Is NO a polar molecule?

2 answers:

4 0

Electronegativity values are useful in determining if a bond is to be classified as nonpolar covalent, polar covalent or ionic. The electronegativities of oxygen and nitrogen are respectively, 3.44 and 3.04 on Pauling scale, the electronegativity difference being, 0.4. The bond is considered to be non-polar covalent.

Non - polar molecules occurs when the election sharing during a convalent bond is equal, so there is no ionic charge and the electrons are disturbed symmetrically.

Answer:

If the volume of a gas increased from 2 to 6 L while the temperature was held constant, the pressure of the gas decreased by a factor of 3.

Explanation:

Boyle's law that says "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure." This means that if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

P * V = k

To obtain the proportionality factor k you must make the quotient:

$k=\frac{V2}{V1} =\frac{6 L}{2 L}$

k= 3

This means that if the volume of a gas increased from 2 to 6 L while the temperature was held constant, the pressure of the gas decreased by a factor of 3.

What is the percent by volume of isopropyl alcohol in a solution that contains 45 ml of isopropyl alcohol in 1.4 L of water?

Leya [2.2K]

Hey there!

There are 1000 mL in a liter.

1.4 L + 0.045 L = 1.445 L

In total there is 1.445 L of the solution.

To find the percent of isopropyl alcohol, divide the amount of isopropyl alcohol by the total amount.

0.045 ÷ 1.445 = 0.0311

Convert to a percent.

3.11%

Hope this helps!
