Which of the following is a chemical change?

A Water vapor in the air turns to liquid water in the form of rain
B The oxygen in the air forms ozone in presence of UV rays
C Dust and soot particles being suspended in the air
D Sulphur dioxide being released in the air

Respuesta :

I think that it’s A i have done a test on this before so I think it’s A

the answer is B not A

let me explain why see a says water vapor in the air turns to liquid water in the form of rain see that is a physical change not a chemical change it is B because it is undergoing a chemical change by the uv rays for that reason it is not D because that is just releasing sulfur dioxide in the air that is not a chemical change nor a physical change so then i leaves us with C so C is wrong because it just being suspended in the air not physical or chemical change
