Rather hard to represent 3-d depictions of molecular structures on a 2-d surface short of folding the paper.
That's around all otherwise it is a simple and common way to depict chemical structures
Lewis dot Structures and Covalent bonds are completely different. The Lewis dot takes or gives, while covalent bonds share.

What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
Which instrument would be best for the scientist to use to take a picture of the well-ordered arrangements of he atoms and molecules within a substance?
A high-resolution transmission electron microscope (TEM) would be the best instrument to use for imaging the well-ordered arrangements of atoms and molecules within a substance. TEM offers the necessary resolution to visualize atomic and molecular structures at a very fine scale.

What best describes how molecules interact with systems in the human body?
you need the molecules to make the tissue.
What element is best able to combine with itself and hydrogen to form large molecules?
Carbon is best able to combine with itself and hydrogen to form large molecules due to its ability to form strong covalent bonds with other carbon atoms and hydrogen. This allows for the formation of diverse carbon-based structures such as hydrocarbons, polymers, and complex biomolecules.
In chemistry what is a resonance?
A resonance structure is an alternate way of drawing a Lewis dot structure for a compound. For some molecules, there are multiple ways to draw a Lewis dot structure that still satisfy the rules (for instance, having the correct total electron count and satisfying the octet rule on each atom).Benzene is a classic example where a resonance structure is used. See the Web Links to the left for a diagram of benzene's two resonance structures. Note that in both cases, there are alternating double and single bonds between the six carbons. What changes in the two structures is which bonds are single and which are double bonds. In reality, all the bonds in benzene are identical. They are neither single nor double bonds, but something like a "one-and-a-half bond."There is a common misconception that in reality the molecule is somehow alternating between the two structures. It is not.. This is extremely important to understand! Resonance structures are simply a tool to make up for the fact that Lewis dot structures are not the best tool for describing bonding in molecules (they are very good, just not perfect!). Using resonance structures is a kind of band-aid to patch up this shortcoming of Lewis dot structures (for a better representation of bonding, you must use molecular orbital theory which requires quantum mechanics!).So if the is not alternating between the two structures, what's going on?! In fact the molecule's structure is always the same. The actual bonding the molecule is a mixture of the different resonance structures all the time. To see this, you have to look at the different structures and imagine blending them together to give one single structure which has contributions from each structure. So the bonds in benzene are not going back and forth being single and double bonds. Not at all! Not even really quickly. Instead the bonds are ALWAYS this average bond which is a bit of both single and double.Note also that not all resonance structures contribute equally to what the molecule really looks like. For benzene, there are two structures, and the real molecule is a perfect mixture of both structures, 50% each. However, the are some molecules for which you can draw more than a dozen structures! In this case, you might have one structure that is dominant, and the real molecule's structure is close to that, and the other structures only contribute a little bit. In other words, the real structure is a weighted average of all the different resonance structures, but the weighting for each structure depends on the details of that structure, and some have very little weighting.How do you tell what structures are more important that other ones? Only if the structures are identical by symmetry, like for benzene, do they contribute exactly the same amount. Another way to say this is that if you can convert between two structures just by rotating the drawing around, they are the same by symmetry. However, sometimes they are not the same at all. Here is how you tell. A better resonance structure has the following properties:-- bond is maximized-- formal charges are minimized-- negative formal charges are carried by the most electronegative atomsThere is no way to predict exactly how much each structure will contribute (except when two are equal by symmetry). But you can put them in order based on the three rules above (and they are listed in order of importance).
Which equation best represents the dissociation of watermark molecules into hydrogen ions and hydroxide ions?
The dissociation of water molecules into hydrogen ions and hydroxide ions is best represented by the equation: H2O -> H+ + OH-.

What is the difference between resonance and resonant frequency?
resonance is the behavior of resonant frequency while resonant frequency is the cause of it. There are basically two types of resonance; Electrical and Magnetic. Resonant frequency is that particular frequency for a system for which the system performs its best. while the system at that particular situation can be called the system at resonance
Structure of benzene best described?
This is a tough question. Virtually every Organic chemistry teacher will say 2....the two Kekule resonance structures. However....that is incorrect. Benzene also has 4 other minor resonance forms. Mathematical calculations, as well as quantum mechanics have shown conclusively that benzene is not 2 sole resonance canonicals....but the Dewar structures as well. My proof is this....the bond order is not 1.5, as predicted....but rather 1.463. Hope this helps. Dr Jim Romano CEO Romano Scientific CEO Orgoman.com

How many double bonds are present in the best resonance structure of the phosphate ion?
The best resonance structure of the phosphate ion has one double bond and three single bonds. The double bond is between the central phosphorus atom and one of the oxygen atoms.

What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
Which diagram best represents the relative locations of the structures in the list below a-chromosome b-nucleus c-cell d-gene?
The best diagram would show the cell as the outermost structure, enclosing the nucleus, which in turn contains the chromosomes. Genes would be represented as smaller components within the chromosomes.
