Option 4. ratio of electrons to protons
Isotope that has atomic number of 82 is stable. An element that has an atomic number ∠82 more stable except Tc and Pm. Also there is the concept that isotopes consisting a combination of even-even,even-odd,odd-even, and odd-odd are all stable. Many isotopes with no magic numbers of nucleons are stable
The Nernst equation allows us to predict the cell potential for voltaic cells under conditions other than the standard conditions of 1M, 1 atm, 25°C. The effects of different temperatures and concentrations may be tracked in terms of the Gibbs energy change ΔG. This free energy change depends upon the temperature & concentrations according to ΔG = ΔG° + RTInQ where ΔG° is the free energy change under conditions and Q is the thermodynamic reaction quotient. The free energy change is related to the cell potential Ecell by ΔG= nFEcell
so for non-standard conditions
-nFEcell = -nFE°cell + RT InQ
or
Ecell = E°cell - RT/nF (InQ)
which is called Nernst equation.
<span>1. The two qualities used to describe winds are direction and speed.
2. a local wind that blows during the day from an ocean toward land is a(n) sea breeze.
3. The increase in cooling that wind can cause is called the wind-chill factor.
4. Temperature differences between the equator and poles produce convection currents.
A movement that is parallel to Earth's Surface is called wind and a local wind is that wind that blows over a short distance.</span>
Multiple by 2 because it was give u right answer
