A plant uses carbon dioxide and water to form food and oxygen. Why is this a chemical change?

because when the plant inhales c02 it exhales oxgen

Explanation:

The properties of carbon dioxide and oxygen are different.

Explanation:

A chemical change is defined as something that changes the substance of something (such as the creation of water from hydrogen and water), and can be figured out if chemical or physical based on different changes and properties. Your answer will be  The properties of carbon dioxide and oxygen are different because these are two different elements (compounds in case of CO2) that combine to form a different substance, thus changing the identity of the substance.

Photosynthesis is a chemical reaction that occurs in plants by using radiant energy from sunlight. In this chemical reaction, carbon dioxide from the atmosphere and water from the soil are combined to produce sugar (glucose) that contains stored chemical energy.

the average speed is 24.57 km/hr
