Which molecule contains a triple covalent
bond?
(1) H2 (3) O2
(2) N2 (4) Cl2

Answers

Answer: The correct answer is Option 2.

Explanation:

Covalent bond is defined as the b which is formed by the sharing of electrons between the atoms forming a bond.

Non-polar covalent bond is defined as the bond which is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc..

For the given options:

Option 1: $H_2$

Hydrogen is the 1st element of the periodic table having electronic configuration $1s^1$

This element needs 1 electron to attain stable electronic configuration and will form single covalent bond with another hydrogen atom.

Option 2: $N_2$

Nitrogen is the 7th element of the periodic table having electronic configuration $1s^22s^22p^3$

This element needs 3 electrons to attain stable electronic configuration and will form triple covalent bond with another nitrogen atom.

Option 3: $O_2$

Oxygen is the 8th element of the periodic table having electronic configuration $1s^22s^22p^4$

This element needs 2 electrons to attain stable electronic configuration and will form double covalent bond with another oxygen atom.

Option 4: $Cl_2$

Chlorine is the 17th element of the periodic table having electronic configuration $1s^22s^22p^63s^23p^5$

This element needs 1 electron to attain stable electronic configuration and will form single covalent bond with another chlorine atom.

Hence, the correct answer is Option 2.

N2 because it has 5 valence atoms so it needs 3 to have 8, wich is the octet rule, so three is a triple covalent bond

In a chemical change, the same atoms are recombined into a new substances,
True
Or False

Answers

True. In a chemical change, the same atoms are recombined into a new substances,

What happens in a chemical change

In a chemical change, also known as a chemical reaction, the atoms of the reactants are rearranged and recombined to form new substances with different chemical properties.

While the atoms themselves are not created or destroyed, their arrangement and bonding patterns change, resulting in the formation of new molecules or compounds. This process involves breaking and forming chemical bonds, leading to the creation of different substances with distinct properties from the original reactants.

What happens when Ca(NO3)2 and Na2CO3 combine?

Answers

When the two compounds are allowed to be in contact and reacts the product would be sodium nitrate (NaNO3) and calcium carbonate (CaCO3). This reaction is a double displacement reaction. The balanced equation is :

Ca(NO3)2 + Na2CO3 = 2NaNO3 + CaCO3

Water, H2O, frequently forms Hydrogen Bonds with other non metal atoms. Why does water do this? A: the Oxygen has a partial negative charge which attracts atoms and molecules that have a position or partial positive charge B: The Hydrogen has a partial negative charge which attracts atoms and molecules that have a positive or partial positive charge C: Because Oxygen is extremely electronegative it attracts atoms and molecules with a negative or partial negative charge D: Because Hydrogen has a very low electronegative rating it attracts atoms and molecules with a positive or partial positive charge
