silver nitrate AgNO3 is used for silvering mirrors

acetone Type your answer here... acetone
Yes. One method used allows dissolving your compound in a mix of acetone and toluene for instance. as the acetone evaporates, the mix becomes less polar and the compound recrystallises.
Mirrors are used in the bathroom, in the hallway, in and on your motor vehicle, and up on the stage for magic acts. There are also parabolic mirrors that are used for looking at the stars by collecting and concentrating starlight.

Silvering
Its ethanol.. NOT acetone!!
There is a silvering in the vacuum flask in order to reduce the loss of heat through the means of radiation.

If only the silvering is gone, it can still be used, but it won't be as good. However, quite often the silvering is inside the vacuum compartment; if the silvering has vanished because the glass cracked, it is very probably unsafe to use. A thermal flask works by preventing heat conduction (the vacuum layer will not conduct heat) and by preventing heat radiation (the silver layer reflects the heat back at the contents). Without the silver layer, the heat will not be reflected. The flask will still work, but will lose or gain heat faster that it would if the silvering was intact. Note: The "silvering" on older flasks may be mercury. If the envelope is cracked and the mercury evaporates, it could prove toxic. Newer flasks use aluminum.
Acetone is usually added to cylinders of acetylene to stabilize it.

nail polish
my finger alreay add gum so i dont know what to do, and how to used acetone
It is because the silvering for the mirror is separating from the glass. Apparently this is a fairly common problem for heated mirrors. You need to replace the glass or whole housing.
