You are a crime scene investigator who has been called to the scene of an apparent chemical attack. You are asked to determine what type of chemical agents are present. You have a full set of colorimetric tubes. Explain in detail the process of identifying the chemicals that are present by using the colorimetric tubes. Specifically include procedures for your self-protection in the chemical hazard zone.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

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.
