What is the error? NH4OH (aq) + KOH (aq) --> KOH (aq) + NH4OH (aq)

Answer:

  • <u>There is not a chemical reaction. This is just the dissolution of two ionic compounds that remain dissolved in solution, without reacting.</u>

Explanation:

The issue here is that none chemical reaction is happening.

The two compounds mixed are ionic bases: both of them dissociate in water producing OH⁻ ions:

  • NH₄OH (aq) → NH₄⁺(aq) + OH⁻(aq)

  • KOH (aq) → K⁺(aq) + OH⁻(aq)

Then, when you write the total ionic equation you have:

NH₄⁺(aq) + OH⁻(aq) +  K⁺(aq) + OH⁻(aq) →

                                                   NH₄⁺(aq) + OH⁻(aq) +  K⁺(aq) + OH⁻(aq)

Look at the species on the reactant side and the product side: the same ions are found on both sides.

That means that all of them are spectator ions: they are just dissolved, and remain in water (aqueous solution) without reacting. None new different compound is formed.

The net ionic equation would not have any species because the spectator ions get canceled.

* Need ASAP * Explain the relationship between percent composition, Empirical formula, and molecular formula.
sweet-ann [11.9K]

By dividing the percentage composition with the molar mass of that element we will get the empirical formula. Then using that empirical formula and formula mass we can find the molecular formula.

<u>Explanation:</u>

The chemical properties of any substance are defined obviously by the different types and relative amounts of atoms constituting its primary entities (in case of covalent compounds the primary entities are molecules and ions in the event of ionic compounds).

A percent composition of any compound gives the mass percent of each element present in the compound; in addition to that frequently it is determined experimentally and utilized to derive an empirical formula of any compound. An empirical formula mass of any covalent compound could be comparable with the molar or molecular mass of a compound to acquire a molecular formula.

2. If you have 8.08 g of hydrogen, how many grams of ammonia will your produce?
Nikolay [14]

answer: Stoichiometry is a big word for a process that chemist’s use to calculate

amounts in reactions. It makes use of the coefficient ratio set up by balanced

reaction equations to make connections between the reactants and products

in reactions.

 Stoichiometry calculates the quantities of reactants and products in a

chemical reaction. The equation must be balanced!

 Questions that deal with amounts in reactions are examples of reaction

stoichiometry. We already have the tools necessary to solve this question.

We just need to learn a new way to apply skills such as writing chemical

formulas, calculating formula masses, and converting from mass to moles,

particles to moles, and volume of gases to moles.

 Mole to Mole Conversions- you must have the Mole Ratio.

Illustration:

Let’s use an analogy that we can understand to begin to understand the process.

The KEY to any mole conversion is the ratio of coefficients in the reaction

equation. Say I want to make a bacon double cheeseburger. Let’s get our recipe

together.

1 hamburger bun + 2 hamburger patties + 2 slices of cheese + 4 strips of bacon →

1 bacon double cheeseburger

Based on this recipe:

1) If I have five bacon double cheeseburgers:

a. How many hamburger buns did you use? → 5 hamburger bun

b. How many hamburger patties did you use? → 10 hamburger patties

c. How many slices of cheese did you use? → 10 slices of cheese

d. How many strips of bacon did you use? → 20 strips of bacon

2) How many bacon double cheeseburgers can you make if you start with:

a. 2 buns, 4 patties, 4 slices of cheese, 8 strips of bacon

2 bacon double cheese burgers

b. 1 dozen buns, 2 dozen patties, 2 dozen slices of cheese, 4 dozen strips of bacon

1 dozen bacon double cheese burgers
