Question #f8efe

Answer 1

Limiting substance is sodium phosphate.

Explanation:

First compute the 1st and 2nd compounds molecular weights:
The first compound's MW = 164.14 grams/mol
The second compound's MW = 163.94 grams/mol.

Now their moles are:
The first compound's mol = 2.5/164.14 = 0.01523
The second compound's mol = 2.5/163.94 = 0.01516.

Thefore sodium phosphate is the limiting chemical compound in this reaction.
