EleoNora [17]3 years ago
6 0

Answer: 37 protons, 48 neutrons, and 36 electrons.

Explanation: I assume "Revision" is Rubidium. It is atomic number 37, so it has 37 protons. It's atomic mass is 85, so it has an average of (85-37) = 48 neutrons. It has a charge of +1, so one electron of the original 37 has left.

How many neon atoms are contained in (7.27x10^2) grams of neon?
statuscvo [17]

Answer: 2.19x10^25 atoms

Explanation:

Molar Mass of Neon = 20g/mol

1mole(20g) of Neon contains 6.02x10^23 atoms.

Therefore, 7.27x10^2g of Neon will contain x atoms i.e

X atoms = (7.27x10^2x6.02x10^23)/20 = 2.19x10^25 atoms

Vitamin D is produced in the skin when 7-dehydrocholesterol reacts with UVB rays (ultraviolet B) having wavelengths between
goblinko [34]

The energy range expected is 6.6 × 10^-19 J < E < 7.33 × 10^-19 J

The energy of the photon is given by;

E = hc/λ

E = energy of the photon

h = Plank's constant

c = speed of light

λ = wavelength of light

For the upper boundary range;

E = ?

h = 6.6 × 10^-34 Js

c = 3  × 10^8 m/s

λ = 270 × 10^-9

E =  6.6 × 10^-34 Js × 3  × 10^8 m/s / 270 × 10^-9

E = 7.33 × 10^-19 J

For the lower range;

E = ?

h = 6.6 × 10^-34 Js

c = 3  × 10^8 m/s

λ =300 × 10^-9

E =  6.6 × 10^-34 Js × 3  × 10^8 m/s / 300 × 10^-9

E = 6.6 × 10^-19 J

Hence, the energy range 6.6 × 10^-19 J < E <  7.33 × 10^-19 J

Count the total number of atoms in the chemical formula 5H2O2
SVEN [57.7K]

Answer:

20 atoms

Explanation:

There are 4 in H2O2 because of 2 hydrogens and 2 oxygens.

Then, multiply by 5 because the coefficient is 5, therefore there are 5 H2O2 molecules.

5 x 4 = 20

The graphs above show Maxwell-Boltzmann distributions for one-mole samples of Ar(g). Graph 1 shows the distribution of particle
Aleks [24]

The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature.

<h3>What is Maxwell-Boltzmann distributions?</h3>

The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature. Recall that at the same temperature, the relative speed of gas molecules is described by the  Maxwell-Boltzmann distributions.

The question is incomplete hence we can not be able to show the exact relationship between the two graphs in order to arrive at a justification for the student's claim.
