If you quickly plunge a room-temperature mercury thermometer into very hot water, what will happen to the mercury level?\
jeka57 [31]

The answer is; The mercury level first falls then begin to rise rapidly.

This is because even though glass is not a good thermal conductor, the great heat variation causes the glass to gather heat and expand first even before the mercury is reached by the heat. This increases the volume of the lumen of the glass hence causing the mercury level to drop as the volume of the glass increases.

however, as the heat reaches the mercury, it also begins to expand and the levels stop falling and begin to rise.

A fan pulls in air from the surrounding area, which typically has high moisture levels.

When the air passed through the dehumidifier , it touches the cooling coils , which in turn pull moisture from the air by lowering temperature.

The Ksp of yttrium iodate, Y(IO3)3 , is 1.12×10−10 . Calculate the molar solubility, s , of this compound.
torisob [31]

Answer:

1.427x10^-3mol per L

Explanation:

Y(IO_{3} )_{3} ---- Y^{3+} +IO_{3} ^{3-}

I could use ⇌ in the math editor so I used ----

from the question each mole of Y(IO3)3 is dissolved  and this is giving us a mole of Y3+ and a mole of IO3^3-

Ksp = [Y^3+][IO3-]^3

So that,

1.12x10^-10 = [S][3S]^3

such that

1.12x10^-10 = 27S^4

the value of s is 0.001427mol per L

= 1.427x10^-3mol per L

so in conclusion

the molar solubility is therefore 1.427x10^-3mol per L
