During the distillation of solvents, generally drying agents such as calcium hydride, sodium, etc are used. If there is no solvent, these drying agents can catch fire at high temperatures, leading to explosion in most cases.
NO, you should never use anything but distilled water.
yes! Distilled water is what you should use. Never use tap water.
Look in the face of the problem and you will find the solution. Never run away from it
You should never add full strength coolant to any vehicle. Always dilute it with distilled water
I have been around many pregnant women & this will never happen if you keep hydrated.
As long as the solution is a water-based solution, it should be fine. You should never ever use a Bunsen burner to heat a flammable liquid such as alcohol, ether, acetone, etc.
Yes, as long as it has never been contaminated.
It is a cautionary story. It does not have a solution it is for instruction.
Proprietary Coolant available only from VW repair shops. Never, never use any other type of coolant as it will turn the radiator fluid into jelly and not work. In an emergency, you can add Distilled Water to get to the repair shop. Never, never, never use tap water under any circumstances.
Does a multi-step equation sometimes, always, or never have a solution?
Zero; they never intersect and therefore they do not have a solution.
Well the point of a solution is that any solids involved are dissolved. Otherwise there is never any chance of having a homogenous solution (equal concentration, anywhere in the volumetric flask)
