answer: dispersed from the liquid so cold air can take its place
The fridge part can, just not the freezer, I think.
Hello Gary My Man!
Well, as you can clearly see
<span>The atomic number of an element is basically the number of protons it has. So yes, for every element this is different. Now, the mass number of an element as known, is the number of protons+the number of neutrons. So theoretically as we can see, this number should be a whole number, but since there are different isotopes (atoms of the same element with different numbers of neutrons) of each element, most periodic tables take account of that, so they often include decimals as seen.
So in Short, ALL</span> the atoms of a particular element have the SAME EXACT atomic number<span> (</span>number<span> of protons of course). The </span>atoms of different elements have very different numbers of protons. And of course, the MASS number of an atom is the TOTAL number as known, of protons and of course, the neutrons it contains in it.
I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)

Answer : The
for this reaction is, -88780 J/mole.
Solution :
The balanced cell reaction will be,
![Cu(s)+2Ag^+(aq)\rightarrow Cu^{2+}(aq)+2Ag(s)](https://tex.z-dn.net/?f=Cu%28s%29%2B2Ag%5E%2B%28aq%29%5Crightarrow%20Cu%5E%7B2%2B%7D%28aq%29%2B2Ag%28s%29)
Here, magnesium (Cu) undergoes oxidation by loss of electrons, thus act as anode. silver (Ag) undergoes reduction by gain of electrons and thus act as cathode.
The half oxidation-reduction reaction will be :
Oxidation : ![Cu\rightarrow Cu^{2+}+2e^-](https://tex.z-dn.net/?f=Cu%5Crightarrow%20Cu%5E%7B2%2B%7D%2B2e%5E-)
Reduction : ![2Ag^++2e^-\rightarrow 2Ag](https://tex.z-dn.net/?f=2Ag%5E%2B%2B2e%5E-%5Crightarrow%202Ag)
Now we have to calculate the Gibbs free energy.
Formula used :
![\Delta G^o=-nFE^o](https://tex.z-dn.net/?f=%5CDelta%20G%5Eo%3D-nFE%5Eo)
where,
= Gibbs free energy = ?
n = number of electrons to balance the reaction = 2
F = Faraday constant = 96500 C/mole
= standard e.m.f of cell = 0.46 V
Now put all the given values in this formula, we get the Gibbs free energy.
![\Delta G^o=-(2\times 96500\times 0.46)=-88780J/mole](https://tex.z-dn.net/?f=%5CDelta%20G%5Eo%3D-%282%5Ctimes%2096500%5Ctimes%200.46%29%3D-88780J%2Fmole)
Therefore, the
for this reaction is, -88780 J/mole.
Answer: The force of attraction occurring between two masses.
