it takes (according to my 3,405 paged book on pollution)45.35466 seconds.
The chemical reac- tions that change air pollution to acid rain can take from several hours to several days.
Chemical reactions are sources of pollution. Some examples of these reactions are: combustion, burning of fossil fuels and acid rain.
A neutralization reaction is a chemical change.
These are not changes but substances.The reaction is a chemical change.
It will be an chemical reaction .
The chemical reac- tions that change air pollution to acid rain can take from several hours to several days.
This is a chemical reaction (dito change).
yes
Be careful with your terminology.Mixing aluminum and hydrochloric acid is not a chemical change.The resulting reaction, however, is a chemical change.
No, it is not a chemical change. For example, if you put gold bubbles into any single acid, no chemical change will take place.
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
yes its a chemical change you get table salt and water out of it
