The answer for this question would be B. Both elements, one being a Group 1 and the other being a Group 17, want to attain the octet of electrons in the outermost shell for chemical stability. The Group 1 element has one too many electrons, and the 17 is lacking one. To increase the stability of the system, the Group 1 can donate the extra electron to the Group 17 so that both can emulate a stable octet. In doing so, two ions are produced (elements that have a net charge that isn’t 0), and thus we have an “ionic bond.”

Hope this helps!

Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger and may fracture, or break, the rock.

Use the table of standard entropy values to determine ΔSºreaction for the following reaction:
TEA [102]

Standar molar entropies from a table:

CH3OH (l): 126.8 J / K*mol
O2 (g): 205.1 J/ K*mol
CO2(g): 213.7 J/K*mol
H2O(g): 188.8 J/J*mol

Now use the coefficients of the reaction and sum the product entropies less the reactant entropies:

4*188.8 + 2*213.7 - 3*205.1 - 2* 126.8 = 313.7 J/mol*K

Answer: option C) +3173.766 J/mol*K
