Answer:
The correct answer is 1. 219 grams this is arrived at by considering the actual yield of the reacting compounds
Explanation:
We are given the equation for the chemical reaction as
Al2S3 + 6 HCl → 2 AlCl3 + 3 H2S
From where we have 1 mole of Al2S3 reacting with 6 moles of HCl to form the products
Thus 30 moles of HCl will require (1/6)×30 or 5 moles of Al2S3
However 1 mole of Al2S3 is 150.16 grams thus 5 moles = 5×150.16 = 750.8 grams ≅ 751 grams
Percentage Yield = Actual Yield /Theoretical yield × 100%
As the reaction has a 29.1% yield, it shows that only 29.1 percent of the expected product is actually produced
Hence the amount of Al2S3 required = (29.1/100)×751 = 218.5 grams ≅ 219 grams
A) each side of the equations is divided by the number of moles.
The answer is same atomic number!
<span>You have the answer and you don’t even know it. Just take the inverse of what one electron weights in grams (9.11E-28) to get the number of electrons in one gram. You should get an astonishing large number (1.10E+27). Just in case you do not recognize the notation it is scientific notation as a calculator would write it.</span>
Here is the correct answer of the given question above. Ferrocene has a higher melting point that acetylferrocene because it takes more energy to overcome the intermolecular forces between atoms. <span>Acetylferrocene melts at 80 degrees and Ferrocene melts at 170. Hope this answer helps.</span>
