Answer

Explanation:

Step1: Identify number of C - H bonds in $CH_4$

A methane molecule ($CH_4$) has 4 C - H bonds.

Step2: Calculate total energy

The energy required to break one C - H bond is 413 kJ/mol. For 4 C - H bonds in 1 mole of $CH_4$, we multiply the energy per bond by the number of bonds. So the total energy $E=4\times413$ kJ/mol. $E = 1652$ kJ/mol

Answer:

1652 kJ/mol
