Methane (CH4) is a gas that is found in small quantities in Earths 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 forms covalent bonds

it forms four bonds because carbon has a valency of 4 bonds so to fill its octate carbon forms covalent bonds with 4 hydrogens

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
