Predict the shape and hybridization of platinum tetrachloride (PfCl4)​

Chemistry
1 answer:
guapka [62]3 years ago
3 0

Answer:

Shape- square planar , hybridisation-sp3

Explanation:

Shape:

  1. VSPER theorey is used to determine both electron geometry and molecular geometry of a molecule.(PtCl4)2 molecular geometry is square planar
  2. Hybridisation:It undergoes sp3 hybridisation.since there are 2 unpaired electrons in this case, it is paramagnetic in nature

Select the substance that is thought to be partially responsible for depleting the concentration of ozone in the stratosphere. s
gogolik [260]

Answer:

cfcl3

Explanation:

When the cfcl3 in the atmosphere is hit by UV rays from the sun, it decomposes to Cl atoms. These Cl atoms then react with the ozone producing O2 and ClO. The ClO bombard with O atoms splitting the ClO up and the free Cl atom again bonds to another O3 molecule hence reducing it. One ClO can reduce several O3 molecules (up to 100,000) creating an ozone hole.

2Cl + O3 → 2ClO + 2O2

2ClO + 2O → 2Cl + 2O2

Determine the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution?
UkoKoshka [18]

Taking into account the definition of molarity,  the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 \frac{moles}{liters}.

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity=\frac{number of moles}{volume}

Molarity is expressed in units \frac{moles}{liters}.

<h3>This case</h3>

In this case, you have:

  • number of moles= 30 moles
  • volume= 0.80 L

Replacing in the definition of molarity:

Molarity=\frac{30 moles }{0.80 L}

Solving:

<u><em>Molarity= 37.5 </em></u>\frac{moles}{liters}<em />

Finally, the molarity of a solution that contains 30 moles naoh in 0.80 liters of solution is 37.5 \frac{moles}{liters}.
