Methane (CH4) is a gas that is found in small quantities in Earth’s atmosphere. Which type of bonds does methane have, and why does one carbon atom bond with four hydrogen atoms? In three to five sentences, explain your answer in terms of valence electrons and electronegativity.

Methane have 4 covalent bond. One carbon form bond with 4 hydrogen bond because carbon need 4 valence electron to complete it's octet. Carbon has 4 valence electron. It need 4 electron to complete it's octet so it form bond with 4 hydrogen bond.And hydrogen has 1 valance electron so they easily complete the octet and form covalent bond.

Ithink the answer is c i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.
