Can someone please help me with my chem final!!

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?
