what does it mean when the h3o+ to x- distance doesn't change much as the first 4 to 5 water molecules are added

podryga [215]

If X is an equivalent base to H₂O
HX is an equivalent acid to H₃O⁺
HX is a stronger acid than H₃O⁺
HX is not an acid
X⁻ is a stronger base than H₂O
HX is a weaker acid than H₃O⁺
X⁻ is a weaker base than H₂O
X⁻ is not a base.

The correct response or this is
X⁻ is a stronger base than H₂O
HX is a weaker acid than H₃O⁺

How many moles of Al will be consumed when 0.400 mol of Al2O3 are produced in

Vladimir [108]

Answer:

C) 0.800 mol

Explanation:

4Al + 3O₂ → 2Al₂O₃

In order to <u>convert from moles of Al₂O₃ into moles of Al</u>, we'll need to use<em> the stoichiometric coefficients</em>, using a conversion factor that has Al₂O₃ moles in the denominator and Al moles in the numerator:

0.400 mol Al₂O₃ * $\frac{4molAl}{2molAl_2O_3}$ = 0.800 mol Al

So the correct answer is option C).
