Answer:
These tests determine the solubility of the compounds formed upon adding the test solution
Explanation:
Addition of Ba(NO₃)₂ will cause a precipitate ((Ba)₂SO₄) to form in the solution of (NH₄)₂SO₄. No precipitates will form in the other unknown solutions. Thus, whether or not the solution is ammonium sulfate can be determined.
Addition of NaCl solution will cause a precipitate (AgCl) to form in the solution of AgNO₃. No precipitates will form in the other unknown solutions. Thus, whether or not the solution is silver nitrate can be determined.
If no precipitates form, then the unknown solution must be KCl.
Answer: 5.72 g mass of carbon dioxide was produced
Explanation:
Moles of C =
Mass of 
reacted = 59.1 g - 17.5 g = 41.6 g
Moles of 
According to reaction 1 mole produces 1 mole of 
then 1.3 mole of will produce 
moles of
Mass of :
=Moles of × molar mass of = 1.3 ×44 g/mol =
=57.2 grams
5.72 g mass of carbon dioxide was produced
