After some pretty extensive searching I found 25800 mg/kg-1 for a rat, that's what I used for my lab write-up so I hope it's right.
I believe that it is roughly 5.5g/l in humans.
the main reason why ethanol burns differently then ethanol and water mix is mainly because when you add the water to the ethanol you are making the ethanol less potent so it will burn weaker.
ethanol is a solvent
No, ethanol is an organic basic liquid, wine and beer contain ethanol, and it is flammable
So as not to 'waste' too much ethanol. To use 95 % ethanol allows some ethanol to be saved!
That question is too vague. I'm assuming you mean a little frozen ethanol into a larger volume of liquid ethanol. This being the case, the ethanol will melt. That's it.

LD50 measures the lethal dose of a substance that causes death in 50% of the test subjects, typically expressed in milligrams of substance per kilogram of body weight. It provides a standardized way to compare the toxicity of different substances.
The radiation LD50 of most insects is far higher than the LD50 of mammals.
that's not true, in fact magnesium sulfate has been tested on rats and dogs, and it does have an ld50. "The LD50 values were 206 mg/kg for males and 174 mg/kg for females"
1mg/kg

A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
True. The chemical with an LD50 of 1000mg/kg is less toxic than the one with an LD50 of 100mg/kg. LD50 is the lethal dose at which 50% of the test subjects die, so the higher the LD50 value, the less toxic the chemical is considered.
by definition ld50 is when 50% survive or dead,,answer will be 5 if i count well
The LD50 of phenobarbital in humans is estimated to be around 15 mg/kg when taken orally. LD50 represents the dose at which 50% of the test population would die as a result of the substance.
