Answer:

A. Intramolecular interactions are generally stronger.

B. a. Only intermolecular interactions are broken when a liquid is converted to a gas.

Explanation:

<em>A. Which is generally stronger, intermolecular interactions or intramolecular interactions?</em>

Intramolecular interactions, in which electrons are gained, lost or shared, constitute true bonds and are one or two orders of magnitude stronger than intermolecular interactions.

<em>B. Which of these kinds of interactions are broken when a liquid is converted to a gas?</em>

When a liquid vaporizes, the intermolecular attractions are broken, that is, molecules get more separated. However, true bonds are not broken which is why the molecules keep their chemical identity.

What are the equilibrium partial pressures of pcl3 , cl2, and pcl5, respectively? express your answers numerically in atmosphere
aliina [53]
The question is incomplete, so I tried to find a similar problem online. It is shown in the attached picture. The reaction is

PCl₃ + Cl₂ ⇆ PCl₅

Then, we use the ICE (Initial-Change-Excess) approach as follows:

        PCl₃ + Cl₂ ⇆ PCl₅
I        0.5      0.5      0.3
C      -x         -x        +x
E    0.5-x    0.5-x    0.3+x

Total pressure: 0.5 - x + 0.5 - x + 0.3 + x = 1.3 

Kp = [PCl₅]/[PCl₃][Cl₂]
0.18 = (0.3+x)/(0.5-x)²
Solving for x,
x= 0.21

Partial pressures would be:
<em>PCl₃ = 0.5 - 0.21 = 0.29 atm</em>
<em>Cl₂ = 0.5 - 0.21 = 0.29 atm</em>
<em>PCl₅ = 0.3+0.21 = 0.51 atm</em>

What is the purpose of writing Shorthand Electron Configuration Using Noble Gases?<br> 30 POINTS!
aivan3 [116]

The noble gas configuration system helps to shorten the total electron configuration by using the symbol for the noble gas that lies before the particular element in the periodic table.  

For example:

Na has atomic number 11

Electron configuration of Na: 1s2 2s2 2p6 3s1

Noble gas electron configuration of Na: [Ne] 3s1

Ne has atomic number 10 and lies before Na in the periodic table.

<h3>What is a Chemical Reaction ?</h3>

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.

Substances are either chemical elements or compounds.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Chemical reactions are an integral part of technology, of culture, and indeed of life itself.

The product that is formed is shown in the figure , Option A is the correct answer , and the highlighted carbons shown corresponds to the carbons from diethyl malonate.
