Okay so because of the difference in density a simple method for telling the difference between the two is to put a sample in a container with oil, because water has a higher density than the oil it would sink to the bottom but alcohol on the other hand is lighter than oil and would float on top of the oil.
However with this question I think that what you would do is use the ice to find out what the substance is, it would float on top of the liquid if it were water because the water is denser than ice but the ice would sink if it was alcohol because the alcohol is less dense than ice.
I hope this helps you, good luck : )
Based on Heisenberg's uncertainty principle, the position and velocity of a particle cannot be determined simultaneously with accuracy.
In other words, Heisenberg's uncertainty principle states that the more accurately we know the position of a particle the less accurately we can know its velocity. Mathematically it is given as:
Δx.mΔv >= h/2π
where: Δx = uncertainty in position
m = mass
Δv = uncertainty in velocity
h = plancks constant

In neutralization process or titration process, we use the formula;
(M1V1)H3PO4 = M2V2(Ca(OH)2)
M1 = 0.600 m
V1 = 10.0ml
M2 = unknown
V2 = 12.5ml
M1V1 = M2V2
0.6*10 = 12.5*M2
M2 = (0.6*10)/12.5 = 0.48m
Therefore, the answer is 0.480m
