2011 midterm Q6 B

Postby Joann Hernandez 2F » Sun Feb 07, 2016 4:09 pm

When writing the final balanced equation, why did we have to multiply 2 to both Rb and Rb+? is it because of the electrons when you put them together?

yes you multiply two to Rb because you have to balance the charges of the electrons from F2+2e--->2F, so that the electrons cancel out and you are left with a balanced equationl of F2+2Rb--->2F- + 2Rb+
