As said by your friends, the said reaction is a displacement reaction. when I plug in the numbers in the formula, my answer was 9.45. A) Calculate the number of moles of NO2, F2, and NO2F after 10.0 s if 2.00 mol of NO2 is mixed with, 3. A. a. Synthesis gas is one of the most widely used industrial chemicals, and is the major industrial source of hydrogen. Acarrentalcompanyusesthefollowingtabletohelpcomputerentalfees. What assumptions are made to complete the, Analysis of a reaction mixture showed that it had the composition 0.43 mol/L N2, 0.541 mol/L H2, and 0.124 mol/L NH3 at 800 K, at which temperature Kc=0.278 for N2(g) + 3H2(g)2NH3(g). (i follow the directions all i had to do is plotted the point which i got a trapazid) I determined the type of, The concentration of lead ions (Pb^2+) in a sample of polluted water that also contains nitrate ions (NO3) is determined by adding solid sodium sulfate (Na2SO4) to the sample of the water. X+Y2Z+heat the concentration of the product could be increased by 1.adding a catalyst 2.adding more heat to the system 3.increasing the concentration of Y 4.decreasing the concentration of X. Would the reaction be SN1 or SN2? mols = grams/molar mass. b. A strong acid as is HCl reacts with water HCl + H2O = H3O + + Cl-.
