Answer:
a. The longest chain is chosen incorrectly.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to firstly draw the structural formula of the 1,3-Dimethylbutane:
Thus, we can see that the correct name should be 3-methylpentane since the longest chain was chosen incorrectly, as it must have five carbon atoms.
Regards!
<u>Answer:</u> The value of for the chemical equation is
<u>Explanation:</u>
For the given chemical equation:
To calculate the for given value of Gibbs free energy, we use the relation:
where,
= Gibbs free energy = 78 kJ/mol = 78000 J/mol (Conversion factor: 1kJ = 1000J)
R = Gas constant =
T = temperature = 1000 K
= equilibrium constant in terms of partial pressure = ?
Putting values in above equation, we get:
Hence, the value of for the chemical equation is
Moles neutralized = moles
neutralized at the equivalence point of a titration. Hence, option A is correct.
A method or process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution.
Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution.
At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.
Hence, option A is correct.
