The effective number of bonds between N and O is 1.33. The greater the effective number of bonds, the shorter the N–O bond length. (b) The CH2F2 molecule is polar, whereas the CF4 molecule is not. The molecular geometry in both CH2F2 and CF4 is tetrahedral (or the same). The C-F bond is polar.1. Solid carbon and carbon dioxide gas at 1,160 K were placed in a rigid 2.00 L container, and the reaction represented above occurred. As the reaction proceeded, the total pressure in the container was monitored. When equilibrium was reached, there was still some C(s) remaining in the container.6. The following questions refer to the electrochemical cell shown in the diagram above. (a) Write a balanced net ionic equation for the spontaneous reaction that takes place in the cell. Zn2+(aq) + 2 Ag(s) (b) Calculate the standard cell potential, E °, for the reaction in part (a).It's great that you're focused on the FRQ section of the AP Chem exam. Performing well on this section can make a considerable difference in your overall score. Here are some tips and strategies to improve your FRQ skills: 1. Familiarize yourself with the FRQ format: Start by understanding the types of FRQs you can expect on the exam.

The mixture of the hydrocarbon and oxygen is sparked so that a complete combustion reaction occurs, producing CO2(g) and H2O(g). The partial pressures of these gases at 127°C are 0.600 atm for CO2(g) and 0.800 atm for H2O(g). There is O2(g) remaining in the container after the reaction is complete.
