Yes but they require specific temperatures to react.
Yes, it is true: all chemical reactions create new molecules of compounds.
The reaction depends on the solution, if there is a reaction at all.
All liquids are not the same: they have different physical and chemical properties.
The most common indicators of a chemical reaction are: 1. A color change. 2. A temperature change. 3. Bubbles (indicating a gas) 4. A precipitate (a solid that settles out of liquids) A chemical change can feature all, none, or any combination of these.
Any chemical has that capacity, if you create the necessary conditions of temperature and pressure. All elements and all compounds can exist as solids, liquids, or gases.
That depends entirely on the chemical reaction that you may be trying to create. Not all mixtures require salt.
Vapour is not a chemical reaction; instead, it is a tangible substance in a gaseous state and has no necessary association with chemical reaction at all.
Many liquids can be mixed forming true solutions.
false
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.
A catalyst undergoes no chemical change during a chemical reaction.
Mass is not a reaction at all; it is a physical property.
