4.5 L
Explanation:
We will use the combined gas law formula;
P₁V₁/T₁ = P₂V₂/T₂
Because the pressure remains the same, it cancels out and what remains is;
V₁/T₁ = V₂/T₂
Before evaluating remember to change the temperatures into Kelvin;
-23° = 250.15 K
177° = 450.15 K
We replace the variables with known values;
2.5 / 250.15 = V₂ / 450.15
V₂ = 2.5 /250.15 * 450.15
V₂ = 4.4988 L
≅ 4.5 L
<h2>Hello!</h2>
The answer is: -97.37° C
<h2>Why?</h2>
According to the Charles and Gay-Lussac's Law we have that:
Where:
<em>v</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
From the Gay-Lussac's Law we also have the following relation:
Since we need to find the new temperature (T2) we can use the last equation:
We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:
So, the temperature is -97.37° C
Have a nice day!
I think the answer is 1s²2s²2p⁶. Since neon has an atomic number of 10, we know that it needs to have 10 electrons and since it is in the second row it cannot have any d electrons which makes the first option incorrect. The second option is incorrect because the 2s⁴ can't exist since s orbitals can only hold 2 electrons. The fourth option cannot be right because it again neon cannot have d electrons due to it being in the second row.
I hope this helps. Let me know if anything is unclear.
