Rewrite each equation below with the delta h value included with either the reactants or the products and identify the reaction as endothermic or exothermic.
a) h2(g) + o2 (g) -> h2o (l);
deltah^0 = -285.83

b)2mg(s) +o2(g) -> 2mgo(s); deltah^0 =-1200kj

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the answer is c i took the test
