Sketch the galvanic cell based on the following half reactions. Show the direction of electron flow, show the direction of ion migration through the salt bridge, and identify the cathode and anode. Give the overall balanced reaction, and determine the cell potential. Assume all concentrations are 1.0M and all partial pressures are 1.0 atm. IO3^-(aq) + Fe2+ ⇌ Fe3^+ I2(aq)
Zn(s) + Ag^+ ⇌Zn^2+(aq) + Ag(s)

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

it's c. elements are placed in rows based on how may valencies electrons have.
