The arrangement of particles that make up an ionic compound would be an ionic lattice type of crystal arrangement. An ionic lattice type of structure will be formed due to many of the ionic bonds formed between the oppositely charged ions of the metal and nonmetal.
<span>Mutation. Either exchanging a Purine with another Purine, Pyrimidin with another Pyrimidin, or completely exchanging a Purine with a Pyrimidin or vice versa. Point- or Frameshift-Mutation.</span>
The reason lies within the uniqueness of carbon's structure and bonding capabilities. Carbon has four valence electrons and therefore makes four separate covalent bonds in compounds.
Answer:

OH
- The developed structural formula is also attached.
Explanation:
The IUPAC name, <em>2-hydroxypropanoic acid</em>, lets you predict the structural formula for <em>lactic acid</em>.
- <em>2-hydroxy</em> means that there is a OH functional group attached to the second carbon atom of the chain.
- <em>Propan</em> prefix means that the molecule has 3 carbon atoms.
- <em>oic</em> suffix means that it is a carboxylic acid, this is it contains the COOH functional group.
Hence, in conclusion the structural form of lactic acid is:
|
OH
I used the superscripts just to show the number of the carbon atom in the chain.
The formal structural formula does not contain such superscripts it is just:
|
OH
A more developed structural formula will show the distribution of the atoms in the space. I have also attached a picture with the developes structural formula.
We know, acceleration = change in velocity / time
a = 9.6 - 12 / 0.9
a = -2.4 / 0.9
a = -2.67
In short, Your Answer would be Option C
Hope this helps!
