Mar 09, 2011 · b. The reaction intermediate is COCl - it is produced during the first step but immediately used up in the second step.: c. The catalyst is Cl - a catalyst can be identified by the fact that it is added as a reactant but emerges (as a product) unchanged; thus it will always first appear as a reactant but will later (not necessarily the next step) appear as a product in the reaction. In a certain experiment 2.00 moles of NH3(g) and 10.00 moles. of O2(g) are contained in a closed flask. After the reaction is. complete, 6.75 moles of O2(g) remains. Calculate the number. of moles of NO(g) in the product mixture: (Hint: You cannot. do this problem by adding the balanced equations because you
2 Set the MicroLab collection increment to 5 seconds, using the detailed instructions provided in the lab. 3 Measure about 40 mL of deionized water with a graduated cylinder and add to a 150 mL beaker and heat to between 60 and 70 C. Work on steps 4 and 5 while the water is heating.
