Which describes what will happen to the H+ when these reactants form products? H+ binds with NO to make a salt. H+ binds with Ca2+ to make an acid. H+ binds with OH– to make water. H+ binds with Ca2+ to make a base.
H+ will bond with OH- to make water, because out of these options those are the only two with opposite charges (and remember opposites attract). Plus if it is an acid base reaction water must be a product (along with a salt).
