the identity of element remains same
cyanoacrylate
When cyanoacrylate polymerizes, the cyanoacrylate sticks together on an atomic level, and it becomes solid. Super Glue solidifies in all the microscopic crevices of an object that it moved into when it was a liquid, and it can form chemical bonds with any anions in the object.
Given what we know about lab safety, we can confirm that when dealing with unstable and erratic equipment such as the stirring mechanism, in this case, the best course of action is to deactivate the equipment until further notice.
<h3>Why should we turn off the equipment?</h3>
- The erratic nature of the stirring mechanism is making the entire system unstable.
- When dealing with a hot plate, and heating substances, we need to maintain stability at all times.
- We do this to avoid spills that may cause burns or other unwanted damages.
- Therefore, until we know why the stirring was erratic, we must turn the mechanism off.
Therefore, we can confirm that when dealing with faulty or unstable lab equipment, we must deactivate the equipment immediately in order to preserve our lab safety.
