Type the half-cell reaction that takes place at the anode for the cobalt-silver voltaic cell. indicate the physical states of atoms and ions using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively. use (aq) for an aqueous solution. do not include phases for electrons.

Co(s)→Co3+(aq)+3e−

Explanation:

The half-cell reaction may be defied as the reaction taking place at an individual anode or cathode. The oxidation and reduction reactions occur at the electrodes.

Oxidation reaction occur at anode and reduction reaction at cathode. The half-cell reaction for cobalt silver voltaic cell, the oxidation of cobalt occurs at anode. The cobalt loses its 3 electrons and converted to aqueous state from the solid state.

Thus, the reaction at anode is Co(s)→Co3+(aq)+3e− .

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
