The closed reflux method is more efficient in the oxidation of volatile organic compounds than is the opened reflux method. The reason for this is that the oxidant is in contact with these compounds for a longer time. Besides, the closed method is cheaper as only 2 mL of sample is required, since 5 mL is the total volume of the mixture. This means that the amounts of reagents and sample are reduced by a factor of over 20 compared to the opened reflux method. In addition, this fact makes the method less contaminating and allows for the simultaneous digestion of a great number of samples
Closed means just that...not open and unable to allow sodium ions to flow. Inactivated means that they do not respond to the stimulus. They could be open or closed, but do not receive the signal from the messenger. Also refractory.
Neither of them affect mass in a closed system.
In HCP packing, atom planes are stacked in ABABAB form. IN CCP (a.k.a. FCC) packing, atom planes are stacked in ABCABC form.
Heating S in a closed environment where it reacts with nothing would be physical but burning S in an open environment it will react with O and is therefore chemical.
