Answer:

Kw = 1×10⁻¹⁴

Explanation:

The product between the [H₃O⁺] .  [OH⁻] talks about the

autoionization of water.

2H₂O  ⇄  H₃O⁺  .  OH⁻     Kw

This is an equilibrium of 2 molecules of water that produces 1 mol of hydronium and 1 mol of hydroxides.

In order to determine pH and pOH, parameters to indicate acidic or basic solutions we know:

- log [H₃O⁺] = pH

- log [OH⁻] = pOH

When [H₃O⁺] or [OH⁻] = 1×10⁻⁷ , pH or pOH = 7 (Neutral solutions)

So if we see the equation above, we have an equilibrium.

In order to determine Kw, we need [H₃O⁺] .  [OH⁻]

As [H₃O⁺] and [OH⁻] = 1×10⁻⁷ , Kw = 1×10⁻¹⁴

For which of the following reactions are both reactants and products likely to be found when the reaction appears to be complete
Scorpion4ik [409]
The answer is
<span>HF + H2O <--> H3O(+) + F(-)
</span>
<span>HF + H2O gives  H3O(+) + F(-)
and </span>
 H3O(+) + F(-) gives <span>HF + H2O
it is a reciprocal reacation, so </span>
<span>reactions are both reactants and products </span>

How much mass (in grams) is in a 3.25 mol sample of NH4OH?
Sergeeva-Olga [200]

Answer:

114 grams

Explanation:

1. NH4OH molecular weight: The molar mass of NH4OH = 35.0458 g/mol...

2. Convert grams-NH4OH-to-moles or moles-NH4OH-to-grams. Molecular weight calculation: 14.0067 + 1.00794*4 + 15.9994 + 1.00794.
