Answer:
The change in the Gibbs function of reaction on going from crust to core, dG=291442.4 J/mol
Explanation:
dG=vdp-sdT
Where T is the temperature .
P is the pressure.
S is entropy
V= 1cm3 =10-6 m3
P= 3*10∧6 atm = 3*10∧11 pa
The temperature at the center of the earth, Tc = 4*103 °C. : The temperature at the sufrace (crust) of the earth, Ts =298K.
Subistuting the values
dG = (10-6 *(3*1011-105) - (2.1(4373-298))
dG=291442.4 J/mol.
Answer:
0.00915 M of remain after 5.16 seconds.
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = s⁻¹
Initial concentration = 0.054 M
Final concentration = ? M
Time = 5.16 s
Applying in the above equation, we get that:-
<u>0.00915 M of remain after 5.16 seconds.</u>
Answer:
Matter in its solid state has the lowest amount of thermal energy (for that type of matter). Because solids have less thermal energy than liquids or gasses, the atoms in their solid state move very little.
HOPE THIS HELPED!!!!!!!XDDDDD
Answer:
More than three decade the temperature of earth is increasing equally by the rate of 0.8 Celsius (1.4 Fahrenheit). It is going to be very harmful for the human being as well animals. The global warming is the main reason and hole in the ozone layer had been the cause of increasing the temperature of the earth. Humans are also involved in cause in temperature of earth by cutting forests and making land suitable for residence and not planting more trees instead of the cut trees.
Here are the answers. A,A,A,C,A,C.
I hope this helps!
