Hydrogen fluoride reacts with ammonia in an acid-base reaction:

Chemistry
1 answer:
Karolina [17]3 years ago
7 0

Answer: a)  HF(aq)+NH_3(aq)\rightarrow NH_4^+(aq)+F^-(aq)

b) NH_4^+: conjugate acid of NH_3

F^- : conjugate base of HF

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

For the given reaction:

HF(aq)+NH_3(aq)\rightarrow NH_4^+(aq)+F^-(aq)

Here HF is loosing a proton, thus it is considered as an acid and after losing a proton, it forms F^- which is a conjugate base.

Similarly ,NH_3 is gaining a proton, thus it is considered as an base and after gaining a proton, it forms NH_4^+ which is a conjugate acid.

Three beakers contain clear, colorless liquids. one beaker contains pure water, another contains salt water, and another contain
tiny-mole [99]
First, we'll identify the beaker containing pure water as follows:
We'll take equal masses from each of the three beakers and measure the mass of each.
We'll then identify the density of each by using the rule : density =mass/volume
Pure water will be the liquid having density equal to 1 gm/cm^3

Then, we'll differentiate between the salt and sugar solution by measuring the conductivity of each solution. Salt solution is a good conductor while solution of sugar is a bad conductor.

Explain why the molar ratio is needed to determine the theoretical mass ratios.
choli [55]

Answer:

The overview of the subject is outlined underneath in the summary tab.

Explanation:

  • The molar ratio seems to be essentially a balanced chemical equilibrium coefficient that implies or serves as a conversion factor for the product-related reactants.
  • This ratio just says the reactant proportion which reacts, but not the exact quantity of the reacting product. Consequently, the molar ratio should only be used to provide theoretical instead of just a definite mass ratio.

Which compound can be used to preserve biological specimens? A central C is double bonded to an O, and single bonded to 2 H. A c
Darina [25.2K]

Answer:

A central C is double bonded to an O, and single bonded to 2 H

Explanation:

Methanal, also known as formaldehyde, is a chemical compound used to preserve dead biological specimens for further study. It is called formalin when in a solution and it helps keep specimens in a fresh state by hardening the tissues of the specimen involved.

Formaldehyde is a gaseous compound that has an aldehyde functional group i.e. -CHO and has a chemical formula, H-CHO or CH2O as described in the question that a central C is double bonded to an O, and single bonded to 2 H (see attached image for structural formula).
