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.
Answer:
<h2>Density = 5.24 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass = 52.4 g
volume = 10 cm³
Substitute the values into the above formula and solve for the density
That's
<h3>
</h3>
We have the final answer as
<h3>Density = 5.24 g/cm³</h3>
Hope this helps you
Answer:
Y>Q>W>Z>X
Explanation:
Each more reactive element on the list replaces from a compound any of the elements below it (less reactive).
Q>W
Z>X
W>Z
Y>Q
Thus,
Y>Q>W>Z>X
Answer:
d. adding an inhibitor
c. fish that emit light
c. released
Explanation:
An inhibitor is a negative catalyst. It is usually a substance that slows down the rate of chemical reaction.
Chemical inhibitors acts in way that makes reactions drags over time.
Increasing temperature, increasing concentration and decreasing particle size all will increase the rate of chemical reaction. They make reactions proceed more faster.
When a fish emits light, it is not an exothermic reaction.
An exothermic reaction is one in which heat is released to the environment. In such reactions, heat is liberated to the surroundings. At the end of the reaction, the surrounding will have a higher temperature compared to the reaction.
We assign exothermic reactions a negative value because the sum of heat contents of products is less than that of reactants.
