The measures of two angles of ABC (shown in the illustration) are given. Find the measure of the third angle, if  m(∠A) = 130.3º and m(∠B) = 40.3º.  

A sample of solid sodium bicarbonate, NaHCO3,  is placed in a closed 1.0 L vessel at 398 K and allowed to decompose unil it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.250 What is the partial pressure of CO (in atm)  at equilibrium?

Consider the reaction of elemental bromine with elemental chlorine to form a bromochloride compound at a given temperature:                                          Br2(g)  +  Cl2(g)   ⇌   2 BrCl(g)       KP = 81.0 A closed vessel is charged with 1.20 atm of Br2(g) and 1.20 atm of Cl2(g) initially and allowed to reach equilibrium. What is the partial pressure of the BrCl (in atm) at that equilibrium? Hint: BrCl has a coefficient of 2.   

A physician has ordered peak and trough levels of a medication. When would the nurse schedule the peak level specimen?

Suppose that an endothermic reaction is at equilibrium. According to Le Chatelier’s Principle, what will cause the equilbrium to shift to the left, towards the reactants?

  The University of Cincinnati and I hold you to a very high standard for academic honesty. You must take all your tests without any assistance from others and according to the instructions provided. You are NOT allowed to use any outside resources. Individuals found to have violated this honor code will be sanctioned by the university. The highest penalty is academic dismissal. By typing your name in the space below, you agree that you have read and agree to the above conditions. Your exam will NOT be graded without an electronic signature.

Consider the reaction of elemental bromine with elemental chlorine to produce a bromochloride compound at a given temperature:                                          Br2(g)  +  Cl2(g)   ⇌   2 BrCl(g)       KP = 81.0 A closed vessel is charged with 2.10 atm of Br2(g) and 2.10 atm of Cl2(g) initially and allowed to reach equilibrium. What is the partial pressure of the BrCl (in atm) at that equilibrium? Hint: BrCl has a coefficient of 2.   

A sample of solid sodium bicarbonate, NaHCO3, is placed in a closed 1.0 L vessel at 398 K and allowed to decompose until it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.250 What is the partial pressure of CO (in atm)  at equilibrium?
