please and please choose the right answer and please make it clear for my understanding 1-Which of the following statements are false? Oxidation and reduction half-reactions occur at electrodes in electrochemical cells All electrochemical reactions involve the transfer of electrons Oxidation occurs at the anode All voltaic (galvanic) cells involve the use of electricity to initiate nonspontaneous chemical reactions Reduction occurs at the cathode 2-During the electrolysis of aqueous KCl solution using inert electrodes, gaseous hydrogen is evolved at one...

Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
