The reaction of a Lewis acid with a Lewis base would most likely be accompanied by an increase in which item?covalent bonds

hydronium ions

electron pairs

hydroxide ions

Answers

Answer 1

Answer:

The correct option is COVALENT BONDS.

A Lewis acid is defined as a substance which accept a pair of electron while a Lewis base refers to a substance that donate an unshared pair of electrons to another chemical specie with which it shared the donated pair of electrons.

Lewis acid and Lewis base react together to form salt and water. This type of reaction is called neutralization reaction. The neutralization reaction of Lewis acid and Lewis base involves electron pairs transfer, thus, there is an increase in the number of covalent bonds during this reaction.

Answer 2

Answer:

Answer:

The correct answer is "covalent bonds".

Explanation:

A covalent coordinated or dative bond is formed when two atoms are linked together, sharing a pair of electrons. But only one of these atoms is the one that brings the pair of shared electrons. For this type of bond to occur, it is required that the donor atom has a pair of free electrons in an outer orbital and the acceptor atom has the capacity to receive that pair of electrons in its last valence layer.

On the other hand, a Lewis base is a substance that can share or donate a pair of electrons, because they have a pair of solitary electrons. A Lewis acid is that substance that accepts or takes a pair of electrons because they have their last electron layer incomplete.

It is then possible to say that an Lewis acid-base reaction is formed by the Lewis acid and base joined by a coordinated covalent bond.

So, the correct answer is "covalent bonds".

What volume of a 5.0% (v/v) Acetic Acid solution will contain 40.mL of Acetic Acid?

Answers

5.0% ( V/V) :

5.0 mL ------------- 100 mL ( solution )
40 mL --------------- ? ( solution )

V = 40 . 100 / 5.0

V = 4000 / 5.0

V = 800 mL

Calculate the molecular weight of a dibasic acid.0.56gm of which is required 250ml of N/20 sodium hydroxide solution for neutralization.

Answers

Answer: The molecular weight of the dibasic acid is 89.6 g/mol

Explanation:

Normality is defined as the amount of solute expressed in the number of gram equivalents present per liter of solution. The units of normality are eq/L. The formula used to calculate normality:

$\text{Normality}=\frac{\text{Given mass of solute}* 1000}{\text{Equivalent mass of solute}* \text{Volume of solution (mL)}}$ ....(1)

We are given:

Normality of solution = $(1)/(20)=0.05N$

Given mass of solute = 0.56 g

Volume of solution = 250 mL

Putting values in equation 1, we get:

$0.05=\frac{0.56* 1000}{\text{Equivalent mass of solute}* 250}\n\n\text{Equivalent mass of solute}=(0.56* 1000)/(0.05* 250)=44.8g/eq$

Equivalent weight of an acid is calculated by using the equation:

$\text{Equivalent weight}=\frac{\text{Molar mass}}{\text{Basicity}}$ .....(2)

Equivalent weight of acid = 44.8 g/eq

Basicity of an acid = 2 eq/mol

Putting values in equation 2, we get:

$44.8g/eq=\frac{\text{Molar mass}}{2eq/mol}\n\n\text{Molar mass}=(44.8g/eq* 2eq/mol)=89.6g/mol$

Hence, the molecular weight of the dibasic acid is 89.6 g/mol

The molar mass of I2 is 253.80 g/mol, and the molar mass of NI3 is 394.71 g/mol. How many moles of I2 will form 3.58 g of NI3?

Answers

The balanced chemical reaction is:

N2 +3 I2 = 2NI3

We are given the amount of product formed. This will be the starting point of our calculations.

3.58 g NI3 ( 1 mol NI3 / 394.71 g NI3 ) ( 3 mol I2 / 2 mol NI3 ) = 0.014 mol I2.

Thus, 0.014 mol of I2 is needed to form the given amount of NI3.

Answer:

Answer is 0.0136.

Explanation:

The major argument of opponents of the 1919Treaty of Versailles was that the treaty would
require the United States to
(1) become involved in future international
conflicts
(2) pay for war damages
(3) adopt a policy of military alliances
(4) keep troops permanently in Europe

Answers

The Treaty of Versailles would require the United States to become involved in future international conflicts.

The Treaty of Versailles was signed to end World War I in 1919.
The treaty also became a peace treaty presented by the Allied (France, Britain and the United States).
The opponents of the Treaty of Versailles, like, Germany oppose America involvement in Europe.
They believed that America, being disconnected geographically by the ocean, has no right to interfere.
When the United States had entered the war, the Germans protested.

Therefore we can conclude that Germans oppose America involvement in future international conflicts.

Thus option 1. is the correct answer.

What is the van't hoff factor of C7H7NO?

Answers

Answer:

i = 1

Explanation:

Van't Hoff factor (i) is explained as the number of ions dissolved in solution.

It is needed to determine colligative properties which depend on the amount of solute.

C₇H₇NO is an organic compound → benzamide

All the organic compound have 1, as Van't Hoff factor.

In order to predict i, you consider ionic salts. For example:

AlCl₃

CaCl₂

NH₄NO₃

When you dissociate them, you determine i:

AlCl₃ → Al³⁺ + 3Cl⁻ i =4

CaCl₂ → Ca²⁺ + 2Cl⁻ i = 3

NH₄NO₃ → NH₄⁺ + NO₃⁻ i =2

Who wrote the banned book that Giordano Bruno read that gave him the idea that the Universe was infinite?

Answers

The person who wrote the banned book that Giordano Bruno read that gave him the idea about the universe was infinite is Steven Soter.

The book that influenced Giordano Bruno's idea of an infinite universe was 'De revolutionibus orbium coelestium' by Nicolaus Copernicus. It opposed the geocentric model, leading to Bruno's emphasis on the infinite universe theory. Though banned, the book wielded substantial impact.

The book that Giordano Bruno read, which gave him the idea that the Universe was infinite, was 'De revolutionibus orbium coelestium' ('On the Revolutions of the Heavenly Spheres') written by Nicolaus Copernicus. Belonging to the heliocentric theory, the book challenged the geocentric model in which Earth was at the universe's core. Bruno emphasized the argument of an infinite universe presented in the text, which ultimately got him into trouble with the Inquisition. Despite being banned, its impact on Bruno and scientific thought was significant.
