Answer:
A. Atoms gain, lose, or share electrons to achieve a full valence shell
Explanation:
The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.
In this process bonds are formed when there is an attraction between the two substances. For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation. Covalent compounds, form by sharing of electrons.Therefore, the octet rule is attained when atoms gain full valence configuration.

Li and S - covalent or ionic bond?
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.
A candy bar has ____ energy.
A. Kinetic
B. Potential
Answer:
Potential energy
Explanation:
A candy bar has carbs, sugars, and calories which are potentially going to be used as energy in a body.

Explanation:
Because the candy bar is sitting still.
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
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

Answer:
1235
Explanation:
if thers a a guess in that number
The compound V₂O₅ has a Seebeck coefficient at a temperature of 50 °C of -990 μV/K.
What is a compound?Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds .Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

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
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.

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