I’m assuming this is a true and false question. The answer is true. Phosphorus has a larger atomic mass. Phosphorus is number 15 on the periodic table. Phosphorus is a non-metal.
If there is a multiple choice then the answer would be 0.029. I hope this helps you
Answer:
69.79 mmHg is the pressure for the solution
Explanation:
Formula for vapor pressure lowering:
Vapor pressure of pure solvent(P°) - Vapor pressure of solution (P') = P° . Xm
Xm → Molar fraction of solute (moles of solute / Total moles)
Total moles = Moles of solute + Moles of solvent
Let's determine the moles:
50.36 g . 1mol/342 g = 0.147 moles of sugar
88.69 g. 1mol/ 18g = 4.93 moles of water
Total moles = 0.147 + 4.93 = 5.077 moles
Xm = 0.147 / 5.077 = 0.0289
If we replace data given in the formula:
71.88 mHg - P' = 71.88 mmHg . 0.0289 . 0.0289
P' = - (71.88 mmHg . 0.0289 - 71.88 mmHg)
P' = 69.79 mmHg
None of the above I believe it is what can form a tornado??
Answer:
Explanation:
The melting of the chocolate pieces one by one showed that it was caused by heat flowing through the foil bridge. The transfer of heat happened between the foil bridge and the chocolate pieces because they were touching each other.
