hi! please help me answer both 2a and 2b

2. (a) One of the ways to produce hydrogen gas for hydrogen fuel cells is to react methane (CH4) with molecular oxygen to produce CO and hydrogen gas. This is an endothermic reaction. Write a balanced chemical equation that including the word "energy" as one of the substances that represents the endothermic process. (b). A 6-kilogram hydrogen tank vehicle can have an estimated range of 300 miles or more. Use the balanced chemical equation in 2a to calculate the amount of methane needed to produce 6 kilogram of hydrogen gas
