Which substance has a nonpolar covalent bonds? Cl2 SO3 SiO2 CCl4

Nikolay [14]

Answer:

Substance with a nonpolar covalent bonds is $Cl_2$ .

Explanation:

Polar covalent compound: This compound is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: $CO_2,NO_2$ etc..

Non-polar covalent compound: This compound 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.

Substance with a nonpolar covalent bonds is $Cl_2$ .

The molar mass of nitrogen (N2) is 28.02 g/mol. What is the mass, in grams, of 4.60 mol of N2?0.1646.0923.4129

kati45 [8]

Answer is 128.892 g.

moles (mol) = mass (g) / molar mass (g/mol)

According to the given data,
moles = 4.60 mol
mass = ?
molar mass = 28.02 g/mol

By substitution,
4.60 mol = mass / (28.02 g/mol)
mass = 4.60 mol x 28.02 g/mol
mass = 128.892 g

Hence, mass of 4.60 mol of N₂ is 128.892 g.
