Unused chemicals might be contaminated, and if you poured it back into the original container, you can ruin the entire contents.
If the container used to take the chemical has some contamination, the entire stock bottle will be contaminated.

you shouldn't cause something bad can happen
the chemicals have been slightly changed and could react differently than expected
It may have become contaminated and would contaminated the chemical in the container. You should disposed of unused chemicals in the proper containers.
Simply, because contamination may occur
An unused portion of a chemical taken out of its container should be properly disposed of. The original container has identification information and warnings. Chemical that been poured out may become contaminated so should not be poured back.
Of course, for example, Potassium Manganate(VII), KMnO4 are usually kept in a black container, because it will oxidize easily when it expose to sunlight. Different chemical store in different kind of container depend on the chemical properties of the chemical. With many chemicals it is illegal to store the chemical unless it is in its original container and has the paperwork with the container.
where do I dispose unused periitoneal solution
O2 is the unused byproduct of photosynthesis, that you use during cellular respiration.
Because the process of producing the flame is a chemical reaction. The reaction can only exist if there are unused chemicals to fuel the change. Once all the chemicals are used up - the reaction stops.
Yes!
because it will contaminate the liguid/solution inside the bottle..tha's why you should always throw excess liquid solution. the contaminated chemical that is used could also cause a chemical reaction therefore having a high explosion risk.
no, sorry!
Get a baby bottle pop candy and look all over it then you will see the code there will be unused codes on every pop.
After my opinion it is not recommended in laboratory.
about 90 percent.

No, no charity will take unused prescription medication. Your best option is to return them to the pharmacy and they can dispose of them. You shouldn't flush them down the toilet/sink or throw them in the trash.
minimize soil depletion and encourage soil fauna
no, and no.
