What is the hybridization of the central iodine atom in i3−?
Ainat [17]
The central iodine atom in triiodide has sp3d hybridization.In triiodide anion, the central iodine atom has three equatorial lone pairs of electrons and the terminal iodines are bonded axially in a linear shape. Electrons in sp3d hybridization are arranged in trigonal bipyramidal symmetry.
Explanation:

When you draw the Lewis structure of this particle, you'll realize that the central I atom has a pair of bonds and three individual pairs of electrons. as a result of there are five things around that central I atom, it's<span> sp3d hybridized.
</span>
The bonds during a gas<span> (CH4) molecule </span>are fashioned<span> by four separate </span>however<span> equivalent orbitals; </span>one<span> 2s and </span>3<span> 2p orbitals of the carbon </span>interbreed<span> into four sp3 orbitals. </span>within the<span> ammonia molecule (NH3), 2s and 2p orbitals </span>produce<span> four sp3hybrid orbitals, </span>one among that<span> is occupied by a lone </span>try<span> of electrons.</span><span>

A solution is made
Anna11 [10]

Answer:

99.3%

Explanation:

The percent by mass of the solute can be expressed as:

  • % mass = \frac{MassSolute}{MassSolute+MassSolvent} * 100%

And for this problem:

  • Mass of Solute = Mass of sodium lithium chloride = 29 g
  • Mass of Solvent = Mass of Water

So to calculate the percent by mass first we need to <u>calculate the mass of water</u>, to do so we use its<em> density</em> (1 g/L):

  • 202 mL is equal to (202/1000) 0.202 L.

Density water = mass water / volume

  • 1 g/L = mass water / 0.202 L
  • Mass water = 0.202 g

Now we have all the data required to <u>calculate the % mass:</u>

  • % mass = \frac{29g}{29g+0.202g} * 100 % = 99.3%
