4* 23 g Na --------> 16 g O₂
9.5 g Na ------------> ?
Mass of O₂ = 9.5 * 16 / 4 * 23
Mass = 152 / 92
Mass = 1.6521 g of O₂
Molar mass O₂ = 16.0 g/mol
1 mole O₂ ------------ 16.0 g
? mole O₂ ------------ 1.6521 g
mole O₂ = 1.6521 * 1 / 16.0
≈ 0.10325 moles of O₂
hope this helps!

The value of the heat of combustion (H) that is calculated here is a chemical property.
<h3>What is the heat of combustion?</h3>
The heat of combustion is the energy that is given up when a substance is burnt in a calorimeter. The heat of combustion is often measured by the use of a calorimeter.
Hence, the value of the heat of combustion (H) that is calculated here is a chemical property.

Answer:
Attraction
(e-) ---> <--- (H+)
Repulsion:
<---(e-) (e-)-->
Neutral:
(e-) (Helium)
Explanation:
Accordingly to coulomb's law:
In the attraction, the hydrogen without an electron has a positive charge and needs to be fulfilled with a negative charge found in an eletron.
In the repulsion, both electrons has the same charge and repulse each other.
In the neutral case, the Helium is highly stable therefore the electron is not attracted.
