Which is an example of a voltaic cell? a. a battery b. electrolysis of water c. electroplating of chrome d. a rechargeable battery

A. a battery is an example of a voltaic cell

Choice A is the correct option in this question.

Explanation:

When the Silver Nitrate and copper are put in a container then redox reactions takes place which is the reason behind production of charge in a voltaic cell.

In case of battery also the same reaction takes place but it in a greater magnitude Hence a battery can be said to be a combination of several voltaic cells or we can also say that a battery is a bigger voltaic cell that produces current in a much larger magnitude than a simple cell.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
