Please help me with this. It asked you to determine the heat change in the reaction CH4+Cl2-> CH3Cl + HCl
You were given the bond energy of C-H= 414 kj/mol C-Cl= 244 kj/mol And the bond energy of H-Cl= 431 kj/mol
How do you find the bond energy of CH3Cl then?​

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

let that person have a turn to speak : )
