Which model of acids and bases would NOT define NH3 as a base (even though it is considered one by the other models)?
prohojiy [21]

Answer:

<em>The correct option is A) Arrhenius</em>

Explanation:

According to the Arrhenius concept of acids and bases, an acid must produce H+ ions when it is present in a solution and the base must produce OH- ions when placed in a solution.

Ammonia does not contain OH- ions of its own when dissolved in water.

The reaction of ammonia dissolving is water can be written as:

NH3     +    H2O     ⇌   NH4+ + OH−

As we can see from the equation, ammonia does form OH- ions but it does not have OH- ions on its own.

Hence, according to the Arrhenius concept, NH3 is not a base.

From the following balanced equation,
ArbitrLikvidat [17]

Answer:

9.72 grams.

Explanation:

From the equation, 4 moles of NH₃ produce 6 moles of  water.

Therefore the reaction to product ratio of  NH₃ to H₂O is 4:6

and 2:3 into its simplest form.

The number of moles of NH₃ in 6.12 g is:

Number of moles=mass/ RMM

=6.12 g/17 G/mol

=0.36 moles.

Therefore the number of moles of H₂O produced is calculated as follows.

(0.36 Moles×3)2 = 0.54 moles

Mass= Number of moles × RMM

=0.54 moles×18g/mol

=9.72 grams.
