Assignment: Chemical Reactions You've reached the end of the unit on chemical reactions. You've learned all about classifying and balancing chemical reactions.; you've also learned some of the real world applications involving them. In this assignment, demonstrate your understanding of chemical reactions by completing a problem set. Instructions Your task is to complete the questions in the problem set. Read each question carefully, and provide rationale where required. Questions 1.Classify each of the following as a single displacement or double displacement reactions. Then, predict the products of each reaction, and provide the balanced equation. (2 marks each) a.
Cl_(2(g))+CsBr_((aq))->b.
AgNO_(3(aq))+Na_(2)CrO_(4(aq))->c.
MgCl_(2(aq))+AgNO_(3(aq))->d.
F_(2(g))+NaI_((aq))->2.While on vacation in Ecuador, you decide to rent a jeep and drive from your coastal resort into the Andes Mountains. The trip to your mountain vista goes smoothly, allowing you to catch the setting sun over the ocean. As twilight approaches, you jump back into your jeep and prepare to return to your resort. As you turn the key, the engine turns over but struggles to start. Once in gear, you notice that the engine does not have much power and there is a hint of black smoke coming out the exhaust. As you are slowly driving down the mountain, you start to think about combustion. Assuming there is nothing wrong with the jeep or the gasoline, what is the most likely explanation for the loss of power and hint of soot in the exhaust? (3 marks) Ammonium dichromate,
(NH_(4))_(2)Cr_(2)O_(7(s)), is a chemical compound that decomposes when heated to produce solid chromium(III) oxide,
Cr_(2)O_(3), nitrogen gas, and water vapor. Ammonium dichromate is commonly known as Vesuvian Fire, after Mount Vesuvius in Italy. During the decomposition reaction, the rapid expansion of nitrogen gas and water vapor sprays chromium(III) oxide in such a way that it resembles the spouting of molten lava and ash that occurs during a volcanic eruption. Write the balanced chemical equation for this reaction. (2 marks) Most people associate combustion with the production of fire or a flame, however, combustion reactions can produce energy in other forms. For example, in the human body glucose
(C_(6)H_(12)O_(6(s)))reacts with oxygen to produce energy that can be used by the body. a. Predict the products of the complete combustion of glucose. (1 mark) b. Write a balanced equation for the complete combustion of glucose in the human body. (1 mark) Your submission should include the following: Your answers to the problem set
