Explanation:

To find the amount of product that would be formed from two or more reactants, we need to follow the following steps;

Find the number of moles of the given reactants.
Then proceed to determine the limiting reactant. The limiting reactant is the one in short supply which determines the extent of the reaction.
Use the number of moles of the limiting reactant to find the number of moles of the product.
Then use this number of moles to find the mass of the product

Useful expression:

Mass = number of moles x molar mass

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

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.
