20 points will favor answer guys i could really use some on this question which of the following is a chemical change? water vapor in the air turns to liquid water in the form of rain the oxygen in the air forms ozone in presence of uv rays dust and soot particles being suspended in the air sulphur dioxide being released in the air you : )

Answer : Option B) The oxygen in the air forms ozone in presence of UV rays

Explanation : The other given options for the chemical change seems to be irrelevant as the option A which converts  water into different forms can be called as physical change, option C only dust and soot particle are released in air where no new substance is formed And in option D sulfur dioxide is getting released into air which is also a form of a physical process.

So in option B we can see a new compound getting formed which is ozone in presence of UV rays hence it is a chemical change.

You would do 1500/4 and the answer is 375
