Answer:

A bent molecule with the same length of chemical bonds

Explanation:

Ozone has three 3 oxygen atoms and its molecular formula of ozone is O_3.

The central oxygen atom is sp2 hybridized and has one lone pair. Because sp2 hybridization and lone pair, shape is bend. Resonance occur in ozone because lone pair and double bond are in conjugation, therefore, ozone can be represented as a resonance hybrid with same bond lengths.

Therefore, option 2 is correct.

A bent molecule with the same length of chemical bonds

A laser emits a green light with wavelength of 515 nm. Calculate the frequency of this light.
pentagon [3]

Answer:

Frequency=5.83\times 10^{14}\ Hz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 515 nm

Also, 1 m = 10^{-9} nm

So,  

Wavelength = 515\times 10^{-9} m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{515\times 10^{-9}}\ Hz

Frequency=5.83\times 10^{14}\ Hz

How do you do these?
Agata [3.3K]

Solve these problems like weighted averages:

The first one:

Multiply the masses (isotope numbers) by the decimal form of the percentage. Add them

0.076 (6) + 0.924 (7) = 6.924


The second one:

0.2 (10) + 0.8 (11) = 10.8


If you think about it, these answers make sense. 6.924 is much closer to 7 than to 6 (since there's a lot more lithium-7 than there is lithium-6). 10.8 is closer to 11 than to 10.

224 x 10' is incorrect scientific notation, how should this be written in correct scientific notation?
riadik2000 [5.3K]

Answer:

2.24 x 10^3

Explanation:

When writing in scientific notation, you need to simplify the subject till there's only one digit on the left of the decimal point, so in this problem you had to move the decimal point over two more places.

It has already been moved once, shown by the 10^1, so you add 2 to the 10^1 to get 10^3.
