atoms are not lost or gained in a chemical reaction
The absorption of water is not a chemical reaction.
This chemical reaction is called dehydration.
Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.

The absorption of water is not a chemical reaction.
The chemical reaction is called combustion, where the gasoline and air mixture reacts with the spark to release energy in the form of heat and light, producing carbon dioxide and water as byproducts.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
It is not a chemical reaction.
No weight is ever gained or lost in a chemical reaction.
The chemical reaction of water with sodium is a chemical change.
This chemical reaction is called dehydration.
Yes, it is a chemical reaction.
Matter is never lost or gained in a chemical reaction. A chemical reaction cannot destroy or create atoms, it merely rearranges how they are connected and arranged in new molecules. While the atoms rearrange, energy is released (such as through light, fire or heat), or absorbed, (such as when plants use sunlight to make sugar out of carbon and water). Some atoms may evaporate, making the resulting product seem lighter or smaller, such as when coal or wood burns, but the atoms themselves are not destroyed.
