Free Respоnse: Belоw аll оf the free response questions for this exаm аre listed. You should work all of the free responses completely before exiting the Canvas quiz. You only need to type your final answer for each question into the essay box below. Once you have closed the quiz, then you can use your cell phone to take pictures of your free response work and then can upload this to the assignment labelled “Free Response Exam 3 Unit 4 Part 2” as a pdf or word document. You will have 10 minutes from the time you finish the Canvas quiz closes to upload. Note that no credit will be given for a free response question without both the answer typed into the box (matching your work) and the work upload. If the quiz times out before you get to type in an answer, e-mail me your final answer (or as far as you got for the question) immediately. The quiz is time stamped, so I will know whether you sent it immediately or took additional time to work on it outside of the Canvas quiz. A periodic table and important equations and conversions are included below:NA = 6.022 x 1023M1V1=M2V2 Free Response 1: If 17.2 grams of Ge is combined with 89.4 grams F2, according to the reaction:Ge + F2 GeF4i. Determine the mass of GeF4 expected to be formed. All work must be shown and uploaded to receive credit (6 points)ii. Determine the mass of excess reagent left if the reaction above proceeds as much as possible. (6 points) Free Response 2: Complete combustion of a 75.80 gram sample containing C, H, and O results in the formation of 182.17 grams of CO2 and 63.93 grams of H2O. Determine the empirical formula of the compound. (8 points) Free Response 3: Calcium nitride reacts with water to from calcium oxide and ammonia according to the chemical reaction below.
