Okay its like whipping sweetheart it goes cold to hot from liquid to a solid substance so you would need a constant heat
Most of the mass of an atom is in the Nucleus.
Answer: UV Rays can't travel through glass, making it impossible to get a suntan because your body won't be able to respond if there is no UV getting to it.
Explanation: Glass absorbs and deflects a lot of UV light because the wavelengths aren't small enough to pass through and as a result, your body can't undergo its natural response of producing melanin, because the proteins activated by the UV damage won't be enacted.
it should be 50/50 percent
so 50%
hopefully this is right !
Answer:
The vapor-pressure lowering of the solution is 2,39 mmHg
Explanation:
The Raoult's law says that the vapor pressure of a solvent in a solution is always lower than the vapor pressure of the pure solvent. The vapor pressure lowering is directly proportional to the mole fraction of the solute. In mathematical terms that means:
ΔP =
<em>(1)</em>
Where:
ΔP is the vapor-pressure lowering of the solution
is molar fraction of solute
And
is the capor pressure of the pure solvent (86,0 mmHg)
The moles of naphthalene are:
<em>9,36x10⁻³ moles solute</em>
And the moles of benzene are:
0,328 moles solvent
Molar fraction of solute is:
<em>0,0278</em>
Replacing in (1)
<em>ΔP = 2,39 mm Hg</em>
I hope it helps!
