Rust (Iron(III) oxide), is produced when metallic iron reacts with oxygen gas in the presence of moisture in the air.

a. Write and balance the equation.

b. how many grams of iron(III) oxide are produced when 120 g iron rusts? 9.675 mol of oxygen gas.

c. If 5.8 L of oxygen gas were present, how many moles of Iron(II) oxide would be produced?

d. If 1.204 x1024 formula units iron(III) oxide of were produced how many liters of oxygen gas would be needed?

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.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
