A homeowner uses two different short-term radon collection devices to measure the same space. One device measured the air for 4 days and the result was 1 pCi/L. The other device measured the air for 8 days and the result was 6 pCi/L. Calculate an estimate of the radon concentrations in the home, taking into consideration the different measurement periods.

Explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
