Which kind of intermolecular force attracts the stearate ion to the oil drop?a. Debye (induced dipole) forcesb. hydrogen bonding

c. dipole-dipoled. dispersion forces

Answer:

d.  dispersion forces

Explanation:

Dispersion forces -

It is a very weak type of interaction observed between two atoms , when the electrons of the respective atoms  attain a position where they form temporary dipoles , is referred to as dispersion forces.

These are the temporary force of attraction.

These force of attraction are also referred to as induced dipole-induced dipole attraction .

These force of attraction are possible when the electrons are unsymmetrically distributed thereby induces positive and negative poles.

Similarly ,

Stearate ion and oil drop have dispersion force between them.

Wittaler [7]

Answer:

a,c and d are exothermic

b is the endothermic

Explanation:

exothermic because energy required to form products is less than the energy required to break bonds in reactants.

endothermic because energy required to form products is larger than the energy required to break bonds in reactants.

Aphelion in miles =94290301

Perihelion in miles = 91200281

Explanation:

To convert km in mile we use the multiply the distance in km with 0.62, because there are 0.62 miles in 1 km.

Aphelion in miles = aphelion in km × 0.62

Aphelion in miles = 152081132 × 0.62

Aphelion in miles =94290301

Perihelion in miles = perihelion in km × 0.62

Perihelion in miles = 147097229 × 0.62

Perihelion in miles = 91200281

What are the benefit of understanding physical properties?
klasskru [66]
Physical properties help identifying a substance and how it changes.
For example: if a substance crushes easily that means it has a low density, but if it’s hard and doesn’t crush easily, that means it has a strong high density.
And eventually the substance would not end up forming a new substance.
Look at the picture below to understand more about physical changes.

Draw the structure of cis-4-nonene. Now describe the structure you have drawn:
Nadya [2.5K]

Answer:

2D structure is based on skeletal formula and

3D structure is based on ball and rod model

Explanation:

Please find the attached image of 2 D and 3 D structure of cis-4-nonene

The 2D structure of Cis-4 nonene  resembles the shape of skeletal formula. Almost every organic molecule has notation of skeletal formula. Each carbon atom is connected to sufficient number of hydrogen atom so that the valence of each carbon atom is satisfied.  

The carbon atom is located at the corner while the hydrogen atom are not indicated.  

The three dimensional structure of Cis-4 nonene   is based on stick and ball model where ball represents the various types of atoms and the rod length  represents the bond. White ball represents the hydrogen atom and grey ball represents the carbon atoms.
