cabon dioide and oxygen
No. Water vapor occurs naturally and is harmless, and is needed for precipitation. ********************* It could be argued both ways. Water vapour is considered a pollutant by people because of its apparent 90% contribution to the natural greenhouse effect. Though this may be the case, water vapour is, well, simply that: water vapour. It is what turns into rain, and rain is good. So both ways, rain could be considered a pollutant or not.
Chemical change
what is the answer uses both chemical and electrical stimuli
Both
This is a tough one - I can make a case for both. It could be considered a physical change because at the end of the mile you are the same individual, just one mile away. It could also be considered a chemical change since you are converting ATP to ADP and burning glucose into carbon dioxide and water during the run.
Ozone is beneficial in stratosphere. It acts as a pollutant at ground level.
Ozone occurring at 'our' level in the atmosphere is a pollutant, because it is harmful to people and some materials (such as rubber). However in the top of the atmosphere it acts as a 'shield' by stopping UV from the Sun, which would be harmful to human health.

Chapati is beneficial among the both of them. It is considered to be light while rice is considered to be heavy.rice has a lot of fiber whereas rice contains a lot of carbohydrates and fats.
Ozone is good at the stratospheric level. It is a pollutant at ground level.
The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
Gasoline
It is not. It is beneficial for the parents.
Gasoline
A good nights sleep is more beneficial than burning the candle at both ends.
it is harmful for them because as we know they are capable of holding life in them. both of them when they are "dead" stink!
Ozone is good at atmospheric level. It is bad at ground level as pollutant.
