Explanation:
Fractional distillation is used to separate crude oil into simpler, more useful mixtures . This method can be used because different hydrocarbons have different boiling points

Answer:
A. 3A + 2D → 2C + F
B. B is an intermediate
C. rate = k[A]³
D. rate = k`[D]²
Explanation:
Part A
The overall reaction is the sum of all the elementary steps:
3A→B+C
+
B+2D→C+F
<u> </u>
3A + 2D → 2C + F
Part B
A reaction intermediate is one that participates in the elementary steps, but it is not a product. Notice B is produced in the first step and consumed in the second, therefore it is an intermediate species.
Part C
The rate law is the product of the reaction constant, k, times the concentration of the reactants raised to the power of their coefficients in the balanced reaction assuming that it is the slow step in the reaction mechanism.
rate = k[A]³
Part D
Again as in part C:
rate = k [D]² ( B is not included since as we saw it is an intermediate )
Experiments with cathode ray tubes led to the discovery of the electron (electrons).

Hey there!
There are 1000 mL in a liter.
1.4 L + 0.045 L = 1.445 L
In total there is 1.445 L of the solution.
To find the percent of isopropyl alcohol, divide the amount of isopropyl alcohol by the total amount.
0.045 ÷ 1.445 = 0.0311
Convert to a percent.
3.11%
Hope this helps!
