Answer:The value of rate constant is .
Explanation:
Concentration of [A]=0.10 mol/L
The rate of the reaction =
Rate constant = k
The given rate law:
The value of rate constant is .
Given:
rate = k [A]2
concentration is 0.10 moles/liter
rate is 2.7 × 10-5 M*s-1
Required:
Value of k
Solution:
rate = k [A]2
2.7 × 10-5 M*s-1 = k (0.10 moles/liter)^2
k = 2.7 x 10^-3 liter per mole per second
Explanation:
It is known that formula for area of a sphere is as follows.
A =
=
= 3.14
= (27 + 273.15) K = 300.15 K
T = (77 + 273.15) K = 350.15 K
Formula to calculate the net charge is as follows.
Q =
where, e = emissivity = 0.85
s = stefan-boltzmann constant =
A = surface area
Hence, putting the given values into the above formula as follows.
Q =
=
= 1046.63 W
Therefore, we can conclude that the net flow of energy transferred to the environment in 1 second is 1046.63 W.
B. Atomic nuclei possess shells similar to the electron shells of atoms.
C. Some atoms contained more protons than electrons.
The answer is:
Sublimation
The explanation:
The most state has the high volume is the gas state.
So here the answer is between vaporization and sublimation???
and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas
and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°
here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
Answer: The correct answer is Option 4.
Explanation:
All these processes are the physical processes which occurs between the phases of matter.
Solid state is the phase where particles are closely arranged and the volume of this state is less.
Liquid state is the phase where particles are not closely arranged and the volume of this state is more than solid but less than gaseous state.
Gaseous state is the phase where particles are loosely arranged and this state has the largest volume.
Hence, the correct answer is Option 4.
