According to Avogadro's number, there are 6.926×10²⁴ representative particles in 11.5 moles of silver.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number or number of moles×Avogadro's number=11.5×6.023×10²³=6.926×10²⁴ atoms.

Thus, there are 6.926×10²⁴ representative particles in 11.5 moles of silver.

The question is incomplete, the complete question is:

At a certain temperature, the equilibrium constant [tex]K_{eq}[/tex] for the following reaction is 0.74:

[tex]NO_3(g)+NO(g)\rightleftharpoons 2NO_2(g)[/tex]

Suppose a 49.0 L reaction vessel is filled with 1.5 mol of [tex]NO_3[/tex] and 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium?  

A. There will be very little [tex]NO_3[/tex] and NO.

B. There will be very little [tex]NO_2[/tex]

C. Neither of the above is true.

Answer: The correct option is B. there will be very little [tex]NO_2[/tex]

Explanation:

We are given:

Initial moles of [tex]NO_3[/tex] = 1.5 moles

Initial moles of NO = 1.5 moles

Volume of vessel = 49 L

As, moles of reactants and moles of products are equal, the volume term will not appear in the equilibrium constant expression.

Equilibrium constant for the reaction = 0.74

For the given chemical equation:

                                  [tex]NO_3(g)+NO(g)\rightleftharpoons 2NO_2(g)[/tex]

Initial:                            1.5           1.5             -

At eqllm:                     1.5-x        1.5-x            2x

The expression of equilibrium constant for the above reaction:

[tex]K_{eq}=\frac{[NO_2]^2}{[NO_3]\times [NO]}[/tex]

Putting values in above equation, we get:

[tex]0.74=\frac{(2x)^2}{(1.5-x)(1.5-x)}\\\\x=-1.13, 0.451[/tex]

Neglecting the negative value of equilibrium constant because concentration cannot be negative

Equilibrium concentration of [tex]NO_3[/tex] = (1.5 - x) = (1.5 - 0.451) = 1.049 moles

Equilibrium concentration of NO = (1.5 - x) = (1.5 - 0.451) = 1.049 moles

Equilibrium concentration of [tex]NO_2[/tex] = 2x = [tex](2\times 0.451)=0.902mol[/tex]

There are 3 possibilities:

Here, the value of [tex]K_{eq}=0.74[/tex], which is less than 1, therefore the reaction is reactant favored and we can say that there will be very little [tex]NO_2[/tex].

Hence, the correct option is B. there will be very little [tex]NO_2[/tex]

Answer:

The conjugate acid

Solution

Bronsted-Lowry

Acid ⇒ H⁺ + conjugate base

Bases + H⁺⇒ conjugate acids

Acid and conjugate base : H₂S and HS−

Base and conjugate acid : HCO₃− and H₂CO₃

H₂S gives (H⁺), then the remaining acid is a conjugate base  HS−

HCO₃− receives (H +), then the conjugate acid H₂CO₃

Explanation:

The compound ammonium phosphate is a strong electrolyte. - This means that ammonium phosphate fully ionizes - dissociates to positive and negative ions completely.

The ions formed when ammonium phosphate dissociates are; Ammonium ion NH₄⁺ and sulphate ion SO₄⁻²

The transformation is given in the equation;

(NH₄)₂SO₄ --->  NH₄⁺ + SO₄⁻²

Upon balancing;

(NH₄)₂SO₄(s) --->  2NH₄⁺(aq) + SO₄⁻²(aq)

Answer:

C

Explanation:

We know that the molar mass of KOH is 56 gmol-1

Molar mass of Mg(OH)2 is 58.31 g/mol

Now; the balanced reaction equation is; MgCl2 + 2KOH → Mg(OH)2 + 2KCI

Hence;

2 moles of KOH yields 1 mole of Mg(OH)2

4 moles of KOH yields;

4 moles of KOH/1 mol * 1   mole Mg(OH)2 /2 moles KOH * 58.31 g Mg(OH)2 / 1 mole Mg(OH)2

So option c is correct

Answer:

4mol MG(OH)2/1 * 2mol KOH/1 mol MG(OH2) * 56.10g KOH/1 mol KOH

The balance chemical equation is 2LiOH + CO2 → Li2CO3 + H2O. Therefore, option A is correct.

A chemical equation is said to be balanced if the quantity of each type of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the change are both equal.

The law of conservation of mass states that when a chemical reaction takes place, the mass of the reactants and products should be equal. As a result, during the chemical process, the number of atoms in each element remains constant. The chemical equation must be balanced as a result.

The chemical equation is said to be balanced if there are no inequalities. Every element in this illustration now has the same amount of atoms on the reactant and product sides.

Thus, option A is correct.

Answer:

C. 96,657 Pa, 966 millibar, 725 Torr

Explanation:

The pressure of 725 mmHg in Pa, millibars, and Torr is 96,657 Pa, 966 millibar, 725 Torr. Hence option C is correct.

Pressure is defined as the force that is applied perpendicularly to an object's surface in relation to the area that it is dispersed over. Pressure can actually be a very good thing. Stress only occurs and has a fully negative impact when it continues to grow and that sensation of serenity and order is replaced with one of being out of control.

Given pressure = 725 mmHg

1 mmHg = 133.32 Pa

725 mmHg = 133.32 x 725 Pa

                  = 96,657 Pa

1 mmHg = 1.333 millibar

725 mmHg = 725 x 1.333 millibar

                   = 966 millibar

1 mmHg = 1 torr

725 mmHg = 725 Torr

Thus, the pressure of 725 mmHg in Pa, millibars, and Torr is 96,657 Pa, 966 millibar, 725 Torr. Hence option C is correct.

Explanation:

A is a Metallic Solid

Let us look again at the physical properties of metals;

Metals are

We can now see that both ductility and electrical conductivity are metallic properties.

B is a Molecular solid

Molecules are formed when atoms share electrons. In molecules, there are no free electrons hence molecules do not conduct electricity.

Secondly, molecules are held together in the solid state by weak dispersion forces hence molecular solids have a low melting point.
