A 2015 paper by Zgonnik et al. argued that the Carolina Bays release this resource in a manner similar to arid patches of land called fairy circles. This resource powers the village of Bourakébougou, Mali after a large deposit of it was found there in 2012. That form of this resource is the lighter of the two byproducts produced by serpentinization. A Bussard ramjet scoop (-5[1])up this resource as fuel for space propulsion. Most of this resource currently used is (*) “gray,” but more investment is moving (10[1])toward its “green” form and its “blue” (-5[1])form, which uses carbon capture technology. The Toyota Mirai was one of the first mass-produced (10[1])vehicles to use this resource in its fuel cells, (10[1])which emit water as an output. Combined with nitrogen to form ammonia, for 10 points, name this gaseous element that is the lightest element in the universe. ■END■ (10[1])
