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.

Assuming the same temperature and pressure for each gas, how many milliliters of carbon dioxide are produced from 16 0 mL of CO
aivan3 [116]

Answer:

V_{CO_2}=16.0mL

Explanation:

Hello,

In this case, given that the same temperature and pressure is given for all the gases, we can notice that 16.0 mL are related with two moles of carbon monoxide by means of the Avogadro's law which allows us to understand the volume-moles relationship as a directly proportional relationship. In such a way, since in the chemical reaction:

2CO(g)+O_2(g)\rightarrow 2CO_2(g)

We notice two moles of carbon monoxide yield two moles of carbon dioxide, therefore we have the relationship:

n_{CO}V_{CO}=n_{CO_2}V_{CO_2}

Thus, solving for the yielded volume of carbon dioxide we obtain:

V_{CO_2}=\frac{n_{CO}V_{CO}}{n_{CO_2}} =\frac{2mol*16.0mL}{2mol}\\ \\V_{CO_2}=16.0mL

Best regards.
