The type of stereoisomerism that exist in the compound "Levocabastine" is an enantiomer (optical) isomerism.

<h3>What is stereoisomerism?</h3>

Stereoisomerism is also referred to as spatial isomerism and it can be defined as a form of isomerism in which chemical species of molecules have the same molecular formula but differ in how their atoms are positioned (arranged) in three-dimensional orientations of space.

This ultimately implies that, stereoisomerism occurs when two molecules comprises the same atoms that are connected in the same sequence but these atoms are positioned (arranged) differently in space.

<h3>The types of stereoisomerism.</h3>

In Chemistry, there are two (2) main types of stereoisomerism and these include:

Enantiomers (optical) isomerism.

Diastereomers (geometric) isomerism.

Based on scientific records, the type of stereoisomerism that exist in the compound "Levocabastine" is an enantiomer (optical) isomerism because its molecules are related to each other by a reflection and they are mirror images of one another but non-superimposable.

Suppose a current of 0.860A flows through a copper wire for 5.0 minutes. Calculate how many moles of electrons travel through th

denpristay [2]

Answer:

2.7×10⁻³ mole

Explanation:

Applying

Q = it.............. Equation 1

Where Q = amount of charge, i = current, t = time

From the question,

Given: i = 0.860 A, t = 5 minutes = (5×60) seconds = 300 seconds

Subsitute these values into equation 1

Q = (0.860×300)

Q = 258 C

If one mole of electron has a charge of 96500 C

Then, x mole of electron will have a charge of 258 C

1 mole ⇒ 96500 C

X moles ⇒ 258 C

Solve for X

X = (258×1)/96500

X = 2.7×10⁻³ mole

The fertilizer ammonium sulfate, (NH4)2SO4, is prepared by the reaction between ammonia (NH3) and sulfuric acid:

kumpel [21]

The mass of ammonia required to produce 2.40 × 10⁵ kg of (NH₄)₂SO₄ is 6.18 * 10⁴ Kg of ammonia.

<h3>What mass in kilograms of ammonia are required to produce 2.40 × 10⁵ kg of (NH₄)₂SO₄?</h3>

The mass of ammonia required to produce 2.40 × 10⁵ kg of (NH₄)₂SO₄ is determined from the mole ratio of the reaction.

The mole ratio of the reaction is obtained from the balanced equation of the reaction given below:

2NH₃(g) + H₂SO₄(aq) → (NH₄)₂SO₄(aq)

Mole ratio of NH₃ and (NH₄)₂SO₄ is 2: 1

Mass of 2 moles of ammonia = 2 * 17 = 34 g

Mass of 1 mole of (NH₄)₂SO₄ = 132 g

Mass of ammonia required = 34/132 * 2.40 × 10⁵ kg

Mass of ammonia required = 6.18 * 10⁴ Kg of ammonia.

In conclusion, the mole ratio is used to determine the mass of ammonia required.

A 150.0 mL sample of an aqueous solution at 25°C contains 15.2 mg of an unknown nonelectrolyte compound. If the solution has an

inysia [295]

<u>Answer:</u> The molar mass of the unknown compound is 223.2 g/mol

<u>Explanation:</u>

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

$\pi=iMRT$

where,

$\pi$ = osmotic pressure of the solution = 8.44 torr

i = Van't hoff factor = 1 (for non-electrolytes)

M = molarity of solute = ?

R = Gas constant = $62.3637\text{ L torr }mol^{-1}K^{-1}$

T = temperature of the solution = $25^oC=[273+25]=298K$

Putting values in above equation, we get:

$8.44torr=1\times M\times 62.3637\text{ L. torr }mol^{-1}K^{-1}\times 298K\\\\M=\frac{8.44}{1\times 62.3637\times 298}=4.54\times 10^{-4}M$

To calculate the molecular mass of solute, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Molarity of solution = $4.54\times 10^{-4}M$

Given mass of unknown compound = 15.2 mg = 0.0152 g (Conversion factor: 1 g = 1000 mg)

Volume of solution = 150.0 mL

Putting values in above equation, we get:

$4.54\times 10^{-4}M=\frac{0.0152\times 1000}{\text{Molar mass of unknown compound}\times 150.0}\\\\\text{Molar mass of unknown compound}=\frac{0.0152\times 1000}{150.0\times 4.54\times 10^{-4}}=223.2g/mol$

Hence, the molar mass of the unknown compound is 223.2 g/mol
