General Chemistry 1035 Homework 3 Due on Sept 23 in class 1. The chemical equation 2CO 2 2CO + O 2 informs us that (A) when 2 mol of CO 2 decompose, less than 2 mol of CO will be formed and the quantity of O 2 formed will be less than 1 mol. (B) only under special conditions will 2 mol of CO 2 yield 2 mol of CO and l mol of O 2 . (C) carbon dioxide decomposes, but that the relative amounts of CO 2 , CO, and O 2 involved in the reaction are a function of conditions. (D) regardless of conditions, the decomposition of l mol of CO 2 will yield l mol of CO and 1/ 2 mole of O 2 . (E) the tendency of CO 2 to decompose is equal to the tendency of CO and O 2 to combine. 2. When an electric discharge is passed through boron trichloride a new compound is formed. What is its simplest formula if on analysis it is shown to contain 0.0878 g of chlorine and 0.0131 g of boron? (A) BCl (B) BCl 2 (C) BCl 3 (D) B 2 Cl 3 3. A compound is found to consist of 34.9% sodium, 16.4% boron and 48.6% oxygen. Its simplest formula is (A) NaBO 2 (D) Na 3 BO 3 (B) NaBO 3 (E) Na 3 BO 4 (C) Na 2 B 4 O 7
