We can use the combined gas law equation to find the new pressure of the gas.
where P - pressure
V - volume
T - temperature
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
P1 - 795 mm Hg x 0.0013 atm/ mm Hg = 1.033 atm
T1 - 23.5 °C + 273 = 296.5 K
T2 - 31.7 °C + 273 = 304.7 K
substituting the values in the equation
P = 0.712 atm
the answer closest to this value is A) 0.723 atm
therefore answer is
<span>A) 0.723 atm</span>

The cis and Trans-forms of hyponitrous acid are given below in the attached document.
Hyponitrous acid has the chemical formula H2N2O2 or HON=NOH. 62.028 g/mol is the molecular weight of it. Additionally, it can take either a trans or cis form. When dry, the trans-hyponitrous acid crystallizes into white, explosive particles. Additionally, it has a half-life of 16 days at 25oC at a pH 1-3 in aqueous solution and is a weak acid (pKa1=7.21, pKa2=11.54). It decomposes into nitrous oxide and water. It is incorrect to think of N2O as the anhydride of H2N2O2. However, even though cis acid is unknown, we can still get its sodium salts.

Answer:
The energy of a wave is inversely proportional to the wavelength of the wave.
As wavelength increases, the energy of the wave decreases.
As wavelength decreases, the energy of the wave increases.
Explanation:
The energy of a wave is directly proportional to the wave's frequency. As frequency increases, so does the energy of the wave.
(energy
is proportional to frequency
)
<u>How is this related to wavelength?</u>
Frequency is inversely proportional to wavelength. That means that as frequency increases, wavelength decreases and as frequency decreases, wavelength increases.
(frequency
is inversely proportional to wavelength
)
Therefore, as wavelength increases, the energy of a wave decreases and as wavelength decreases, the energy of a wave increases.
