Which psychoactive drugs are are responsible for the most deaths in the United States? In your answer be sure to touch on both “Acute” and “Chronic” toxicity. In addition, what is the legal status of these psychoactive drugs?  

(06.04 MC) What is the mass of 3.15 liters of N2 gas at STP?

A drug’s potency dictates how much is needed to cause an effect.

(06.02 MC) A substance has a melting point of 80 °C. Which of the following is true for the substance?

(05.02 MC) How many moles of Na2SO4 are present in 284.078 grams of Na2SO4?

(05.04 MC) Based on the equation, how many grams of Br2 are required to react completely with 36.2 grams of AlCl3?2AlCl3 + 3Br2 → 2AlBr3 + 3Cl2

(07.01 LC) Which of the following happens during an exothermic chemical change?

(06.02 LC) What happens to the particles of a gas when the gas changes into a liquid?

(08.02 MC) A 0.0200 M NaCl solution was formed when 38.0 grams of NaCl was dissolved in enough water. What was the total volume of the solution formed?

(06.04 HC) Part 1. A chemist reacted 18.0 liters of F2 gas with NaCl in the laboratory to form Cl2 gas and NaF. Use the ideal gas law equation to determine the mass of NaCl that reacted with F2 at 290. K and 1.5 atm.F2 + 2NaCl → Cl2 + 2NaFPart 2. Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.
