Answer:

Explanation:

The quantities in grams of each reactants are

$94.51 g Al$

$1.873.10^2 g Fe_2SO_3$

The grams of $Fe_2SO_3$ 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

$1,873.10^2= 187,3g Fe_2SO_3$

Quantities of reactans expressed without scientific notation

$94.51 g Al\\187,3 g Fe_2SO_3$

The amount in grams of Al is less than the amount of $Fe_2SO_3$ therefore it will be finished first.
