#20: Short Answer Question (11 points) You are provided with 100 mL of an aqueous buffer that is 0.25 M in formic acid, HCO2H, a weak acid, and 0.25 M sodium formate, HCO2Na.  What is the pH of this buffer? Circle your answer.  To this solution, you have added 10.0 mL of a 0.2 M HNO3. Write out the reaction that occurs when HNO3 is added to the buffer.  Calculate the new concentrations of formic acid (HCO2H) and sodium formate (HCO2Na) in the solution. To receive partial credit show the setup of your stoichiometry table. Circle your answers for and {HCO2Na].  Calculate the pH of this solutions after the addition of HNO3. Circle your answer.    Academic Honesty Statement: I have completed this problem and have shown the computer my answer. I understand that any alteration to the answer that was shown to the camera before submission to my professor will result in no credit for this question.  By selecting “I agree” below, I am indicating that I have read, understand, and agree to these instructions.

Literature Concept: Point of View Or Culture Concept: Cultural Capital “There’s no way in hell I’d try that at a Garden Heights party though. You make a fool of yourself one time, and that’s it. Everybody in the neighborhood will know and nobody will forget. In Garden Heights, I learn how to be dope by watching. At Williamson, I put my learned dopeness on display. I’m not even that dope, but these white kids think I am and that goes a long way in high school politics.”

A bike wheel rotates revolutions. How many radians has it rotated?

A kg person riding a bike puts all her weight on each pedal when climbing a hill. The pedals rotate in a circle of radius cm. What is the maximum torque she exerts?

A merry-go-round with a moment of inertia equal to kg m2 and a radius of m rotates with negligiblefriction at rad/s. A child initially standing still next to the merry-go-round jumps onto the edge of the platform straight toward the axis of rotation, causing the platform to slow to rad/s.What is her mass?
