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 $Cl_2$ .

A car tire has a pressure of 2.38 atm at 15.2 c. If the pressure inside reached 4.08 atm, the tire will explode. How hot would t

stich3 [128]

The correct answer is 221.06 °C hot.

If P₁ is the pressure at T₁ and P₂ is the pressure at T₂ then,

P₁/T₁ = P₂/T₂

It is given that P₁ = 2.38 atm

T₁ = 15.2 degree C = 273 + 15.2 = 288.2 K

P₂ = 4.08 atm

T₂ = x

Thus, 2.38 / 288.2 = 4.08 / x

x = (4.08 × 288.2) / 2.38

x = 494.06 K

x = 494.06 - 273 °C = 221.06 °C

Therefore, the tire would get 221.06 °C hot.
