Answer:
44.2 mmHg
Explanation:
We have to apply the colligative property of lowering vapor pressure:
P° - P' = P° . Xm
where P' refers to vapor pressure of solution
P° refers to vapor pressure of pure solvent
Xm is the mole fraction of solute
Let's determine the mole fraction (moles of solute / Total moles)
Total moles = Moles of solute + Moles of solvent
Moles of solute → 15 g . 1 mol/18g = 0.833 moles
Moles of solvent → 100 g . 1mol / 46 g = 2.174 moles
Total moles = 0.833 + 2.174 = 3.007
Xm = 0.833 / 3.007 = 0.277
We replace data in the formula: 61.2 mmHg - P' = 61.2 mmHg . 0.277
P' = - (61.2 mmHg . 0.277 - 61.2 mmHg) → 44.2 mmHg
Answer:
Electrons in a metal that aren't bonded with only one atom
Answer:
b. The pressure in the container will be 100mm Hg.
d. Some of vapor initially present will condense.
Explanation:
The vapor pressure of liquid Pantene rises when there is container where evacuation of water molecules is restricted. The pressure inside the container rises to 100 mm Hg and then liquid molecules start condensing. These molecule form vapors.
Answer:
The molecular shape and ideal bond angle of the 
is trigonalbipyramidal and 
respectively.
Explanation:
The structure of is as follows.(in attachment)
From the structure,
Phosphor atom has one lone pair and three hydrogens are bonded by six electrons.
Therefore, total electrons invovled in the formation is eight.
Hence, four electron groups which indicate the tetrahedral shape. But one pair is lone pair i.e, present on the phosphor atom.
Therefore, ideal geometry of the molecule is <u>Trigonalbipyramidal.</u>
The ideal angle of trigonalbipyrmidal is .
All three bonds of P-H has .
Therefore, ideal bond angle is <u>.</u>
Answer:
1. Diazonium salt
2. Coupling component
Explanation:
Azo dyes re synthesized by the combination of two organic compounds viz
1. Diazonium salt
2. Coupling component
1) For methyl red, the diazonium salt which is an intermediate product is produced by the reaction of hydrochloric acid (HCL) with anthranilic acid and sodium nitrate (NaNO₂)
2) The produced diazonium salt is then combined with dimethylaniline which is a coupling component rich in electrons to undergo a chemical reaction that by an aromatic substitution mechanism to produce methyl red as the final product.
