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.
Unused chemicals might be contaminated, and if you poured it back into the original container, you can ruin the entire contents.
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.

If you keep unused glue in an airtight container it will be saved.
Biohazard containers for needles are referred to as a "sharps container". Whether used or unused, any uncapped needle should be disposed of in the sharps container. A needle might be uncapped but unused-- for example, if the needle was bent or the tip flawed, or the medication was NOT given to the patient for any reason.
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.
about 90 percent.
After my opinion it is not recommended in laboratory.
$40.00
A original Beetles ticket is worth $2,000,000. That is a lot of money.
If unused chemicals are not poured back into their containers, they will be wasted. Also, they could be dangerous and should not be left lying around.
