Answer:
The frequency of light ranges from 430 trillion hertz to 750 trillion hertz
Explanation:
B. HE DETERMINED AN ELECTRONS CHARGE
Since O almost always has a charge of -2, the oxygen atoms have an overall charge of -8 (-2*4)
Since K has a charge of +1, that brings the overall charge to -7 (-8+1)
Then, in order for the overall charge to be 0, Mn would have to have a change of +7 (-7+7=0)
Hope this helps
