The energy that is
essential to break one C-H bond is 414 kJ/mol. Since, there are four C-H bonds
in CH4, the energy Δ HCH4 for
breaking all the bonds is calculated as Δ HCH4 = 4 x bond energy of C-H bond. By
multiplying the 4 with the 414 kJ/mol you can get the answer of 1656 kJ/mol CH4
molecules.
Answer:
A
Explanation:
Matter is anything that has weight and occupies space. Weight is synonymous to mass
D is the answer since it is changing the element.
Actually, I strongly believe it is a switch.
