Answer:
You can get 7 answers wrong.
Explanation:
Let's calculate the average
So if you correctly answer 8 -15 (7.5 is approximated to 8 )questions correctly you will pass.
So you can get 7 answers wrong.
Answer:
The answer to your question is: letter B.
Explanation:
Carbon atom double-bonded to an oxygen atom C= O,
a) Carbohydrate group this group does not exist
b)Carbonyl group This option is right, carbonyl group is C=O
c) Hydroxyl group This option is incorrect, hydroxyl group is OH, very different from C=O
d) Ketone group Ketone group does not exist, ketones have the same functional group as aldehydes (C=O)

The emission wavelength of the atoms excited above the ground state is 599.8 nm.
<h3>Emission wavelength of the atoms</h3>
The emission wavelength of the atom is determined by using the following formulas as shown below;
E = hf
E = hc/λ
where;
- E is the energy of the atom
- h is Planck's constant
- c is speed of light
- λ is the emission wavelength
λ = hc/E
λ = (6.626 x 10⁻³⁴ x 3 x 10⁸) / (3.314 x 10⁻¹⁹)
λ = 5.998 x 10⁻⁷ m
λ = 599.8 x 10⁻⁹ m
λ = 599.8 nm
Thus, the emission wavelength of the atoms is 599.8 nm.
