es the rest of the energy go? A. It is transformed into sound energy. B. It is transformed into light energy. C. It is transformed into electrical energy. D. It is transformed into magnetic energy.
<span>Fe atomic mass = 55.86
* 1 = 55.86
Cr atomic mass = 52
*2 = 104
O atomic mass = 16
* 4 = 64
Total molecular mass = 223.86
Percent by mass Fe = (55.86/223.86)*100 = 24.95%
Percent by mass Cr = 46.45%
Percent by mass O = 28.59%</span>
