The normal sublimation point of solid acetylene is -84 C. Figure out the answers to the questions below and then pick the correct statement from the multiple choices(i) Is the sublimation of solid acetylene an endothermic or an exothermic process? (i) Is the sublimation of solid acetylene an endothermic or an exothermic process? (ii) In what temperature range is the sublimation of solid acetylene a spontaneous process? (iii) In what temperature range is this process a nonspontaneous process? (iv) In what temperature range are the two phases involved in the sublimation of solid acetylene in equilibrium? a) In (iv) the two phases involved in the sublimation of solid acetylene are in equilibrium when the temperature equals -84 oC. b) In (ii) the sublimation of solid acetylene is a spontaneous process at temperatures below -84 oC. c) In (i) the sublimation of solid acetylene is an exothermic process. d) In (iv) the two phases involved in the sublimation of solid acetylene are in equilibrium at temperatures below -84 oC. e) In (iii) the sublimation of solid acetylene is a nonspontaneous process at temperatures above -84 oC.
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
A 4.5 g nugget of gold absorbed 276 j of heat. What was the final temperature of the gold if the initial temperature was 25 OC ? The specific heat of gold is 0.129 j/g OC.
For each of the following three questions 25.0 mL of 0.100 M pyridine (Kb = 1.70 x 10-9) is titrated with 0.100 M HCl. For each question calculate the pH of the final solution after the indicated amount of HCl has been added. That is, treat each q..
Two types of electrochemical cells which are based on thermodynamic principles can be described. Which of the following statements about these cells is correct
A latex balloon, inflated to an excess pressure of 1kPa and a radius of 30cm, is attached to a smooth nozzle, initially stoppered. The stopper is removed, and the balloon deflates in 5 seconds.
