Calculate %ic of the interatomic bonds for the intermetallic compound al6mn.

We need to know the electronegatives of the elements in the compound which are Al and Mn as the %ic is an electronegative function. 
Electronegative of Al is 1.5
 Electronegative of Mn is 1.6
 %ic = [1 - exp(-0.25)(1.6 - 1.5)^2] x 100
 %ic = [1 - exp(-0.25)(0.01)] x 100
 %ic = 0.25%

The gas would begin to expand, and eventually the can would burst or explode.
