Question 1

An exothermic reaction causes the surroundings to
◦ increase in temperature
◦ become acidic.
◦ expand.
◦ decrease in temperature.
◦ release CO2.

Question 2

At 25°C, the following heats of reaction are known:
2ClF(g) + O2(g) → Cl2O(g) + F2O(g)
ΔH°rxn =  167.4 kJ/mol
2ClF3(g)  +  2O2(g) → Cl2O(g)  +  3F2O(g)
ΔH°rxn =  341.4 kJ/mol
2F2(g) + O2(g) → 2F2O(g)
ΔH°rxn =  –43.4 kJ/mol
At the same temperature, use the above data to calculate the heat released (kJ) when 3.40 moles of ClF(g) reacts with excess F2:
         ClF(g) + F2(g) → ClF3(g)

◦ 109 kJ
◦ 233 kJ
◦ 370. kJ
◦ 465 kJ
◦ 1,580  kJ

The cure for trichomoniasis is easy as long as the patient does not drink alcoholic beverages for 24 hours. Just a single dose of medication is needed to rid the body of the disease. However, without proper precautions, an individual may contract the disease repeatedly. In fact, most people develop trichomoniasis again within three months of their last treatment.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
