Answer:
5.62 g of F2
Explanation:
We have to start with the chemical reaction:
<u>We have a balanced reaction</u>, so we can continue with the <u>mol calculation</u>. For this, we need to know the <u>molar mass</u> of (70.906 g/mol), so:
Now, with the <u>molar ratio</u> between and we can convert from moles of and (1:3), so:
Finally, with the <u>molar mass</u> of we can calculate the gram of (37.99 g/mol), so:
I hope it helps!
While ethanol being an alcohol does have a direct O−H connection. Hence, ethanol has intermolecular hydrogen bonds. Therefore, more stroger physical bonds have to be destroyed in ethanol, than in acetone. Hence, acetone evaporates faster than ethanol inspite of having higher surface tension.
<h3>What is Vapor pressure ?</h3>
The pressure that a vapour exerts on the condensed phases (solid or liquid) in a closed system when they are in thermodynamic equilibrium with one another is known as vapour pressure (or equilibrium vapour pressure).
- It is significant to remember that when a liquid boils, the pressure of its vapour equals the atmospheric pressure. For instance, the vapour pressure of water when it boils at sea level is 1 atmosphere because the surrounding pressure is also 1 atmosphere.

PROTON: Positive (+) charge. Relative mass of 1. Found in the nucleus.
NEUTRON: Neutral charge. Relative mass of 1. Found in the nucleus.
ELECTRON: Negative (-) charge. Relative mass of .0005. Found on the outside of the nucleus.
Chadwick proved the existence of neutrons - elementary particles devoid of any electrical charge.
Rutherford discovered alpha and beta rays and proposed the mass of radioactive decay. Postulated the nuclear structure of the atom.
J.J Thompson proposed the plum pudding model of the atom. Showed that all atoms contain tiny negatively charged subatomic particles or electrons.
