which particle diagram shown above best represents the strongest intermolecular force between two ethanol, c2h6o, molecules?

Answers

Answer 1

The strongest intermolecular bonding in ethanol is hydrogen bonding.

Intermolecular forces are the forces that hold two molecules of a substance together in a given state of matter. For ethanol, the strongest intermolecular force is hydrogen bonding.

Hydrogen bonding occurs when hydrogen is directly linked to a highly electronegative element such as oxygen, nitrogen, fluorine or sulfur. The existence of intermolecular hydrogen bonds accounts for unusual properties such as abnormally high melting and boiling points.

Answers

diamond for example, will not conduct electricity as there are no mobile ions or electrons to carry electric charge. all the electrons in the carbon atoms in diamond are used for covalent bonding.

why does hydrogen fluoride have a high boiling point

Answers

The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.

for the reaction 2nh3(g)↽−−⇀ 3h2(g)+n2(g), if 15.8 grams of ammonia produced 1.87g of hydrogen, what was the percent yield

Answers

Answer:

75%

Explanation:

So, the reaction will consume 1 mole of hydrogen gas and produce

1mole H2⋅2 moles NH33moles H2=0.667 moles NH3

at 100% yield. This represents the reaction's theoretical yield.

Now, you know that the reaction produced 0.50 moles of ammonia. This represents the reaction's actual yield.

In order to find the percent yield, you need to figure out how many moles of ammonia are actually produced for every 100 moles of ammonia that could theoretically be produced.

You know that 0.667 moles will produce 0.50 moles, so you can say that

100moles NH3.in theory⋅0.50 moles NH3.actual0.667moles NH3.in theory=75 moles NH3.actual

Therefore, you can say that the reaction has a percent yield equal to

% yield = 75%

What is an energy level?

Electrons present in an atom revolve in different orbits which are stationary states and are also called as energy levels. The energy levels are numbered as integers which are also called as principal quantum numbers.

Energy of the stationary state is given as E= -R

1/n² where R

is the Rydberg's constant. When an electron is excited, and it moves from lower to higher energy levels there is absorption of energy, while when it moves from higher energy level to lower energy level it radiates or gives out energy in the form of radiation.

They can also be defined as the distances between electron and nucleus of an atom . Electrons present in K energy level have least energy .Energy level diagrams are studied to understand nature of bonding , placement of electrons in orbits and and elemental behavior under certain conditions.

What is Covalent bonding?

Covalent bonding may be defined as a type of chemical bonding that may involve the mutual sharing of electrons in order to construct electron pairs between atoms of non-metals. These electron pairs which are formed between atoms are known as bonding pairs or shared pairs.

According to the context of this question, covalent bonds are generally formed between nonmetals. While metallic bonds are the type of chemical bonds which are typically formed between the metallic element.

Another type of bonding may also be formed between elements. This type of bonding is known as Ionic bonding. This chemical bonding mat generally arises between metals and non-metals.

4568/1.3 = 3513.84615

Now let's change the answer in sig figs.

We know that trailing zeros don't actually count as part of sig figs.

If the difference between the electronegativities of the two atoms is small, neither atom can take the shared electrons completely away from the other atom and the bond will be covalent.
