The downdraft is significantly stronger than the updraft in either the dissipating stage (B) or the mature stage (C).
Hope this helped :)
Answer:
Aluminum
Explanation:
Because there's no other element that has this exact electron configuration
Explanation:
its answer is displacement reaction
Answer:
An ionic bond is that in which an electron is trasferred to another atom. Atoms that are considered metals have a low electronegativity meaning they are less likely to gain any electrons. Atoms that are non-metals have a higher electronegativity and are more likey to gain electrons than lose electrons. When an electron is either lost or gained by another electron the atome becomes more stable. Atoms with a complete and balanced valence shell stay close together because of the Nucleus with its strong electromagnetic pull. The stronger the pull the more likely the atom will gain an electron. The weaker the pull the more likely it will lose an electron.
When a non volatile solute is added to a solvent, the vapor pressure of the solvent will decrease.
Vapor pressure is a colligative property. Which means that it will be affected by the number of particles of solute.
The relationship between the concentration of the solute and the vapor pressure is given by Roult's Law
ΔP = Xsolute * P, where ΔP is vapor pressure lowering, Xsolute is the molar fractionof the solute, and P is the vapor pressure of the solvent.
Then lets find Xsolute
X solute = # moles solute / # moles solution
# moles solute = 75.0 grams / molar mass
molar mass of C12H22O11 = 12*12g/mol + 22*1g/mol + 11*16g/mol = 342 g/mol
# moles solute = 75.0/342 mol = 0.219 mol
# moles of solvent = grams of solvent / molar mass of solvent
# moles of solvent = 180 grams /18 g/mol = 10 mols
Xsolute = 0.219 mol solute / (10 + 0.219) mol solution =0.0215
ΔP = 0.0215*26.7 torr = 0.57 torr
Answer= 0.57 torr
