Answer:
compaction and cementation.
Answer:
Krypton.
Explanation:
By Graham's Law:
Rate 1 / Rate 2 = sqrt M2 / sqrt M1
Molecular Mass for Neon is 20.18
so we have:
38 / 77.5 = sqrt 20.18 / sqrt x where x is the unkown gas.
sqrt x = 9.162
x = 83.94.
This gas is Krypton.
Gas particles spread out to fill a container evenly, unlike solids and liquids. Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. Hence above statement is FALSE.
Guy-Lussac's Law states that the volume and the temperature are directly proportional given that the pressure remains constant.
For this problem, we will assume constant pressure. Based on the law:
(Volume/Temperatur)1 = (Volume/Temperature)2
(3.75/100) = (6.52/T)
T = 166.667 kelvin
Answer:
![[A_t]=0.037\ M](https://tex.z-dn.net/?f=%5BA_t%5D%3D0.037%5C%20M)
Explanation:
(a)
Given that:
Rate constant, k = 0.0347 min⁻¹
The expression for the half-life is:-
Where, k is rate constant
So,
(b)
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
Where,
![[A_t]](https://tex.z-dn.net/?f=%5BA_t%5D)
is the concentration at time t
![[A_0]](https://tex.z-dn.net/?f=%5BA_0%5D)
is the initial concentration
Given that:
The rate constant, k = 
min⁻¹
t = 60 min
Initial concentration = 0.300 M
Final concentration =?
Applying in the above equation, we get that:-
![[A_t]=0.300\times e^{-0.0347\times 60}\ M](https://tex.z-dn.net/?f=%5BA_t%5D%3D0.300%5Ctimes%20e%5E%7B-0.0347%5Ctimes%2060%7D%5C%20M)
![[A_t]=0.3\times \frac{1}{e^{2.082}}\ M](https://tex.z-dn.net/?f=%5BA_t%5D%3D0.3%5Ctimes%20%5Cfrac%7B1%7D%7Be%5E%7B2.082%7D%7D%5C%20M)
