Answer:
<u>1092K</u>
Explanation:
We can use the combined gas law to answer this question:
P1V1/T1 = P2V2/T2,
where P, V and T are the Pressure, Volume, and Temperature for initial (1) and Final (2) conditions. Temperatures must be in Kelvin.
The problem states that V2 = 2V1 and P2 = 2P1.
Let's rearrange to solve for T2, which is the question:
T2 = T1(P2/P1)(V2/V1)
Note how the pressure and temperature values are written: as ratios. Enter the values:
T2 = (273K)(P2/P1)(V2/V1)
T2 = (273K)(2P1/P1)(2V1/V1) [Use the expressions for V2 and P2 from above]
T2 = (273K)(2)(2)
T2 = 1092K

Ans: 26 valence electrons
Explanation:To find the valence electrons, we need to add the valence electrons of the individual atom in the compound. Therefore, let us divide this question into 3 parts.
1) What is the number of valence electrons of Arsenic (As)?
2) What is the number of valence electrons of Oxygen (O)?
3) What is the total number of valence electrons of
1.
The number of valence electrons of Arsenic(As) = 5
2.
The number of valence electrons of Oxygen (O) = 6
3.
Since there are 3 atoms of Oxygen, and 3 extra electrons are also present in the shape of "3-", as it is an ion, therefore,
The total number of valence electrons of
= 5 + 6 * 3 + 3 =
26 valence electrons.
Ans: The total number of valence electrons in = 26.
