• True

• False

Answer explanation

An imbalance of electrons is why the electrons will begin to flow.
