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.

Seltzer water is created by placing water under pressure with carbon dioxide gas. which of the following statements best describe seltzer water: a. the solution will be slightly acidic b. the solution will be slightly basic. the solution will be strongly acidic. d. the solution will be strongly basic. e. the solution will be neutral

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
