Aluminum forms a layer of aluminum oxide when exposed to air which protects the bulk metal from further corrosion. 4 al(s) + 3 o2(g) latex: \rightarrow → 2 al2o3(s) using the thermodynamic data provided below, calculate latex: \delta δs° for this reaction.

How much energy moves onto the next level, in an energy pyramid

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
