Any excess materials that are not used during a laboratory experiment may be poured down the drain?
No. Chemicals should be disposed of in a safe manner. Usually directions for disposal can be found on the box/tube/packet that the chemical came in. If none can be found, ask a professional (teacher, lab assistant, poison control expert) what is the proper disposal for a certain chemical. Excess materials poured down the drain may be poisonous to the environment or people, and can leak from the sewage system to our ground water and eventually to our food.
What else can I help you with?
What is the use of Koplin jar in the laboratory?
to hold slides for staining or in between stains to rinse excess away with water
What are the safety precautions to be followed in the laboratory?
The safety precautions of a laboratory is entirely dependent on the subject what is it for. Whatever the laboratory is, there are several guidelines.Wearing the protective glasses all the time.Leave all your belongings away from your working bench.Do not eat or drink in the laboratory.Do not smell any chemicals or substances unless instructed.Do not light the Bunsen burner with a piece of paper.If anything is spilled, clean it immediately.Immediately report all the hazardous conditions to the instructor/invigilator or to the teacher.Be considerate of others (if anyone do an experiment nearby)Minimize the waste (including chemicals, filter paper etc.)Avoid reagent contamination.Leave all the reagents where they belong.Never put solid waste into sinks.Separate glass from solid waste.Return the excess re-usable material to the storeroom.
Does decay happen faster in dry or humid weather?
Decay happens at a faster rate in humid weather. Humidity is caused by excess moisture in the air. Water is notorious for decomposing organic materials faster.
What is a greater amount than what is needed?
Excess.
What is excess weight?
That is too much weight.
Can any excess materials that are not used during a laboratory experiment may be poured down the drain?
Most of the substances used in most laboratory experiments can be safely poured down a drain. However, laboratory experiments sometimes involve corrosive substances which would damage the plumbing if poured down the drain; they can also involve chemicals which, if they were to be mixed together as they are poured into the same drain, would undergo chemical reactions that might cause an explosion or a fire. And it is also possible that you are conducting experiments on highly toxic materials that would become an environmental hazard if poured down the drain. So not everything goes down the drain. You have to understand the nature of the substances that you are dealing with. Some thing go to a hazardous waste center instead, or can be neutralized in your own laboratory before you dispose of them.
What substances are removed from blood during dialysis?
waste materials that have toremoved by kidneys.

What materials removed from the kidney?
Materials removed from the kidneys are urea and water sugar!
How would you dispose of excess amalgam?
Mercury residues are collected for recycling by an authorized laboratory.
What wastes materials comprise the sweat or perspiration?
the waste materials are deadcells,excess salts and water
What waste materials comprise sweat or perspiration?

How thales experiment produce static elictricity?
Thales' experiment involved rubbing amber with fur, creating friction and transferring electrons between the two materials. This transfer of electrons led to an accumulation of excess negative charge on the amber, resulting in static electricity.
What is the use of Koplin jar in the laboratory?
to hold slides for staining or in between stains to rinse excess away with water
What materials are removed from the bloods through dialysis?
urea and excess salts
Why would you use sodium hydrocarbon and potassium hydroxide in a photosynthesis experiment?
In a photosynthesis experiment, sodium bicarbonate is used to provide a carbon source for the plant during photosynthesis. Potassium hydroxide is used to remove any excess carbon dioxide present in the experimental setup to simulate ideal photosynthetic conditions.
What was done in the experiment to ensurethat all KHCO3 was react?
In the experiment, excess HCl was added to ensure that all KHCO3 was reacted. Excess reactants ensure that all of the limiting reactant is completely consumed in the reaction, leaving none unreacted. When all KHCO3 reacts, the reaction reaches completion.
