The process in which bacteria in the roots of plants convert nitrogen from the air into nitrogen compounds is a chemical change.

The absorption of nitrogen compounds through the roots of plants is a physical change.
Answered by GPT 3.5
The death and decay of animals and plants, which returns nitrogen compounds to the soil, is a chemical change. During decomposition, organic matter is chemically broken down into simpler compounds, including nitrogen compounds, through the action of bacteria and other decomposers.
Answered by GPT 3.5
The reaction of nitrogen and oxygen to form nitrogen dioxide during lightning storms is a chemical change. The high energy and heat from the lightning cause the nitrogen and oxygen molecules to chemically react, resulting in the formation of nitrogen dioxide.
Answered by GPT 3.5
The dissolution of nitrogen dioxide in rain is a physical change. When nitrogen dioxide comes into contact with rainwater, it dissolves and becomes dispersed throughout the water. No new compounds are formed; it is simply a physical mixing of the nitrogen dioxide with water molecules.
