Li and S - covalent or ionic bond?

Answers

Answer:

It is an ionic bond.

Explanation:

Ionic bonds occur when a metal and a nonmetal combine, while covalent bonds occur between two nonmetals. Lithium is a metal and sulfur is a nonmetal.

What is the enthaply of dissolution? ​

Answers

Answer:

The enthalpy change of solution refers to the amount of heat that is released or absorbed during the dissolving process (at constant pressure).

Explanation:

The enthalpy of solution, enthalpy of dissolution, or heat of solution is the enthalpy change associated with the dissolution of a substance in a solvent at constant pressure resulting in infinite dilution.
The enthalpy of solution is most often expressed in kJ/mol at constant temperature. The energy change can be regarded as being made of three parts, the endothermic breaking of bonds within the solute and within the solvent, and the formation of attractions between the solute and the solvent. An ideal solution has a null enthalpy of mixing. For a non-ideal solution it is an excess molar quantity.

Explanation:

A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity

Answers

Answer:

The final velocity of the motorcycle is 64.7 m/s

Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation

Explanation:

Using the equation of motion that contains all the given values in the question: v² = u² + 2as

where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance

v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m

v² = 0² + 2 * 4.55 * 460

v² = 4186

take square root of both sides

v = 64.7 m/s

Therefore, the final velocity of the motorcycle is 64.7 m/s

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane​

Answers

Answer:

C. the carbons in ethene are linked by double bonds

Explanation:

The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.

In single bonds afforded with the ethane compound, there is free rotation.

The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

Type of Solution
Explanations about the differences of
the two solutions
Saturated solution
Unsaturated solution​

Answers

Answer:

See explanation

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

A bad case of tonsillitis can sometimes affect a person’s breathing.How is this possible ?

Answers

Answer:

Tonsillitis is inflammation of tonsils. It is caused by viral infection and very rarely by bacterial infection.

It is a very serious problem in case of children, adults and teenagers. The continuous coughing can lead to swelling in the throat which in case affects the  passage of airways.

This hindered air passage can cause breathing problems. The inflammation can also affect the passage of air and affects breathing.

Conglomerate is closely related to sandstone and displays many of the same types of sedimentary structures. Sandstone is a notably popular building material, used for things like flagstones and tile.

Conglomerate rocks are colorful and attractive; however, it is rarely used as ornamental stone for interior use because of its unreliable physical strength and durability.

Conglomerate has very few commercial uses, though it can be crushed to make a fine aggregate that can be used when a low-performance material is needed.

Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. Because of the large size of the clasts, it takes a very strong water current to transport and shape the rocks. As they tumble through the running water or moving waves, they form their rounded shape.

These rocks can be found in sedimentary rock sequences of all ages. They probably make up less than one percent by weight of all sedimentary rocks.
