Answer:

Al

Explanation:

The quantities in grams of each reactants are

[tex]94.51 g Al[/tex]

[tex]1.873.10^2 g Fe_2SO_3[/tex]

The grams of [tex]Fe_2SO_3[/tex] are expressed in scientific notation

Since the power of ten is positive and is iqual 2 we must run the comma two spaces to the right

[tex]1,873.10^2= 187,3g Fe_2SO_3[/tex]

Quantities of reactans expressed without scientific notation

[tex]94.51 g Al\\187,3 g Fe_2SO_3[/tex]

The amount in grams of Al is less than the amount of [tex]Fe_2SO_3[/tex] therefore it will be finished first.
