Volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.
<h3>What are volatile substances?</h3>
Volatile substances are substances which can easily vaporize or change to gaseous state.
Volatile substances can either be solids or liquids but are mostly liquids.
Example of volatile substances include ether, petrol, chocolate.
The presence of volatile substances can be detected by the gases they release which may have characteristic odors.
Therefore, volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.

In order to find the percent yield of a reaction, we need to use the theoretical yield and actual yield into a formula, which is the following:
%yield = (actual yield/theoretical yield)*100
Adding the values from the question in the formula:
%yield = (4.5/10.7)*100
%yield = 42
The percent yield for this reaction will be 42%
Answer:
Explanation:
1. First take the cylinder volume formula:
2. Then take the values for the radius and the height of the cylinder and replace them into the formula:
3. Solve the equation:
In balancing reactions, it is important to remember that each of the side in the reaction should have the same number of elements. We do as follows:
<span>2SO2(g) + O2(g) -> 2SO3(g)
H2S(g) + 3/2O2(g) -> SO2(g) + H2O(g)
Hope this answers the question. Have a nice day.</span>
