Answer:

Explanation:

Hello,

In this case, given the properly balanced reaction:

$CH_3OH+\frac{3}{2} O_2\rightarrow CO_2+2H_2O$

If 8.0 moles of methanol react, we can compute the produced grams of water by noticing the 1:2 molar ratio between them in the chemical reaction (stoichiometric coefficients):

$n_{H_2O}=8molCH_3OH*\frac{2molH_2O}{1molCH_3OH} \\\\n_{H_2O}=16molH_2O$

Best regards.

The activity series goes top to bottom, most active to least active elements, going: Li, K, Ba, Sr, Ca, Na, Mg, Mn, Zn, Fe, Cd, Co, Ni, Sn, Pb, H, Cu, Ag, Hg, Au.

Thus, your list of metals would go from most reactive to least reactive: Li, K, Mg, Zn, Fe, Cu, Au
