Example of Brønsted – Lowry acid-base:

HCl (aq) + H2O (l) → Cl− (aq) + H3O + (aq)

When viewed with the Brønsted-Lowry theory, in the ionization reaction of HCl when dissolved in water, HCl acts as an acid and H2O as a base. The HCl turns into a Cl− ion after giving a proton (H +) to H2O. H2O accepts protons by using a pair of free electrons in the O atom to bind to H + to form hydronium ions (H3O +).

Examples of Lewis Acid Bases:

H ++ NH3 → NH4 +

Ion H + (Proton) is a Lewis Acid because it can accept Electron Pairs, while NH3 is a Lewis Base.

<h2>Further Explanation </h2>

Acid is a compound that makes a sour taste. A base may be a compound that reacts with acids.

The Brønsted – Lowry acid-base theory

The Brønsted-Lowry Theory is an acid-base reaction theory proposed separately by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923. The basic concept of this theory is that when an acid and a base react with each other, acids will form their conjugate bases, and bases form their conjugate acids through proton exchange (hydrogen cations, or H +). This theory could be a generalization of the Arrhenius theory.

Lewis Acid-Base Theory

In 1923, G. N. Lewis proposed a broader acid-base theory compared to the two previous theories by emphasizing the electron pair associated with structure and bonding. According to the definition of Lewis acid-base:

acid is an electron pair acceptor.
bases are electron-pair donors.

There are many types of acid or bases. Based on the Bronsted-Lowry definition,

* A Bronsted-Lowry acid is a proton donor
* A Bronsted-Lowry base is a proton acceptor

Take this reaction for example:
HCl(aq)+ N<span>H</span>₃(aq)→N<span>H</span>⁴⁺(aq)+C<span>l</span>⁻(aq<span>)
</span>
HCl donates a proton, so it is a Bronsted-Lowry acid. Consequently, ammonia accepts this proton, so it is the Bronsted-Lowry base.

Tetraphosphorus Decaoxide has a molecular formula of P4O10, all else are known. Therefore the balanced chemical equation would be:

4PH3 + 8O2 --> 6H2O + P4O10

Taking into account the phases:

4PH3(g) + 8O2(g) --> 6H2O(g) + P4O10(s)

How much heat is required to raise the temperature of 670g of water from 25.7"C to 66,0°C? The specific heat

inna [77]

Answer:

Explanation:

q= mc theta

where,

Q = heat gained

m = mass of the substance = 670g

c = heat capacity of water= 4.1 J/g°C

theta =Change in temperature=( 66-25.7)

Now put all the given values in the above formula, we get the amount of heat needed.

q= mctheta

q=670*4.1*(66-25.7)

=670*4.1*40.3

=110704.1

Find the molarity of 186.55 g of sugar (C12H22O11) in 250. mL of water.

Anna [14]

Answer:

The molarity of this sugar solution in water is 2.18 M

Explanation:

Step 1: Data given

Mass of sugar (C12H22O11) = 186.55 grams

Molar mass of C12H22O11 = 342.3 g/mol

Volume of water = 250.0 mL = 0.250 L

Step 2: Calculate moles sugar

Moles sugar = mass sugar / molar mass sugar

Moles sugar = 186.55 grams / 342.3 g/mol

Moles sugar = 0.545 moles

Step 3: Calculate molarity of the sugar solution

Molarity = moles sugar / volume of water

Molarity = 0.545 moles / 0.250 L

Molarity = 2.18 MThe molarity of this sugar solution in water is 2.18 M

Which of the compounds above are strong enough acids to react almost completely with a hydroxide ion (pka of h2o = 15.74) or wit

luda_lava [24]

The compounds can react with OH⁻ and HCO₃⁻ only C₅H₆N pyridinium

<h3><em>Further explanation </em></h3>

In an acid-base reaction, it can be determined whether or not a reaction occurs by knowing the value of pKa or Ka from acid and conjugate acid (acid from the reaction)

Acids and bases according to Bronsted-Lowry

Acid = donor (donor) proton (H + ion)

Base = proton (receiver) acceptor (H + ion)

If the acid gives (H +), then the remaining acid is a conjugate base because it accepts protons. Conversely, if a base receives (H +), then the base formed can release protons and is called the conjugate acid from the original base.

From this, it can be seen whether the acid in the product can give its proton to a base (or acid which has a lower Ka value) so that the reaction can go to the right to produce the product.

The step that needs to be done is to know the pKa value of the two acids (one on the left side and one on the right side of the arrow), then just determine the value of the equilibrium constant

Can be formulated:

K acid-base reaction = Ka acid on the left : K acid on the right.

or:

pK = acid pKa on the left - pKa acid on the right

K = equilibrium constant for acid-base reactions

pK = -log K;

$K~=~10^{-pK}$
