Which energy conversion occurs in an operating voltaic cell? A) electrical energy to nuclear energy B) chemical energy to electrical energy C) chemical energy to nuclear energy D) electrical energy to chemical energy

Option (C) is the correct answer.

Explanation:

A property that changes chemical composition of a substance is known as chemical property.

For example, precipitation, reactivity, toxicity etc are chemical property.

A chemical property or reaction will always lead to the formation of a new product.

So, chemical properties such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form.

On the other hand, a property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

Thus, we can conclude that the statement chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form, best describes chemical properties of matter.
