1.64 L of sulfur dioxide (SO₂)
Explanation:
We have the following chemical reaction:
S (s) + O₂ (g) → SO₂ (g)
First we calculate the number of moles of sulfur (S):
number of moles = mass / molar weight
number of moles of sulfur = 2.35 / 32 = 0.0734 moles
Looking at the chemical reaction we see that 1 moles of sulfur (S) produces 1 moles of sulfur dioxide (SO₂), so 0.0734 moles of sulfur will produce 0.0734 moles of sulfur dioxide (SO₂).
To calculate the volume of sulfur dioxide (SO₂), assuming that the sulfur dioxide is behaving as an ideal gas and the we determine the gas volume under standard temperature and pressure conditions, we use the following formula:
number of moles = volume / 22.4 (L/mole)
volume = number of moles × 22.4
volume of SO₂ = 0.0734 × 22.4 = 1.64 L

PS: I appreciate that you took the time and effort to write the chemical equation in a readable way. This makes the question to be very rare :D
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
Answer:
310.69K
Explanation:
Given parameters:
Initial temperature T₁ = 292K
Initial pressure P₁ = 1.25atm
Final pressure P₂ = 1.33atm
Unknown:
Final temperature T₂ = ?
Solution
To find the unkown, we need to apply the combined gas law. From the combined gas law, it can be deduced that at constant volume, the pressure of a give mass or mole of gas varies directly with the absolute temperature.
Since the same aerosol can is heated, the volume is constant.
= 
Now, we have to make T₂ the subject of the formula:
T₂ = 
T₂ = 
= 310.69K
