50.00ml*(10^-3L/ml)*(3.91moles/L) = 0.196 mol
<span>The best and most correct answer among the choices provided by the question is the first choice. The characteristic that is primarily responsible for the existence of the rock ledge is its greater resistance to weathering. I hope my answer has come to your help. God bless and have a nice day ahead!</span>
The values of the changes are
ΔH = 46.44kJ
Δu = 43.34Kj
ΔS = 126.6 J/K
<h3>How to find change in H</h3>
= 1 mol + 75.3 (100 + 273) - 25 + 273 + 1 * 40.79
= 5.6475 + 40.79
= 46.44kJ
<h3>How to find change in S</h3>
1 mol + 75.3 x ln 373/298 + 1 mol x 40.79
= 0.1263
ΔS = 126.6 J/K
<h3>How to find the change in U</h3>
46.44 - 0.00831 * 373
= 43.34Kj

If a neutral element has 4 electrons in its
4P shell then its electron configuration is 1S2 2S2 2P6 3S2 3P6 3D10 4P4. therefore the sum of electrons = 2+2+6+2+6+10+4=32 electrons
since the element is neutral, so number of electrons = number of protons. hence number of protons that element has is 32
the only element that has 32 protons is germanium
so the answer is Ge
