Work is loosely defined as Force*Distance (there is also an angle element in the formula), so if the work done is 528 joules, then F*d should also equal 528. If you divide 528 by 1.1 (dividing “d” over in W=Fd), then you find that her weight is A. 480 Newtons. Hope this helps!

Which of the following is a valid mole ratio from the balanced equation 2Fe2O3+3C yield 4Fe+3CO2
riadik2000 [5.3K]

Answer :

The balanced chemical reaction is,

2Fe_2O_3+3C\rightarrow 4Fe+3CO_2

From this balanced chemical reaction, we conclude that

Therefore, the valid mole ratio from the balanced chemical reaction is,

Fe_2O_3:C:Fe:CO_2=2:3:4:3
