Which metal can replace another metal in a reaction? A. Any metal on the list can replace any other metal also on the list.
B. A metal on the activity series list will replace one that is not on the
list.
C. A metal lower on the activity series list will replace one that is
higher
D. A metal higher on the activity series list will replace one that is
Tower

D

Explanation:

The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.

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.
