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 up this resource as fuel for space propulsion. Most of this resource currently used is (*) “gray,” but more investment is moving toward its “green” form and its “blue” form, which uses carbon capture technology. The Toyota Mirai (10[1])was one of the first (10[1])mass-produced vehicles to use this resource in its fuel cells, 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■
