<u>Answer:</u> The correct answer is electron pairs and electrons.

<u>Explanation:</u>

Covalent bond is defined as the bond which is formed by the sharing of electrons between two atoms that are forming a compound.

A bond is formed when two electrons are shared between the atoms. In covalent bond, the atoms are held together by the attraction of electron pairs that are present between them.

Covalent bond can be single, double or triple bond. A single bond is formed when 2 electrons (1 electron pair) are present between the atoms.

A double bond is formed when 4 electrons (2 electron pairs) are present between the atoms.

A triple bond is formed when 6 electrons (3 electron pairs) are present between the atoms.

Hence, the correct answer is electron pairs and electrons.

1. How many molecules of S2 gas are in 756.2 L?
AfilCa [17]

Answer: There are 2.032 \times 10^{25} molecules S_{2} gas are in 756.2 L.

Explanation:

It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of  moles present in 756.2 L are calculated as follows.

Mole = \frac{Volume}{22.4 L}\\= \frac{756.2 L}{22.4 L}\\= 33.76 mol

According to mole concept, 1 mole of every substance contains 6.022 \times 10^{23} molecules.

Therefore, molecules of S present in 33.76 moles are calculated as follows.

1 mol = 6.022 \times 10^{23}\\33.76 mol = 33.76 \times 6.022 \times 10^{23}\\= 2.032 \times 10^{25}

Thus, we can conclude that there are 2.032 \times 10^{25} molecules S_{2} gas are in 756.2 L.
