Yes only some... It depends
Depends on the chemicals and reagents.
If you leave them open for a very long time or add other chemicals to it then yes they can sometimes go bad but most spa chemicals are good
This standard procedure -dry and clean spatula in scooping solid chemicals from reagent bottle- should prevent contamination of - and exposure to dirt and humidity to - the other chemical reagents.
It depends on what the chemicals are and the experiment itself. Also, it's not clear if you're asking about what the reagents are held in for storage prior to the experiment, what they are held in temporarily during the course of the experiment but before they are actually combined, or what they are held in when they are in the process of being combined.
It can do2 things, good and bad.
Grignard reagents are stable in ether medium. Ether generally forms an adduct with Grignard reagents. In addition, if solvents containing acidic hydrogens are present, Grignard reagents are decomposed to the corresponding hydrocarbon.
The chemicals which are involved in a reaction are called Reagents or Reactants
Reagents Reactants
Since a "reagent" is synonymous with "chemical", there are as many reagents as there are chemicals - pretty much a near-infinite list.

To contain foods (liquids, granulated, powdered), chemical reagents, other chemicals.
ROMIL is a producer of high purity chemicals, solvents, acids and reagents for both scientific and industrial applications.
The same things that make other electronics go bad: water, chemicals, and extreme temperatures.

The substance (or substances) initially involved in a chemical reaction are called reactants or reagents
