When silver nitrate is added to an aqueous solution of magnesium chloride, a precipitation reaction occurs that produces silver chloride and magnesium nitrate. When enough AqNO3 is added so that 19 g of MgCl2 react, what mass of AgCl precipitate should form?
The ultimate source of all chemical products is the earth (including its water and atmosphere). Sulfuric acid is a good example. It is made from burning sulfur in air to make sulfur trioxide then reacting the sulfur trioxide with water.
