3


question:
Question: In the framework of the treatment of Generalized Anxiety, we distinguish (eg, Dugas and Ladouceur, 1997) between concerns about events based on reality, in which case the patient would be trained in problem solving, and concerns about events not based on reality and highly improbable that should be addressed by employing: 
 Options:  <1> Cognitive functional exposure. <2> Applied relaxation <3> Distraction techniques. <4> Meditation. <5> Self instructions
answer:
1


question:
Question: Ethylenediaminetetraacetic acid (EDTA) is a chelating agent widely used as a titrator in complexometric assessments that are characterized by: 
 Options:  <1> To make possible the EDTA titration of many metals in alkaline solutions an auxiliary complexing agent is used which prevents the metal ion from precipitating as hydroxide. <2> EDTA forms complexes of 1: 2 stoichiometry with some metal ions and therefore has a poor application in quantitative analysis. <3> It is important to choose an adequate pH to carry out the titration because metal-EDTA complexes are more stable at low pH than at high pH. <4> When evaluating a metal ion with EDTA, there is an excess of EDTA at the equivalence point. <5> When evaluating a metal ion with EDTA, there is an excess of metallic ion at the equivalence point.
answer:

1
