Fluorine gas consists of diatomic molecules of fluorine (F2). How many molecules of fluorine are in one mole of fluorine?

1 answer:

8 0

One mole of a substance contains 6.02 × 10²³ particles
If we are considering Fluorine gas, one mole contains 6.02 × 10²³ molecules
*note: to calculate the number of Fluorine atoms, we multiply by 2 because two atoms in each molecule*

Which of the elements has the same lewis structure as sulfur?

professor190 [17]

The answer is Oxygen. The elements that has the same lewis structure as sulfur is Oxygen. This is due to the fact that although the two compounds have different electronic configurations, the two have the same arrangement of electrons in their outermost orbits.

Leucippus and Democritus proposed the "first" atomic view of matter. They arrived at this view based on

erik [133]

Answer:

C) philosophical and intuitive speculation

Explanation:

Leucippus and Democritus proposed the concept of an atom based on philosophical speculation as a way of explaining reality with the scarcity of data available at that time.

The ideas of Leucippus and Democritus were rejected at that time but later retaken by Dalton when proposing his atomic model.

An atom of 105In has a mass of 104.914558 amu. Calculate the binding energy in MeV per NUCLEON. Enter your answer with 3 signifi

joja [24]

Answer:

8.46

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

Also, atomic number of I = 549

Thus, the number of protons = 49

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Mass number = Number of protons + Number of neutrons

105 = 49 + Number of neutrons

Number of neutrons = 56

Mass of neutron = 1.008665 amu

Mass of proton = 1.007825 amu

Calculated mass = Number of protons*Mass of proton + Number of neutrons*Mass of neutron

Thus,

Calculated mass = (49*1.007825 + 56*1.008665) amu = 105.868665 amu

Mass defect = Δm = |105.868665 - 104.914558| amu = 0.954107 amu

The conversion of amu to MeV is shown below as:-

1 amu = 931.5 MeV

So, Energy = 0.954107*931.5 MeV/atom = 888.750671 MeV/atom

Also, 1 atom has 105 nucleons (Protons+neutrons)

So, Energy = 888.750671 MeV/105nucleons = 8.46 MeV/nucleon
