This is statement can be:
A fact
A truth
A sentense
There you go. I gave you a image.
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
I think the correct answer would be negative change in enthalpy, low temperature and negative entropy. Freezing of water is an exothermic process which means heat is released to the surroundings so negative enthalpy. And this is seen in the change to a lower temperature. Entropy is negative which signifies that there is more order as water freezes.
Answer:
The voltage is
Explanation:
Since the main source of is the sea water then
The equation for the reaction in sea water would be
that is the ion would form a molecule and then release an electron
For river water
I.e the molecule would gain an electron and forms an ion
Now acts as reactant for seawater reaction and product for river water
The voltage of the concentration cell at initial stage is
Now at the voltage for the cell with concentration difference between sea water and river water is mathematical denoted as
Where is the number of electron = 1
So substituting values we have
Removing the negative sign
