The correct answer really is B.
If you are directed to break that rule then you better be in a high level chemistry class. When I taught things like that I insisted that students just wait until the chemical permeated the fume cabinet and even then I was always very nervous.
Sometimes you have to know when to ignore a bad direction. If you are working with chlorine, for example, you should be especially careful. That stuff was used in WWI as part of a chemical warfare technique. Many men suffered grotesque deaths by breathing it in, particularly if they were in trenches. Chlorine is heavier than air. It sinks to the lowest level.
Answer:
Final volume is 1.29cm³
Explanation:
Using combined gas law:
P₁V₁/T₁ = P₂V₂/T₂
<em>Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of a gas.</em>
<em />
We can solve the volume of the gas:
P₁ = 1atm at STP
V₁ = 1cm³
T₁ = 273.15K at STP
P₂ = 710mmHg * (1atm / 760mmHg) = 0.9342atm
V₂ = ?
T₂ = 55.0°C + 273.15K = 328.15K
Replacing:
1atm*1cm³/273.15K = 0.9342atm*V₂/328.15K
1.29cm³ = V₂
<h3>Final volume is 1.29cm³</h3>

Answer:
Activation Energy is the Energy that Must be Overcome/reached by Reactants for Products to be formed.
I'd go with the 2nd Option.
