Answer:
C) 3.37 moles
.
Explanation:
Hello,
In this case, considering that the atomic mass of aluminum is 27.0 g/mol, the moles in 90.93 g of aluminum are computed via the following dimensional analysis:
Thus, answer is C) 3.37 moles
.
Best regards.
According to your equation, for every mole of iron oxide (Fe2O3), it takes 3 moles of carbon monoxide (CO). So for 1.75 moles, it takes 3 times as many moles of CO.
1.75 x 3 = 5.25 moles of CO.
I think your product is CO2. Dalton's Law sayeth that the coefficients tell us the ratios of moles. So if you hve 1.75 moles of Fe(III)oxide, 3*1.75 moles of CO are needed (in theory) to react completely. The answer is requested in moles, so you need go no further.
Would it be 8 divided by 2 so 4? That seems like the most logical way to get answer for this although I don’t quite know the process of whatever your doing so I could be wrong.
True.
Sulfur is in the same column of the periodic table as oxygen, but has electronegativity similar to carbon. ... Hydrogen Bonds (The polarity of a water molecule allows the oxygen of one water molecule to bond weakly to the hydrogen of another water molecule.)
