Answer:  (1.5 M) V1 = (3.40 M) (500mL)

            (multiply 3.40M x 500mL)    V1 = 1700 mL

1700 mL of the 1.5 M NaCl + 1200mL of water.

You have 1169.6 g of a bleach solution. The percent by mass of the solute sodium hypochlorite, NaOCl, is 3.62%. How many grams o
Aneli [31]

Answer:

Mass of solvent is 1127.3 g

Explanation:

NaOCl → 3.62%

This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:

100 g of bleach solution have 3.62 g

1169.6 g of bleach solution may have (1169.6  . 3.62) /100 = 42.3 g

42.3 g is the mass of NaOCl in the solution

Mass of solution = Mass of solvent + Mass of solute

1169.6 g = Mass of solvent + 42.3 g

1169.6 g - 42.3 g = Mass of solvent → 1127.3 g

Do you expect the O---O bond in H2O2 to be longer or shorter than the O---O bond in O2?
melomori [17]

Answer : The O-O bond in H_2O_2 will be longer than the O-O bond in O_2.

Explanation :

In the H_2O_2, the two oxygen atoms are bonded by the single bond and in O_2, the two oxygen atoms are bonded by the double bond.

As we know, the bond strength of double bond is greater than the single bond.

And the relation between the bond strength and bond length is,

\text{ Bond strength}\propto \frac{1}{\text{ Bond length}}

That means the higher the strength, the shorter will be the bond length.

Hence, the bond length of single bond will be longer than the double bond.

The structure of given molecule is shown below.
