Answer to Question #338437 in Inorganic Chemistry for Lean

Question

Steel wool , which is made of pure iron metal, burns with oxygen gas to produce ferric oxide (Fe2O3). Fe(s) + O2(g) ( Fe2O3

If there are 1.25 moles of Fe and 1.25 moles of O2,

How many moles of Fe2O3 will be produced? What is its mass?

If the actual laboratory yield is 95.8g Fe2O3, what is the rection’s percent yield?

Pure aluminum (Al) metal reacts with hydrocholoric acid (HCl) to produce aluminum chloride (AlCl3) and hydrogen (H2) gas.

Write the balanced chemical equation for the reaction described above.

If the expected mass of AlCl3 to be formed is 3.5g, what should be the initial mass of the pure aluminum metal?

If the actual mass of AlCl3 produced is 3.1g, what is the percentage yield of the reaction?

Answer 1

1) 2.5 moles 55 grams

2)63%

3)2Al+6HCL=2AlCl3+3H2

4)2g

5)66%
