Answer: Volume occupied by 3.00 moles of oxygen gas under the same condition is 3.75 L.
Explanation:
Given:
= 4.00 moles,
= 5.0 L
= 3.00 moles,
= ?
Formula used is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that volume occupied by 3.00 moles of oxygen gas under the same condition is 3.75 L.

Hello there,
In a hydrogen the neutrons and protons are as follows:
Now with a hydrogen with a -3 isotope:
- 3 - 1 = 2 which means that you have 2 neutrons
A hydrogen with a -3 isotope would have 1 proton and 2 neutrons.
Hope I helped,

Answer: electronic configuration
Explanation:
H₂S
<h3>Further explanation</h3>
Given
ΔH fusion and ΔH vaporization of different substances
Required
The substance absorbs 58.16 kJ of energy when 3.11 mol vaporizes
Solution
We can use the formula :

Q=heat/energy absorbed
n = moles
The heat absorbed : 58.16 kJ
moles = 3.11
so ΔH vaporization :

The correct substance which has ΔH vaporization = 18.7 kj / mol is H₂S
(H₂S from the data above has ΔH fusion = 2.37 kj / mol and ΔH vaporization = 18.7 kj / mol)
