Insert numbers next to these steps to show the correct order of events for a fuel cell to work. (1 - first step, 5 - last step). At the anode, the H2 loses electrons and becomes H+

At the cathode, H+ ions combine with electrons and O2 to produce H2O.

Electrons (e-) flow through the wire to produce electricity.

Fuel (H2) is pumped into the cell.

H+ flows through the electrolyte to the cathode.

Which sentence best describes the formation of igneous rock? a- lava on the surface dries up and makes arock b_melted rocks cools and forms crystals c_rocks under tremendous heat and pressure d_magma is melted rock underground

What is the overall order of reaction for rate = k[no]2[o2]

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
