what mass of hbr is dissolved in 500 ml water of hcl solution if 25 ml of this solution is neutralized by 20ml water of 0.67 M NaOH

Answers

Answer 1

The mass of HCl dissolved in 500 ml water of HCl solution is equal to 9.78 g.

What is a neutralization reaction?

A neutralization reaction can be defined as a reaction in which an acid and base react to produce salt and water.

When HCl reacts with NaOH, the resulting salt is sodium chloride and water.

HCl    +    NaOH   →   NaCl   + H₂O

Given, the volume of NaOH solution = 20 ml

The concentration of NaOH = 0.67 M

The number of moles of NaOH = (20 /1000) ×0.67 = 0.0134

The number of moles of HCl = 0.0134 mol

The volume of HCl taken = 25 ml = 0.025 L

The concentration of HCl solution = 0.0134/0.025 = 0.536 M

The volume of HCl solution = 500 ml

The number of moles of HCl = 0.536 × 0.5 = 0.268 mol

The mass of HCl = 0.268 × 36.5 = 9.78 g

Which type of isomers are o-xylene, m-xylene, and p-xylene?

structural isomers
optical isomers
geometric isomers

Answers

o-xylene, m-xylene, and p-xylene are structural isomers.

o-xylene, m-xylene, and p-xylene are examples of aromatic isomers, also known as ortho-, meta-, and para-xylene, respectively. These isomers are classified as aromatic because they are part of a family of compounds known as aromatic hydrocarbons, which contain a ring of six carbon atoms bonded to each other in a specific way.

o-xylene, m-xylene, and p-xylene are also examples of structural isomers. Structural isomers are compounds that have the same molecular formula but differ in the arrangement of their atoms. In the case of o-xylene, m-xylene, and p-xylene, the atoms are arranged differently around the ring of six carbon atoms.

o-xylene, m-xylene, and p-xylene are not optical isomers, which are also known as enantiomers. Optical isomers are compounds that are mirror images of each other but are not superimposable. Optical isomers are important in medicinal chemistry because they can have different biological properties even though they have the same molecular formula and structure.

o-xylene, m-xylene, and p-xylene are also not geometric isomers. Geometric isomers are compounds that have the same molecular formula and the same arrangement of atoms, but differ in the orientation of their atoms or groups of atoms in space. Geometric isomers are often found in compounds with cis-trans double bonds or ring structures.

what has very good electrical conductivity

Answers

Many metals have very good electrical conductivity. This is because metals have a large number of free electrons in their outermost energy levels, which are able to move freely through the metal's structure. This allows metals to easily conduct electric current.

Some examples of metals with very good electrical conductivity include copper, silver, and gold. These metals are often used in electrical wiring and other applications where good conductivity is important.

In addition to metals, other materials can also have very good electrical conductivity. For example, some electrolytes, such as certain solutions of salts, can conduct electricity very well. This is because electrolytes contain ions that are able to move freely through the solution, allowing electric current to flow.

Overall, materials with good electrical conductivity have a high number of free electrons or ions that are able to move freely through the material, allowing electric current to flow easily.

the enthalpy of sublimation for a particular compound at 25.0 c is 32.4 kj/mol. the enthalpy of fusion for this compound at its melting point is 10.4 kj/mol. calculate the enthalpy of vaporization for this compound.

Answers

The enthalpy of vaporization for this compound is 22.0 kJ/mol.

What is vaporization?

Vaporization is a process in which a liquid or solid is transformed into a gaseous state. It occurs when molecules in the liquid or solid absorb enough energy to break their intermolecular bonds and become a gas. This process can be carried out either through the application of heat or pressure, or through a process known as sublimation, which occurs when a solid is exposed to a vacuum.

ΔHₙ = ΔHₓ - ΔHₐ

Where, ΔHₙ = Enthalpy of vaporization

ΔHₓ = Enthalpy of sublimation (32.4 kj/mol)

ΔHₐ = Enthalpy of fusion (10.4 kj/mol)

ΔHₙ = 32.4 - 10.4

ΔHₙ = 22.0 kJ/mol

The enthalpy of vaporization for this compound is the difference between the enthalpy of sublimation and the enthalpy of fusion. Therefore, the enthalpy of vaporization for this compound is 22.0 kJ/mol.

Ore veins and disseminated deposits are  differ in terms of their size, shape, and distribution.

An ore vein is a large, continuous body of mineral deposits that are typically found in fractures or voids in rock formations. Ore veins are typically formed when minerals that are dissolved in water fill a void or crack in a rock formation. Ore veins are typically quite large and can be several meters in width and several kilometers in length. They are also typically found at depths of several hundred meters or more. Ore veins are generally easier to mine because they are more concentrated and can be more easily accessed through underground mining methods.

A disseminated deposit, on the other hand, is a type of mineral deposit that is dispersed or scattered throughout a larger rock formation.

Longitudinal sound waves exhibit alternating pressure deviations leading to compression and rarefaction, while transverse waves exhibit alternating shear stress perpendicular to the propagation path.

Waves can cause matter to move up and down but can not carry along with them. As the temperature of the air increases the molecules start to vibrate faster eventually the speed of the sound increase.

If one form of a gene can mask the appearance of another form, that form is considered dominant over the other form. Option B.

What are dominant alleles?

According to Mendel, genes are usually made up of 2 alleles. These alleles can be the same or different. When the alleles are the same, the gene is said to be homozygous. If the alleles are different, the gene is said to be heterozygous.

When the two alleles that make up a gene are different, one will be dominant and the other will be recessive. The dominant gene masks the effect of the recessive gene. In other words, the recessive gene cannot be expressed as long as it coexists with the dominant gene. In order for it to be expressed, it has to be in two copies or a homozygous recessive form.

For the dominant allele, however, only one copy is needed for it to be expressed.

In summary, if one form of a gene can mask the appearance of another form, that form is considered dominant over the other form.

A kangaroo was 396 meters east of a lake. In 12 seconds, the kangaroo hopped one-third of the way to the lake at a constant velocity. What was the kangaroo's velocity?

Answers

The velocity of an  object is the ratio of the distance to the time. The distance travelled by Kangaroo is 396 m in 12 seconds. So its velocity is 33 m/s.

What is velocity?

Velocity is a physical quantity and it is the measure of distance travelled per unit time. Velocity is the rate of speed and it  is a vector quantity.The velocity can be expressed in terms of m/s, Km/hr etc.

Mathematically, velocity is the ratio of distance to the time.

Given that, distance covered by kangaroo is 396 meters.

time taken = 12 s.

therefore, velocity can be calculated as follows:

velocity = distance/time

g two nuclei of 40ca (atomic number 20) undergo fusion to form a nucleus of 80 zr (atomic number 40). the total binding energy of 40ca is b. what would be the best estimate for the total binding energy of 80 zr?

Answers

The total binding energy of 80Zr is therefore approximately 4.58MeV.

What is isotopes?

An isotope is an atom of a particular element that has a different number of neutrons than other atoms of that same element. This difference in the number of neutrons causes the isotopes to have different atomic masses. Isotopes of an element can be either stable or unstable. Stable isotopes are not radioactive and do not decay, while unstable isotopes are radioactive and undergo radioactive decay.

The total binding energy of 80Zr can be estimated using the mass defect of the two isotopes. According to the semi-empirical mass formula, the binding energy of a nucleus is related to its mass defect. The mass defect of the two nuclei can be calculated by subtracting the mass of the separate nuclei from the mass of the combined nucleus.

The mass of 40Ca is 39.96259 amu and the mass of 80Zr is 79.91652 amu. The combined mass of the two nuclei is 119.87911 amu.
The mass defect of the combined nucleus is therefore 119.87911 - 39.96259 - 79.91652 = 0.005 amu,

Collision frequency is defined as the collision of atoms on increasing pressure atoms start moving from one place to another. The relationship pressure is linear with solubility.
