A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.
Answer:
Bromine
Explanation:
To identify the gas, you first need to find the moles of the gas. You can do this using the Ideal Gas Law:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas Constant (0.08206 atm*L/mol *K)
-----> T = temperature (K)
After converting mL to L and Celsius to Kelvin, you can plug the values into the equation and simplify to find the moles.
P = 1.98 atm R = 0.08206 atm*L/mol *K
V = 752 mL / 1,000 = 0.752 L T = 62 °C + 273.15 = 335.15 K
n = ? moles
PV = nRT
(1.98 atm)(0.752 L) = n(0.08206 atm*L/mol *K)(335.15 K)
1.48896 = n(27.5024)
0.0541 = n
You can identify the gas by determining the molar mass of the gas, which is specific to each element. The molar mass exists as a ratio that compares the mass per 1 mole.
Molar Mass = mass / moles
Molar Mass = 4.32 g / 0.0541 moles
Molar Mass = 79.8 g/mol
This molar mass is closest to the molar mass of bromine (79.904 g/mol).
According to this question, a substance with a high volatility readily evaporates.
<h3>What is volatility?</h3>
Volatility is the characteristics of a material which describes how readily the material undergo vaporization.
Volatile substances readily change phase from solid or liquid to gases via the process of vaporization.
Therefore, according to this question, a substance with a high volatility readily evaporates.

C) can give up electrons more readily than others.
Oxidation is a process when an atom, a group of atoms, or an ion loses electrons.
For example,
Cu⁰ -------> Cu⁺² + 2e⁻. This is an oxidation process.
As we can see an oxidation number was 0, and it became +2. The oxidation number is increased. Oxidation number of the atom, when an atom has undergone oxidation, increases.
So, answer is b.False.
