You found a sample of a solution that has a faint odor resembling vinegar (an acid). To verify that it is vinegar, you add a few

drops of phenolphthalein. The sample turns pink.
From this result, can you assume this sample is indeed vinegar or contains some vinegar?

What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?
Vikki [24]

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of N_{2} molecule is as follows.

Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

At 20 degrees Celsius the density of mercury is 13.6 g/cm cubed. What is the mass of 50.0 ml of mercury at 20 degrees Celsius?
Lynna [10]

Answer:

680g of mercury is the mass of the sample of mercury.

Explanation:

Density is an unit used to relates the mass of an object per unit of volume.

For example, in the problem, the density of mercury is 13.6g/cm³, as cm³ is equal to milliliters, mL, the density is: 13.6g/mL.

If you have 50.0mL of mercury, the mass is:

50.0mL * (13.6g / mL) =

<h3>680g of mercury is the mass of the sample of mercury.</h3>
