Find the number of grams of zinc (Zn) metal that will completely react with 730 grams of hydrochloric acid (HCl) to produce zinc chloride (ZnCl2) and hydrogen gas
(H2).

Write the balanced chemical equation.
Use coefficients from balanced equation to determine mole ratio.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

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 scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
