PLEASE PLEASE PLEAS HELP ME WITH THIS, ITS DUE TOMORROW 03/02/2021 AND IM SO LOST. 50% of grade Iron metal is produced from the mineral hematite (Fe2O3) and pure carbon, as given by the equation:

Fe2O3 (s) + C (s)  -> Fe (s) + CO2 (g) [unbalanced]

Balance this equation. Then, use the mole ratios therein to perform the calculations below.

a. How many moles of C are required to completely react with 14.251 moles of Fe2O3 (hematite)?

b. How many moles of Fe2O3 must react to generate 0.986 moles of pure iron?

c. How many moles of CO2 will be generated if 2.774 moles of carbon completely reacts?

d. What is the limiting reactant?

e. Calculate the mass of excess reactant that remains when the reaction is complete.

f. When this reaction is performed in the laboratory, the percent yield of CO2 is 72.6%. What was the experimental yield of CO2?

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

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.

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
