Calculate ΔG ° for the following reactions at 25 ° C: a) 2Mg (s) + O2 (g) → 2MgO (s); b) 2SO2 (g) + O2 (g) → 2SO3 (g); c) 2C2H6 (g) + 7O2 (g) → 4CO2 (g) + 6H2O (l)

NOPE

Explanation:

DAT IS TO HARD! WATCH SOME TIKTOK!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i would say b

explanation:

but i think i would need more information than that
