Answer:
At temperatures below −78 °C, carbon dioxide changes directly from a gas to a white solid called dry ice through a process called deposition.
Answer: The time is 0.69/k seconds
Explanation:
The following integrated first order rate law
ln[SO₂Cl₂] - ln[SO₂Cl₂]₀ = - k×t
where
[SO₂Cl₂] concentration at time t,
[SO₂Cl₂]₀ initial concentration,
k rate constant
Therefore, the time elapsed after a certain concentration variation is given by:
![t=\frac{ln[SO_{2}Cl_{2}]_{0} - ln[SO_{2}Cl_{2}]}{k}=\frac{ln\frac{[SO_{2}Cl_{2}]_{0}}{[SO_{2}Cl_{2}]} }{k}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bln%5BSO_%7B2%7DCl_%7B2%7D%5D_%7B0%7D%20-%20ln%5BSO_%7B2%7DCl_%7B2%7D%5D%7D%7Bk%7D%3D%5Cfrac%7Bln%5Cfrac%7B%5BSO_%7B2%7DCl_%7B2%7D%5D_%7B0%7D%7D%7B%5BSO_%7B2%7DCl_%7B2%7D%5D%7D%20%7D%7Bk%7D)
We could assume that SO₂Cl₂ behaves as a ideal gas mixture so partial pressure is proportional to concentration:

![[SO_{2}Cl_{2}]= \frac{n_{(SO_{2}Cl_{2})}}{V}}=\frac{p_{(SO_{2}Cl_{2})}}{RT}}](https://tex.z-dn.net/?f=%5BSO_%7B2%7DCl_%7B2%7D%5D%3D%20%5Cfrac%7Bn_%7B%28SO_%7B2%7DCl_%7B2%7D%29%7D%7D%7BV%7D%7D%3D%5Cfrac%7Bp_%7B%28SO_%7B2%7DCl_%7B2%7D%29%7D%7D%7BRT%7D%7D)
In conclusion,
t = ln( p(SO₂Cl₂)₀/p(SO₂Cl₂) )/k

<h2>Answer:</h2>
Plasma
<h2>Explanation:</h2>
Plasma is the stuff of lightning, flame and stars. Plasma is neither solid, liquid nor gas plasma is a fourth state of matter.
Plasma is when the electrons are "freed" from their host atoms for a short time, due to high temperatures. Fire is plasma, it responds to electric fields. Lightning is also plasma.
Answer:

Explanation:
Hello,
At first, consider the chemical reaction:

Now, considering the ideal gas equation, we compute the total moles:

Then, taking into account that the total moles are stoichiometrically handed out by the half (0.05625mol), one can say that:

Thus, the molar fractions are:

Finally, the partial pressures are:
