List 3 scenarios for a substance being classified as a weak acid

Chemistry

A way to classify an acid as being weak is to determine how strongly the substance conducts electricity. If the acid or base conducts electricity strongly, it is a strong acid or base. If the acid or base conducts electricity weakly, it is a weak acid or base.

Answer:

3 scenarios:  

1. acetic acid, organic acid that comes from vinager

2. citric acid, that is present in some fruits

3. phosphoric acid , present in sodas

Explanation:

A weak acid is the one that partially transferres its proton (H+) to a water molecule ( partial dissociation), and usually a part of the original acid (HA) remains after the process of dissociation; that is why, a dissociation reaction of a weak acid is represented with an arrow of both ways.

HA ⇌ H^{+} +A^{-}

As we can see, the acetic acid, citric acid and phosphoric acid are great examples of weak acid. Their pH is higher thanks to its low dissociation, and they can even be eaten in low concentrations.

Identify the base-conjugate acid pair in this balanced equation:
Elan Coil [88]
<h3><u>Answer;</u></h3>

NH3/NH4+

<h3><u>Explanation;</u></h3>

From the equation;

NH3(aq)+HNO3(aq)→NH4+(aq)+NO3−(aq)  

NH3 is the base; while NH4+ is the conjugate acid  

HNO3 is the acid; while NO3- is the conjugate base  

  • The conjugate base of a Brønsted-Lowry acid is species that is formed after an acid donates a proton while the conjugate acid of a Brønsted-Lowry base is the species formed after a base accepts a proton.

2) Nitrogen gas will react with hydrogen gas to produce ammonia, NH3, How many
Delicious77 [7]

Answer:

12 grams of hydrogen gas

and 56 grams of nitrogen gas

The molar mass of ammonia is 17 g/mol.

68 grams of ammonia corresponds to  

17g/mol

68g

​

=4moles

4 moles of ammonia will be obtained from  

2

4×1

​

=2  moles of nitrogen and  

2

4×3

​

=6  moles of hydrogen.

The molar masses of nitrogen and hydrogen are 28 g/mol and 2 g/mol respectively.

2 moles of nitrogen corresponds to 2×28=56  grams.

6 moles of hydrogen corresponds to 6×2=12  grams.
