Draw and Identify the different molecular shapes of the following-NH3-NO-CO2CH4CCl4
1. Draw and Identify the different molecular shapes of the following-NH3-NO-CO2CH4CCl4
Answer 5 points NH3 NO CO2 CH4 CCI4
2. Determine the molecular mass of a 1.42 grams organic compound in 50 grams CCl4
The molecular mass of organic compound : 183.23 g/mol
Further explanationSolution properties are the properties of a solution that don't depend on the type of solute but only on the concentration of the solute.
The term is used in the Solution properties
1. molalthat is, the number of moles of solute in 1 kg of solvent
2. Boiling point
Solutions from non-volatile substances have a higher boiling point and lower freezing points than the solvent
ΔTb = Tb solution - Tb solvent
ΔTb = boiling point elevation
ΔTb = Kb. mKb = molal boiling point increase
m = molal solution
We complete the data:
The boiling point constant for CCl₄: 5.03 ° C /m
boiling point: 76.72 ° C
Assuming an increase in the boiling point of the solution is: 77.5 ° C, then
ΔTb = 77.5 ° C-76.72 ° C = 0.78 ° C
[tex]\rm m=\dfrac{\Delta Tb}{Kb}\\\\m=\dfrac{0.78}{5.03}=0.155[/tex]
then :
[tex]\rm m=\dfrac{mol}{kg~solvent}\\\\m=\dfrac{mass/Mw }{kg~solvent}\\\\0.155=\dfrac{1.42/Mw}{0.05}\\\\0.00775=1.42/Mw\Rightarrow Mw=183.23~g/mol[/tex]

4. which of the following is a molecular geometric shape
Answer:
I need the picture plsss
5. Explain how you used the molecular shapes to predict molecular polarity.Support your answer
Explanation:
To predict molecule polarity from the shapes, you must first see if the molecule has exactly two atoms. If so, subtract the electronegatives to decide if it's polar. If the molecule has unshared electron pairs on the center atom (bent, triagonal pyramidal), the molecule is polar.

8. familiarize with the different molecular shapes?
Answer:
The five ideal shapes are: linear, trigonal planar, tetrahedral, trigonal bypramidal and octahedral. One important point to note about molecular shape is that all diatomic (compounds with two atoms) compounds are linear.

11. 4. Based on the molecular geometry, the structure or shape of a molecule can be symmetrical or asymmetrical. When is molecular shape symmetrical and asymmetrical?
Answer:
If the atoms in the molecule are symmetrical, the charges are balanced by each other. The molecules are considered to be nonpolar. However, if the molecule is asymmetrical, it is considered to be polar. So if it is lopsided, it is polar.
12. Based on the molecular geometry,the structure or shape of molecule can be symmetrical or asymmetrical.when is molecular shape symmatrical and asymmetrical?
Answer:
A symmetrical molecule is one whose appearance does not change if you turn it about an axis of symmetry; original and rotated states are indistinguishable from one another. By contrast, an asymmetrical molecule has no axis of symmetry; you can tell if it has been rotated.
