When I₂(g) reacts with Cl₂(g) to form ICI(g), 6.41 kcal of energy are evolved for each mole of I₂(g) that reacts. Write a balanced equation for the reaction with an energy term in kcal as part of the equation. Use the SMALLEST INTEGER coefficients possible and put the energy term in an appropriate box. If a box is not needed, leave it blank. $ R Submit Answer DOD 000 F4 % 5 + T F5 Retry Entire Group 9 more group attempts.remaining A + Cengage Learning Cengage Technical Support 6 MacBook Air M F6 Y & 7 -> aa F7 Ü 8 DII F8 ( 9 + DD F9 0 :) 0 J F10 P Previous 0 { Next> Save and Exit F12 } Update delete
