Answer: The correct answer is Solar eclipse.

Explanation:

From the given options:

Neap tides occurs when Sun and Moon form right angles with Earth. The total gravitational pull is weakened, because it acts from two different directions. These tides occur twice a month.

Spring tides occur when Sun, Moon and Earth, all align in the same line. The gravitational pull of Sun and Moon, both combine and contribute to the occurrence of these tides. These tides occur twice each lunar month.

A lunar eclipse happens when Moon passes directly behind the Earth and into its shadow. This occurs when Earth lies between Sun and Moon, due to which no light reached Moon and it gets eclipsed.

A solar eclipse happens when Moon comes in between Sun and the Earth and it blocks the Sun rays falling on the Earth.

Hence, the correct answer is Solar eclipse.

What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?

Vikki [24]

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of $N_{2}$ molecule is as follows.

$Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0$ As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

What is the difference between ionic and covalent bonds? Give an example of a each type

Norma-Jean [14]

Answer:

Ionic bonds are opposite, whereas Covalent bonds are opposite.

Explanation:

Two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and othercovalent bonds.

Examples:

Sodium Chloride and Sodium Fluoride are examples of Ionic bonds.

and

Water and Carbon Dioxide are examples of Covalent bonds.
