Name: Nate Stults College ID:0641016 Thomas Edison State University General Chemistry I with Labs (CHE-121) Section no.: 4 Semester and year: Feb 2019 Written Assignment 4: Chemical Reactions Answer all assigned questions and problems, and show all work. 1. Write the (a) balanced equation for the formation of liquid water from hydrogen and oxygen gas, and use it to explain the following terms: (b) chemical reaction, (c) reactant, (d) product. (12 points) A) 2 H 2 + O 2 2 H 2 O B) A bond that either combines or separates an element or compound. C) Located on the left side of the arrow, they are the elements/chemicals that will react to each other to form something else. D) Located on the right side of the arrow, these are the results of the reactants after they react. 2. Balance the following equations: (18 points) a. 2C + O 2 2CO b. 2CO + O 2 2CO 2 c. 2Na + 2H 2 O H 2 + 2NaOH d. Zn + 2HCl ZnCl 2 + H 2 e. 2NaOH + H 2 SO 4 2H 2 O + Na 2 SO 4 f. 2NH 3 + 2CuO 2Cu + N 2 + 3H 2 O 3. Calculate the mass in grams of iodine (I 2 ) that will react completely with 20.4 g of aluminum (Al) to form aluminum iodide (AlI 3 ). (5 points) I 2 + Al→ Al I 3 = 3 I 2 + 2 Al → 2 Al I 3 # of moles=mass/molar mass (Al)20.4/26.98=.756 Moles Al- 2(.756)+I 3(.756) so 3(.756)=2.268 Moles Mass of Iodine= Moles X Molar Mass 2.268 X 126.9= 287g (Reference: Chang 3.47) 1 Copyright © 2017 by Thomas Edison State University .
