Consider the equilibrium
At 1000 K and a const. total pressure of 2 bar, C2H6 is introduced into a reaction vessel. the total pressure is held const. at 2 bar and at equilibrium the composition of the mixture in mole percent is H2(g): 20.4%, C2H4 (g): 20.4%, and C2H6 (g): 59.2%.
Calculate Kp at 1000 K
if ΔH of reaction = 137 kJ/mol, calculate the value of Kp at 298.15K
Calculate ΔG of reaction for this reaction at 298.15 K

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
