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 )
Answer:
180 p
Explanation:
Energy refers to the capacity of doing work.
Amount charged by an electrical company = 15 p per unit of energy (kWh)
As 1 W = 1000 kW,
Also, 1 day = 24 hours.
Cost of running a 500 W freezer = 0.5 kW freezer for 1 hour =
Therefore,
cost of running a 0.5 kW freezer for a day ( 24 hours ) =
Amount charged by an electrical company = 15 p per unit of energy (kWh)
As 1 W = 1000 kW,
Also, 1 day = 24 hours.
Cost of running a 500 W freezer = 0.5 kW freezer for 1 hour =
Therefore,
cost of running a 0.5 kW freezer for a day ( 24 hours ) =
There are more oxygen atoms in the reactants while there are less oxygen atoms in the product.
Both sides of the equation is supposed to be balanced for a balanced equation. If any one of them isn't balanced, the equation remains unbalanced.
The main reason why the reaction above can not be balanced is:
This chemical reaction SO2 + H2O -> H2SO2 is not correctly written.
It must be: SO2 + H2O -> H2SO3

Hi,
The answer should be letter C, since a compound is made of atoms of two or more elements, in a defined ratio, bonded together.
In ridge push, the mantle wells upward because of the
convection and elevates the edges of spreading oceanic plates. Because these
plates are higher at the spreading center, they are forced downhill due to
<em>gravity</em> and eventually flatten out to the ocean floor.
