How many isomers of dichloroethylene have a zero dipole moment?

2 answers:

8 0

There are three isomers of dichloroethylene, they are 1,1 dichloroethylene, cis 1, 2- dichloroethylene and trans 1, 2 -dichloroethylene. Trans 1, 2 - dichloroethylene is non-polar and has a zero dipole moment while the other two isomers are polar.

There are three dichloroethylen isomers: 1,1, dichloroethylene; 1,2 cis dichloroethylene and 1,2 trans dichloroethyelene.

1,1 dichlorothylene have two Cl - C dipoles on the same side of the molecule and they do not cancel each other, so this isomer has a net dipole moment.

1,2 cis dichloroethylene has two Cl - C dipoles on the same plane so they do not cancel each other, and this isomer also has a net dipole moment.

1,2 trans dichloroethylene has two Cl - C dipoles on different planes and they cancel each other. So this isomer has a zero dipole moment.

The answer is that one isomer of dichloroethylene has a zero dipole moment.

Draw the Lewis structures for CH3OH, CH2O and HCOOH. Indicate the hybrid orbital used in the sigma bonds for each of the carbon

sdas [7]

Answer:

See figure 1

Explanation:

For this question, we have to remember that in the lewis structures all atoms must have 8 electrons. And each atom would have a different value of valence electrons:

Carbon => 4

Oxygen=> 6

Hydrogen=> 1

Additionally, for the hybridizations we have to remember that:

$Sp^3$ => 4 single bonds

$Sp^2$ => 1 double bond

$Sp^1$ => 1 double bond

With this in mind, the formaldehyde and formic acid would have $Sp^2$ carbons and the ethanol an $Sp^3$ carbon.

Finally, for the oxidation state. We have to remember that if we have more bonds with oxygen, we will have more oxidation. Therefore, the carbon that has more oxidation is the one in the formic acid (we have several bonds with oxygen).

See figure 1

I hope it helps!

KCIO3 → KCI + O2

First you have to count all the atoms of each element in both sides of the reaction, in this case:
Left side: there is one K atom, one Cl atom and 3 O atoms
Right side: there is one K atom, one Cl atom and 2 O atoms

K and Cl are balanced but O isn't
To balance O you can add a coefficient to O2 in the right side of the equation like this:

KCIO3 → KCI +3 O2

Now you have 6 oxygen atoms in the right side but only 3 in the left side, so you can add a coefficient to KClO3:

2KCIO3 → KCI +3 O2

And finally, Balance K and Cl again by adding a 2 as a coefficient for KCl

2KCIO3 → 2KCI +3 O2

Now both sides have the same amount of atoms of each element (2 K atoms, 2 Cl atoms and 6 O atoms)

what concept from chemistry was the most challenging and why? what can you do to learn more about this concept as you progress t

qwelly [4]

The most difficult concept will be the concept of patient drug tolerance because there are many drugs that have different side effects for different patients. Therefore, it is necessary to understand the response of certain drugs to different patients. This will help avoid wrong drug combinations. This can cause side effects.

To learn more about this concept, you need to do your homework on these different drugs and the tolerance reactions you may experience, and attend some drug tolerance seminars, where the speaker will give you more ideas . And a further explanation of the concept.

Another topic in chemistry that is most tough to understand is moles. We can understand this concept by understanding the fact mole is an amount of a substance which may be atoms, molecules, ions, etc which have exactly 6.02214076 * 1023 'elementary entities' of the substance.

I would say a Think Tank would be the best creative process to help engineers generate ideas. Think Tanks are groups of people that help generate ideas to solve problems and grow companies.

Can someone show me a step by step with the answer?

Georgia [21]

Answer:

6 mols HCl

Explanation:

(I'm an AP chemistry student but not perfect at this stuff)

you can use the Molarity=Moles/L equation here:

(6M)=(moles HCl)/(1L)

divide by 1 on both sides to isolate the moles of HCl

this gets you 6 moles HCl.

Again I'm just a student so my answer might be wrong, but this question should just require the M=mols/L equation :).
