Problem 126

Nitromethane, CH3NO2, can be used as a fuel. When the liquid is burned, the (unbalanced) reaction is mainly a. The standard enthalpy change of reaction (Hrxn) for the balanced reaction (with lowest whole-number coefficients) is 1288.5 kJ. Calculate the Hf for nitromethane. b. A 15.0-L flask containing a sample of nitromethane is filled with O2 and the flask is heated to 100.C. At this temperature, and after the reaction is complete, the total pressure of all the gases inside the flask is 950. torr. If the mole fraction of nitrogen ( ) is 0.134 after the reaction is complete, what mass of nitrogen was produced?

Step-by-Step Solution:
Step 1 of 3

Tuesday 1/12 Lecture Chapter 2 - Atoms compose all matter. An atom is the smallest identifiable unit of an element. Laws: 1. Law of Conservation of Mass: - “In a chemical reaction, matter is neither created nor destroyed” 2. Law of Definite Proportions - “All samples of a given compound have the same proportions of their constituent elements regardless of source” 3. Law of Multiple Proportions - “An atom of A combines with one, two, three or more atoms of B” - (e.g.) Amt. of C in grams Amt. of O in grams Carbon dioxide CO^2 1 g 2.67 g Carbon monoxide CO 1 g
