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.

Chemical equations are balanced by changing the subscripts of the molecules.
AnnZ [28]
The correct answer is false. <span>Chemical equations are balanced not by changing the subscripts of the molecules instead by changing the coefficients of each molecule. However, the subscripts are helpful in balancing equations because they are used in counting the number of atoms or molecules.</span>

What is the pH of an acetic acid solution where the concentration of acetic acid is 2 mM and the concentration of sodium acetate
schepotkina [342]

Answer:

pH = 5.76

Explanation:

We can solve this problem by using<em> Henderson-Hasselbach's equation</em>:

pH = pKa + log\frac{[SodiumAcetate]}{[AceticAcid]}

We are already know all the required information, thus we<u> input the data given by the problem</u>:

pH = 4.76 + log(20/2)

And finally <u>calculate the pH</u>:

pH = 5.76

The pH of that acetic acid solution is 5.76.
