Answer:
Organisms that belong to the same species, form groups, and interact together in the same environment make the level of the population whereas a community has groups of different species living together in an environment. Species are the group of individuals that are genetically related to each other.
Answer:
draw the carbon chain is containing 6 carbon then attach the aldehyde group with edge carbon in chain then put the put double bond at 3 no. carbon
Answer:
Resonance structures for the nitrate ion exist because there are more than one Lewis Structures for this ion.
Explanation:
How many bonds in each nitrate ion?
To answer this question, start by considering how many electrons each atom need for an octet.
- Each N atom needs three electrons to achieve an octet.
- Each O atom need two electrons to achieve an octet.
The three O atoms and one N atom in each nitrate ion will need electrons in total to be stable. However, the ion carries a charge of . In other words, atoms in the ion have already acquired one extra electron. Now they need only electrons.
Atoms share electrons by forming bonds. In effect, each chemical bond (a pair of shared electrons) adds two electrons to the bonding atoms. Atoms in the nitrate ion will form chemical bonds.
However, there are only three bonding position available. One of the three positions will see a double bond while each of the other two will see a single bond. However, the double bond can be at any of the three bonding position. There are thus three possible Lewis Structures. See the sketched. Note that the three structures are interconvertible by moving only the electrons but not any atoms. Hence the name resonance structures.
Keep in mind that in reality, the pi electrons from the double bond are delocalized across all three possible bonding positions. All three N-O bonds are of equal length.
Answer:
All of these properties are due to the chemical structure of the compound. The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable.
Explanation:
H-F because it has the largest difference in electronegativity which is 2, so it’s the most polar.
